Super Durable Isocyanate Polyester Resin NH7809 for Polyurethane Powder coating
◇ Applications:
NH7809 is a hydroxylated polyester resin for polyester/isocyanate powder coating system.
The coating is prepared by mixing resin, pigment and filler, curing agent and other additives in a certain proportion, and then by hot extrusion, crushing and screening. They are stored stably at room temperature. After electrostatic spraying or fluidized bed dip coating, they are heated, baked, melted and solidified to form a flat and bright permanent film, so as to achieve the purpose of decoration and anti-corrosion.
◇ Basic features:
Excellent leveling
Good mechanical properties
Good chemical resistance
