We Can Uniquely Offer Our Customers Weather Resistant Powder Coatings (Fluorocarbon Finish)

Architectural profiles are widely used in all aspects of buildings for their excellent durability, decorative properties and processing and molding properties. Aluminum alloy profiles, in turn, account for more than 80% of metal profiles due to their good processing performance, light weight and other advantages, and the application of powder coatings in aluminum profiles has grown rapidly.

At present, the surface treatment of aluminum profiles is anodic oxidation, electrophoretic coating and powder coating three treatment methods, each of which has its own advantages, in terms of environmental protection, powder coating is more advantageous, while powder coating in terms of color, pattern, gloss and other aspects of selective good, and get the people in all walks of life love. The representative powder coating varieties are epoxy type, polyester type, acrylic type and silicone resin type. As a practical application, such as aluminum frames, doors and windows, balconies, corridors, partition panels and other high corrosion-resistant aluminum profiles, most of the polyester, acrylic powder coatings; in addition, due to epoxy resin powder coatings have excellent adhesion, corrosion resistance, but poor weather resistance, for indoor or as a primer.

The polyester resin selected for architectural profile powder coating is saturated, and is divided into two categories of terminal carboxyl type (-COOH) and terminal hydroxyl type (-OH) according to its terminal base. Low acid value (20-45mgKOH/g) polyester with triglycidyl isocyanurate (TGIC), hydroxyl amide as a curing agent (Primid or HAA), end hydroxyl (-OH) polyester has been lactam-enclosed isophorone diisocyanate (IPDI) polyol prepolymers as a curing agent, the preparation of weathering superiority of the pure polyester Powder coatings with excellent weathering resistance are prepared.

According to the weathering requirements of powder coatings, foreign countries are usually divided into three levels according to the results of the Florida natural exposure test. 1:

1. Standard weathering powder coatings (can pass the Florida exposure test standard 1 to 2a) 

2. Improved weathering powder coatings (can pass the Florida exposure test standards 2 to 3a) 

3. Ultra Weathering Powder Coatings (passes Florida Exposure Test Standard 5a and above)
