Composition
This product consists of two components: an emulsion and a color
paste. The main resin system is composed of epoxy resin, isocyanate
crosslinking agent, and toughening agent, which are neutralized
with acid to form the emulsion. The dispersion resin is epoxy
resin, and the color paste is prepared by grinding pigments and
fillers.

Bath Preparation
Color paste : Emulsion : Deionized water = 1:3:4 (by weight). Add
appropriate additives and neutralizing agents to adjust the
parameters. Let the mixture age for 48 hours, then filter and
apply.
