Instruction:

1. Slight overdose in the formulation will contribute to improve flow and matting performance.

2. Obtain better matting performance by adding matting filler.

3 Add moderate curing catalysts in the formulation to improve the impact properties, which may lead to gloss and flow fluctuation.
