High Quality Powder Coatings for Construction Aluminum Profile in Different Colors
This product is synthesized by saturated polyesters, with thermosetting properties and abundant color choices, excellent mechanical properties, gloss retention, color retention, leveling and anti ultraviolet rays. Our powder coatings can form a good protection layer on surfaces of aluminum profile and galvanized steel profile which is widely processed for walls, window frames, doors, balcony fences, rails. We can develop designated color, gloss and texture for our customers.
Advantages:
•no limit of color choices, RAL color atla, pearly luster, metallic selective;
•different kinds of glosses and textures selective, such as matt, common gloss, high gloss, ripple, hammer tone, and wrinkle texture, etc;
•we can offer heat transfer printing coatings;
•environment friendly(without heavy metals, no volatile, TGIC-free is selective);
•easy application, be facilitated to increase production efficiency.
Our aluminum profile designated powder coatings are of super color retention ability, can be used in hostile environment, with anti-cracking, anti-fading, color and gloss retention ability.
These series of powder coatings surpass China or international criteria:
•AAMA2604-02(American Architectural Manufacturers Association) ;
•(Britain Aluminum Profile Standard) BS 6496
••(Britain Galvanized Steel Standard) BS 64971
•China Aluminum Profile Standard) GB5237.4
