One Component Waterborne Epoxy Ester Resin
Epoxy coatings are formulated based upon the performance
requirements for the end product. When properly catalyzed and
applied, epoxies produce a hard, chemical and solvent resistant
finish. They are typically used on metal and steel to give
resistance to water, alkali and acids.
WL-172is a high solids, VOC compliant, single component chassis
paint and underbody coating specially formulated to permanently
stop automotive and truck corrosion without the use of primers or
topcoats.

Waterborne Epoxy Ester Resin, Cosolvent, Neutralizing Agent, Water
2, Typical Date
| Type of polymer | Waterborne epoxy ester resin |
| Non-volatile(%) | 74±2 |
| Viscosity( 25℃, mpa*s) | ≤200* |
| PH | ---- |
| Neutral.agent | Non neutralization |
| OH value on solids (mgKOH/g) | ---- |
| Air dry | Applicable (Oxidation Cross-linking) |
| Cross-Linking with amino resin | Inapplicable |
| Grinding | Applicable |
| Drying speed | better |

PS:The Viscosity with*is measured in the case of the resin diluted
by equivalent amount of propylene glycol methyl ethe*
3, Product Properties:
Excellent anticorrosion performance, especially for the preparation
of anti-rust base coating;
Fast drying speed, good hardness;
Excellent salt fog-spray resistance and early water resistance:
Good storage stability;
Excellent shear stability, can be grinded with dispersions
directly.
4, Instructions:
WL-172A can be diluted with deionized water or lower alcohol or
alcohol ethe* to white emulsion. It can be dried by oxidation
cross-linking addingoily/water driers at normal temperature or
low-temperature baking. The oily driers need to be diluted by the
solvent such as butyl alcohol or ethanolfor use.
The water dispersion of WL-172A is stable at neutral or slight
alkaline conditions pH value has to be carefully observed in
coating production sinceprecipitation may occur if acidic pigments
like carbon black are used in the system. PH value of the coating
system can always be adjusted
triethylamine or N, N-dimthylethanolamine. Viscosity of the
dispersion will increase as the PH value increases.
5, Applications:
Air-drying or low temperature baking antirust coatings.
