The most commonly asked question we get, right after price, is what makes you different? Sometimes people want to know what makes us different from a bedliner or maybe what makes us different from coatings that are rolled on an RV and can be done at your location. We always think it is important to give our customers as much information as we can so you can make an informed decision.
There are many products used on RVs that were originally designed for other uses such as industrial roofing or truck beds. To understand what makes RV FlexArmor(R) different from other common polyureas, a little background on polyueas is needed.
Polyureas come in two different types, pures and hybrids. A pure polyurea, which is what RV FlexArmor(R) is composed of, consists of two drums. The A and B of these two chemicals never mix until they are sprayed from the gun. Once the two chemicals meet, they form a new product. Depending on the formula, pure polyureas can be created to meet different needs. RV FlexArmor(R)’s formula was made to have the strength, flexibility, fast get time and bonding ability needed for rvs and assorted substrates. A pure polyurea can be sprayed in all weather conditons without effecting the final product. Pure polyureas can be formulated to have a stronger bond than hybrids to almost any substrate due their chemical makeup. Since the two chemicals combining forms a new product, RV FlexArmor(R) is not effected by things such as humidity or residues left on substrates. Pure polyureas are a more expensive chemical and also have an extremely slow UV decay rate. They can last over 20 years in the sun before showing signs of aging.
A hybrid polyurea also comes in A and B drums. The drums are a formula and a catalyst. The catalyst side kicks off the chemical side, similar to an epoxy. This chemical reaction makes the poly side solidify. Since it is a catalyst reaction, the physical properties of hybrids are different than pure polyureas. Hybrids tend to have less flexibility and a much lower tear strength. Since it is formed by a catalyst, humidity, low temperatures and any kind of dust or oils on the sprayed surfaces can effect the curing of the hybrid polyurea. Hybrid polyureas are also not chemically designed to adhere to any surface that is not rough or pitted so do not form bonds on materials such as cleaned aluminum or plastics. Hybrids typically begin to show signs of UV exposure within 5 years.

Polyureas are not the same kind of material as some of the more common rv roof alternatives such as Liquid Rubber Roof or similar polymers. Comparing RV FlexArmor(R) or any other polyurea to these polymers is like comparing a shingle roof to a tile roof. They can be used in similar ways but have their own strengths and weaknesses. Polymer roof coatings have many uses and formulas, and vary greatly from company to company as to what they do, what the warranty covers and how they are applied and will give you many more hours of research.
