Gloss range:4%above @60°; Include a few waxes;
React with epoxy resin E12 by 1:2.3; Super stability;
Heavy mental conforms to RoHS requirement; Full and smooth film.
2) Incorporation and Processing Instructions
The product should be mixed with the resin, hardener, pigments, and other additives using a high-speed mixer and extruded along with all components.
1-5%additive(as supplied)based on the total formulation when extruding with all formulation components. More dosage for lower gloss. The above-recommended levels can be used for orientation.
Optimal levels are determined through a series of laboratory tests.
An appropriate amount of filler can improve the matting effect, which would influence the leveling.
An appropriate amount of accelerator can improve the impact resistance, which would influence the gloss and leveling.
