Waterborne Epoxy Modified Acrylic Resin WL-138
Water-Based Acrylic Modified Epoxy Resin WL-138 is a water-based
modified epoxy resin that appears as a water dispersion. This
product has been diluted with de-ionized water and has protective,
decorative performance, excellent adhesion and mechanical features.
It is stable to high shear speed and can be directly used in
grinding. It finds application in primer and self-priming top
coatings for hardware and auto parts

3, Product Properties
Excellent shear stability, can be grinded with dispersions
directly;
Fast drying speed, good hardness;
Excellent salt fog-spray resistance, early water resistance and
aging resistance.
4, Instructions
WL-138can be diluted with deionized water to construction viscosity
and be dried by oxidation cross-inking at normal temperature or
low-temperature baking.PH value has to be carefully observed in
coating production since precipitation may occur if acidic pigments
like carbon blackare used in the system. PH value of the coating
system can always be adjusted by triethylamine or
N,N-dimthylethanolamine. Viscosity of the dispersion will increase
as the pH value increases.
5, Storage:
Suggested storage temperature is 0-40℃. It is stable at neutral or
slight alkaline conditions. It is unstable that it is diluted with
acidic or impuritywater. Best be used within half of a year after
it is produced. The expired products can still be used after
passing the inspections.
6, Applications:
Air-drying or low temperature baking antirust coatings and top
coatings.
