Herein described to be typical properties and do not constitute specification limits.
Matting agent for Polyester/TGIC powder coatings
Can provides low gloss of ca.10% (60°), exceptional flow and good mechanical properties such as direct impact for PES/TGIC based exterior durable powder coatings.
Curing @ 200ºC(metal temperature) are required for both better flow and impact properties.
3. Use method & levels:
TP3328 with Other components of the formula before extrusion.
The use level is 1-5% by total weight of formulation, depends on the gloss required.
Ca. 1.1-1.2 parts of TGIC per weight part of TP3328 based on their chemical equivalent weights. Varying their total concentrations of in the formulation can control different gloss levels of coating when both ratios were retained at above fixedness.
|polyester resin TP9035||200|
|Flowing Agent TP88||4|
5.. Package & Storage:
Packaging with PE lined Kraft paper bags. Net weight 25kg per bag.
Store in temperature between 2-32ºC or cool dry place. Keep away from heat and fire.
