Polyurea Spray Application Technology
A Scientific Approach to Surface Protection

What Is Polyurea?

Polyurea is a highly elastic polymer coating formed through the chemical reaction of two components:
Component A: Isocyanate
(Polyisocyanate Blend)
Component B: Aminopolyol
(Resin with Additives)
When mixed under high pressure, the components undergo an instant polymerization reaction, forming a seamless monolithic membrane.
Application Process
