Product properties: Triglycidyl Isocyanurate (TGIC) is an isocyanurate based crystalline polyepox-ide compound, it has better heat resistance, weather resistance, adhesion and excellent high temperature stability. It is mainly used for the curing agent, insulating laminate sheet, adhesive, plastic stabilizer and so on.

The harden principle of polyester-TGIC powder coating is the ring opening polymerization by carboxyl-containing polyester resin and TGIC glycidyl to form cross-linking film. During the process of Polyester powder coating’s curing to film, no volatile matter, so polyester -TGIC powder coatings can form thick coating without cells. Triglycidyl Isocyanurate (TGIC) is an isocyanurate based crystalline polyepox-ide compound, it has better heat resistance, weather resistance, adhesion and excellent high temperature stability based on its structure , it is widely used as a cross-linking agent or curing agent in outdoors industries as curing agent. TGIC is mainly used as the followed industries:

 

Powder coating is widely adopted by European aluminum building materials, 60% extrusion-type material of aluminum doors and windows is adopted by TGIC or polyurethane for painting.

In the early period of electrostatic powder coating’s application, the exact example is road-guiding board. Since the better corrosion-resistance than solvent coating, powder coating technology is widely adopted by the national as the road-guiding boards. Nowadays, polyester or crylic acid replaced epoxies powder coating for its better weathering resistance.

Polyester or acrylic powder coating has been adopted as light truck performance technology in the abroad.

Automobile and motorcycle accessories or tires, body of bicycle and isolation fences for road.

Air condition enclosure and household gas stove board, etc.

Garden tools, armrest and fence, etc.

Agricultural equipment and telegraph poles, etc

Carboxyl-containing polyester resin can be used with the maximum amount 10% of the TGIC for cross-linking curing, the combination by carboxyl-containing polyester resin and a certain percentage of TGIC is defined as Polyester-TGIC powder coating. The performance of film depends on the type of polyester, additives, pigment fillers and the technology during the process.

 

Production facilities for polyester coating is similar to epoxy coating, and the process of technology is firstly crashed the two resins into 20-60 mesh, add the ingredients by specific proportion into high-speed mixer with 5 to 15 minutes, then move the material to type SLG-50A double screw extruder for mixing, entrance of the extruder 60-80℃, the exit is 110-120℃, cool them off, reenter the crushing screen(grinding ACM) crushed materials sieve by grade, particle size above 180 mesh will pass 100%, through the check of qualified packing, number, storage, the whole process ended. Polyester powder coating production process can be divided into the following steps: Resin coarse crushing - ingredients - Pre-mixed - melt mixing - Cooling - fine crushing - rating Filter - inspection – put into package – set serial number - packing - storage.
