2. Characteristics
● Apply to exterior durable PES/TGIC powder coating obtained by dry blending way to provide acceptable flow and ranges of from about 10-40%(60°) of low gloss depending on the used polyesters. In general, selecting slow-curing polyesters are favorable.
● The coating surface performance is depending on base coating powder as well as process control, such as appropriate powder particle size distribution. In most cases, as same as most of dual components of dry blending powders, film surface exhibits micro-roughness and bright spot.
● Satisfy to formulate low use level and low cost powder coating of requirement.
● Good mechanical properties and color/gloss stability.
3. Use method & levels
● Firstly, prepare an appropriate base coating powder followed by incorporating SA2061D into the said powder, then dry blending using a proper mixer.
● The use level is 1-1.5% by total weight of formula.
