A Polyurea coating is a reaction of two chemicals (Isocyanate and Amine 1:1, solvent free) which after reaction result in a durable and elastic polymer. We spray polyurea coatings with high duty hot airless pumps. The two separate components are heated to 70°C in the pump casing. We then mix both components in the spray pistol in a fraction.
After mixing the components (at a huge speed of 12 litres per minute) a thermal reaction occurs in the product and the temperature rises to 74°C. That means the Polyurea coating is hardened and ready for loading in 5 seconds.
