A Modern Alternative For Anti-Corrosion Protection




The relatively new on the scene, Polyurea two-component thermosets are chemically similar to the polyurethanes and are offered as aliphatic and aromatic applications. They are produced by the response of an isocyanate with an amine resin part instead of a polyol, just like polyurethanes. Polyureas can be used on their own or as hybrids with polyurethanes. They treat every readily to form soft to hard elastomers for usage on concrete floors or containments. They have the same benefits as %100 solids high-build coatings. Polyaspartic variations produce aliphatic items with longer pot lives to be applied by brush, roller, or spray.


Polyurea spray coatings technology is among the greatest advancements of the last 20 years. This innovation combines quick treating, even at extremely low temperatures, and water insensitivity with remarkable mechanical residential or commercial properties, chemical resistance, and durability.


The advancement of new basic materials and enhanced spray equipment has made it possible to overcome the preliminary issues of this innovation, such as substrate wetting, inter-coat adhesion, and complete surface area quality.


The latest advancement programs focus on extending the application fields through the introduction of MDI-prepolymers combining low viscosity with low NCO content, resulting in slower reactivity and greater flexibility. Additionally, prepolymers with higher NCO content produce coatings with remarkable hardness.


Inevitably coatings get harmed by external forces or by several long-lasting degradation procedures that impact the coating constituents. Normally this results in coating defects that expose the pipe steel to the environment around the pipeline, and this corrosion risk is and can be managed by cathodic protection.


Polyurea polymers are created to compete with tri-laminate products such as FBE, 3LPP, and 3LPE, offering greater performance coatings at competitive costs. The application processes required are basic and efficient and the equipment systems used are low-cost when compared to the costs of systems utilized in the application of FBE, Tri-Laminate, and similar coating technologies and not to mention the field joints which works on all of the above with added benefit of cost, speed and minimum back to service time.


Polyurea is characterized by lots of vital properties, which make it an efficient corrosion-resistant coating.


Water-resistance is perhaps the essential characteristic considering that water, as a universal solvent, in the mix with other materials can take various types and can create a destructive environment and have a destructive impact on the steel substrates. The incredibly low water absorption rates and moisture vapor transfer are necessary functions that make it a reliable coating barrier that extremely few coating can match.


The dielectric strength is a crucial home of Polyurea, which helps break the electrical circuit established during corrosion response and makes it suitable to be used as a corrosion-resistant coating by resisting the passage of electrons. Polyurea has a dielectric strength of > 16 VK and this integrated with low moisture absorption makes it an ideal anti-corrosion coating.


Polyurea coating's high resistance to ionic passage is the desired coating particular and avoids transfer or passage of chlorides, sulfides, or similar ions, which speeds up corrosion. Resistance to ionic passage is a contributing element to chemical resistance, and Polyurea is good for chemicals in between pH 12 and pH four, especially the alkalis.


The strong adhesion prevents the problem caused by a temperature gradient, osmosis, and electro-osmosis and keeps its integrity for a longer time, therefore boosting the coating life. A strong adhesion also avoids undercutting.


A well-developed elastomeric Polyurea has good resistance to abrasion, impact, and searching. The loss is < 6mg on the C17 wheel, comparable if not much better than most of the anti-corrosive coatings being purchased from today.


Among the characteristics that make Polyurea special is its retention of physical residential or commercial property on aging, making it weather and age resistant and making it suitable as a coating for long-term protection. A well-formulated Polyurea keeps more than 90% of its physical characteristics, even after aging.


Excellent external corrosion control on steel pipelines is attained by integrating Polyurea distributed with cathodic protection. The coating provides the first and significant defense against corrosion. In case of its damage, the cathodic protection serves to prevent pitting or basic corrosion where the pipe steel is exposed by damage to the coating. Coating damage is to be anticipated on all pipelines using conventional coatings, and the degree of damage with Polyurea is very little or none unless these are very roughly handled. For this reason, the degree of risk is less.


A good protective coating application always boils down to preparing the substrate or product it is applied to. Preparation is typically in the form of shot blasting or ultra-high water blasting, depending upon where the application is to happen and the product it is to be applied to. There are cold-used solutions that can be used utilizing a brush, roller, or squeegee.

Do New Trucks Require A Sprayed Bedliner?

 


When aiming to protect your new truck, one of the very first basic things you shouldto do is buy a durable and lasting truck bedliner. It's crucial not to let the weight of preservation rest on your paint job alone, and it's much more important to ensure you're purchasing the ideal type of bedliner.




Truck Bed 101:
Whether your bed is constructed of rolled steel, aluminum, or composite, there will be damage without proper defense. A paint task is inadequate to protect from the routine wear and tear of filling and discharging.
When your truck bed gets nicks and scratches, it exposes the metal under your paint to moisture and UV light, which results in corrosion.
Road conditions like gravel, salt, and general exposure to the elements will also speed along the rusting procedure by filling a vulnerable truck bed with much more nicks and scratches.
Carrying freight on an unlined truck bed can also lead to damage. Without the additional grip that a lining provides, there's a greater danger that your freight will damage your truck bed and also be harmed in turn.
Lining your truck bed will greatly lower the threat of corrosion and damage. It will also help keep your truck bed in excellent condition and boost your vehicle's resale value.

Which Bedliner is Best?
There are a lot of different kinds of liner choices available- from plastic drop-in liners to rubber adhesives. However, a lot of these "quick-fix" liners cause more trouble than they're worth and might result in more costs in the long run. Many liners can even be detrimental by scratching your truck bed or trapping wetness and particles between the liner and the truck.
Spray-on truck bedliners are an excellent way to protect the stability of your truck. They offer an airtight bond to the metal of your truck and keep a streamlined visual look in addition to lasting resilience. Using spray-on liner is low upkeep and economical to make certain your truck bed is protected and remains appearing like new.

Common Applicator Problems: SNAKES!

 

Copperhead Snakes in Crawl Spaces



Copperhead snakes are common in southern states.


Dealing with poisonous snakes in crawl spaces is entirely too common for spray foam and polyurea applicators in the south. Snakes can get into the smallest holes, rifts, and spaces so you should always check to see that those areas are tightly sealed. Some people use caulk for patching; nevertheless, caulk breaks down over time, and it may not be easy to fully apply it in hard-to-reach areas. Spray foam is a better option for precise sealing and a long-lasting fix. Spray foam’s expanding ability gets the foam into the tiniest cracks and other places where sealing is needed.



Homeowners can take steps to deter snakes around their homes by removing the snake’s food sources. Birdseed, dropped from bird feeders, attracts mice and rodents, a food source for snakes. Mulch can give a moist habitat and a food source for snakes because it invites insects and other small creatures. Raking up piles of mulch will help deter snakes. Some homeowners use mothballs to rid themselves of snakes; however, this has not been scientifically proven effective.




One means of capturing snakes in crawl spaces, under porches, decks, and other hard-to-reach areas, is to use a glue board. Once the snake is trapped, use a shovel to remove the glue board with the entrapped snake and move it far away from home. Pouring vegetable oil over the glue board can allow the snake to free itself. It may seem counterintuitive to free the snake, but snakes perform a good service by eating mice, rodents, and insects.



Snake handling devices, such as snake tongs, snake hooks, and a strike-proof snake bag to hold the snakes, can be used. Notwithstanding, it is prudent to train this type of work and know-how to identify various snake species. If you are uncertain, call a professional.




Working in Crawl Spaces is not for the Faint of Heart.

Unfortunately, most homeowners are unaware that snakes are lurking in their crawl spaces; therefore, the companies that work in those spaces often get a nasty surprise. While snakes are good at ridding us of mice, rodents, and insects, the nasty venomous ones can pose a problem for those who work in the dark, damp crawl spaces. While professional extermination services, snake traps, and an array of deterrent products are available, it takes time to make this happen. Crawl space workers usually don’t have time to wait out a snake, though, unless you’re an expert snake handler, it may be in everyone’s best interest to contact a professional exterminator and have the snakes removed from the area before doing any work.





Be Prepared

Home inspection organizations recommend wearing knee pads, gloves, a Tyvek polyethylene suit, goggles, hard hat, respirator with a HEPA filter, and carry a flashlight as well as a cell phone with you. Snakes and other critters can bite through bags as well as a Tyvek suit, so wearing a hazmat suit may be a better alternative. Keep in mind that some snakes can bite through leather, canvas, and denim. The highest number of snake bites usually occur on the hands and arms. Good light for crawl spaces is fundamental. This way, an inspection of the crawl space can assess possible concerns, such as architectural integrity, leaks, electrical wirework, chemicals, animal droppings, as well as critters.







What to Do in Case of a Snake Bite

In the event of a snake bite, apply pressure to the bitten area and an immobilization compress. Stay calm and still as much as feasible. Getting over-excited will cause blood to flow throughout the body more quickly, making the problem more serious. Do not wash the bite area or apply ice. Any venom residue left on the skin can help medical staff identify the snake species. Do not apply a tourniquet, cut into the wound, or try to suck out the venom. The human mouth is full of bacteria that can cause infection. Time means everything. Call 911 or your local crisis number and get help immediately. It’s always better to be safe than sorry. Crawl space workers deserve out of utmost respect and admiration. It’s a dirty and potentially dangerous job, often with numerous risks.



To learn more about potential risks and how to be prepared, we recommend calling ArmorThane. With over 30 years of experience, the go-to company comes to expertise and know-how of anything in the applicator business.

APPLYING YOUR FIRST POLY SPRAY COATING



So you've finally decided that polyurea spray coatings are the best choice for a secondary containment system for your wastewater storage tank. Not only is the polyurea solution waterproof, but it's unyielding to outside elements. You think you can apply the coating yourself even though you've never worked with these types of chemicals before.




But as you start applying the spray foam, you realize that something is wrong. The polyurea coating is not coming out evenly, and the coating doesn't seem to be sticking very well to the surface. You're probably reasoning – "What could i be doing wrong?" or "Is my equipment broken?"

This can happen quite often, especially if you've never used poly coatings before. That's why we have technicians on staff available at all times to help our customers get the right coating the first time around.




To help you get a consistent and effective coating on your first attempt, follow these tips:

  • Preparation is key: This is the biggest reason why the customer-applied coatings fail. If you don't prepare the surface properly, then the coating will not stick very well. Before you even prepare your equipment, take a look at the surface you're about to spray. Ensure it's clean of any oils, acids, salts, and additional elements that could impact the coating. With a clean and level surface, you should have no problem applying your coating.
  • Repair the damage: Before applying the solution, you should check to ensure no cracks. If so, fill in any cracks and make sure the concrete surface isn't damaged in any way. It would help if you considered replacing any caulking sealants as well.
  • Read the instructions: You may think this is an obvious tip, but following the instructions will lead to (almost) no chance of a bad coating. If the instructions are too confusing, we advise you to give ArmorThane support a call. You need to make sure you understand the process before applying a polyurea coating. You may also want to verify your equipment and materials to ensure everything is ready for the task ahead.
  • Prepare the area: You will need to install a primer on the surface. Next, bag off and mask the area to protect against any overspray, which includes any fixtures. You may want to use wire tape to get a clean-trimmed edge.
  • Spray slowly and smoothly: A few things can happen when you're spraying, such as over-spraying or issues with the spraying-off ratio. You need to be conscious of your surroundings when applying spray foam or polyurea. For instance, on a windy day, you're going to want to spray against the wind. Make sure you're wearing the proper protective gear when spraying into the wind because the applicator will be heavily exposed to over-spraying. You should also check if the solution is blended correctly before starting to apply the solution.

If you follow those tips, then you should have no difficulty when applying your polyurea coating.

Remember, it is best to get the polyurea coating applied right the first time, so it's extremely important you are well prepared and know what you're doing. Let ArmorThane Industrial Coatings assist! Contact ArmorThane today to get more information on their products and services.
