Cold Spray Polyurea Cartridge Elastomer

Cold Spray Polyurea Cartridge Elastomer

Cold polyurea is applied with a simple spray gun, easy to apply,one person can operate it. It can be directly sprayed in the temperature above 25 ℃ , use a microwave to heat the liquid material to 35℃ if the environment temperature below 25℃. The curing time is adjustable from 2-10 min, can be sprayed forming on any curve, vertical or slope surface, without sagging. The coating is flexible, compact and seamless, with excellent comprehensive physical properties, no powdery, no peel off or crack after long term outdoor use, it is resistant to any cold & hot

impact and weather changing corrosion.
