NH8081&NH8588 Low Gloss Durable Polyester Resin in Dry Blending
◇ Applications:
NH8081/NH8588 are saturated carboxyl polyester resins for low gloss polyester/TGIC powder coatings by a dry blending procedure.
Because polyester resin has polar groups, the powder loading rate is higher than that of epoxy resin, it is not easy to yellowing during baking,
high gloss, good leveling, plump paint film, light color and other characteristics, so it has good decoration.
Generally used in refrigerators, washing machines, vacuum cleaners, instrument housings, bicycles, furniture and other fields.

Low gloss film
Excellent mechanical properties
Good resistance to chemicals and fine anti-yellowing
durable weatherability
