Powder coating resins for HAA cure low gloss matt dry blend Polyester Resin NH6381/NH6688

Applications:

NH6381/NH6688 are saturated carboxyl polyester resins for low gloss polyester/primid powder coatings by dry blending procedure.

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.
