Polyurea is a result of the reaction of diisocyanates and diamines. It is one of the most durable synthetic polymer materials. Here are just a few of the many attributes it has:
- High strength, with tensile strength greater than 5,000 PSI and tear strength greater than 500 lbs/in
- 100% solid, with no volatile organic compound (VOC).
- Large hardness range, adjustable to shore D
- Excellent chemical resistance
- Superior resistance to abrasion
- Water-tight properties
It is possible to react quickly between diisocyanate, diamine and polyurea. Exothermic heat pushes the reaction towards completion. It is not necessary to have a complicated reactor or adhere to strict conditions.
This allows you to mix the two components in a calculated ratio and then apply the mixture to a substrate. You can apply different thicknesses of tough polyurea coatings to any substrate. A high-pressure spraying machine is used to spray a polyurea coating uniformly on the surface. This is the foundation of fast-setting polyurea paint systems.
Polyurea Spray Coatings are fast-setting and can be used in a variety of industries and markets. Common raw materials require low viscosity and low freezing points. They also have high fast reactivity. For its protection purposes, these raw materials must create a thin, high-strength layer. ArmorThane offers additional raw materials that can be used to improve product performance and offer new solutions.
Polyurea spray systems are versatile and a great choice for many applications. This blog is intended to encourage and start discussions about improving existing systems and creating new ones that are more durable, long-lasting, and efficient.
