Matting Agent as Matting Hardener Used For TGIC Powder Coatings
MATTING AGENT TC-70 is a matting hardener with TGIC as co-reactant, which can provide low-gloss of ca.10% (60°), good impact and exceptional flow properties for exterior durable PES/TGIC powder coatings. It may also be used in both epoxy and epoxy/polyester hybrid powder coating with low-gloss finish.
Appearance Very fine pale yellow powder [visual]
Chemical equivalent weight (g/eq) 92 [calc.]
Herein described to be typical properties and do not constitute specification limits.
Matting agent for Polyester/TGIC powder coatings
1, It 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.
2, Curing @ 200℃(metal temperature) are required for both better flow and impact properties.
Use method & levels
1, TC-70 with other components of the formula before extrusion.
2, The use level is 1-5% by total weight of formulation, depends on the gloss required.
3, Ca. 1.1-1.2 parts of TGIC per weight part of TC-70 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.
Package & Storage
1, Packaging with PE lined Kraft paper bags. Net weight 25kg per bag.
2, Store in temperature between 2-32℃ or cool dry place. Keep away from heat and fire.
3, Based on our experience the shelf life of TC-70 under above conditions is at least 2 years.
● When formulating TC-70, the gloss of coating will be determined by its concentration and the selected polyester resins. It is important to select matched resins.
● The powder coating formulated by TC-70 have a bit yellowing tendency and poor wet-thermal resistance.
