Dry Blended Polyester Resin for Super Durable Matte Powder Coating
◇ Applications:
NH9001/NH9508 are saturated carboxyl polyester resins for low gloss polyester/TGIC powder coatings by a 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.
◇ Basic features:
Excellent leveling
Excellent weathering resistance
Excellent mechanical properties
Good chemical resistance
Good storage stability
