KD300 Polyurethane Powder Coating

Introduction:
Using high quality carboxyl resin and hydroxyl alkyl amide (HAA) curing agent as major raw material, which has good climate resistance and salt spray resistance properties.
Application Fields:
Suitable for any of exterior metallic products: agricultural equipments, car parts, courtyard fence, fitness equipments, exterior lights, exterior air-conditionings and architecture materials etc.
Characteristics:
Excellent adhesion between coating and substrate. Good mechanical, heat-resistance and chemicals-resistance properties. The film also has fire-retardant and extinguishing property to some extent. This product is safer, more environmental, and healthier than TGIC type. There will be pinholes if the thickness of the film is more than 100 μm. 
Features:
