NCO-OH is traditional polyurethane :Slow react speed(4-6h), construct solid conent (30%-60%)
NCO-NH2 is traditional spaying polyurea:Construct solid content 100%,quick react(some seconds), need to reply on big specialist spraying equipment for construction.
NCO-NH is Polyaspartic polyurea:
Construct solid content(70%-100%),moderate react speed, adjustable, can control to 20-120 minutes, can construct by traditional method.
Aspartic polyurea chemical react principle
Aspartic polyrea performance feature
PA resin is a high solid, low viscosity(100% solid, viscosity 800-1200mpa.s/25℃, aliphatic special resin, because of those feature, PA material possess following special performance.
A. Construct solid content: 70%-100%
B. Quick dry, quick to package, quick react by low temperature, one time film forming, quick construct speed.
C. Excellent anti-QUV performance, highest great can pass 4000hQUVa test.
D. Anti-corrosion, anti-abrasion, anti-impact,elastic material(400%,25MPa),hard material(2H)
E. Roll, brush,spraying machine,etc construct way.
