The market of water based coating continues to grow because of the below reasons.
1. Environmentally friendly
In order to reduce the amount of V.O.C. (Volatile organic compounds,) many coating manufacturers shift from Solvent coating to Water Based Coating.
2.Regulation
Coating manufacturers in the US are all forced by EPA to reduce the V.O.C.
- Be able to keep about 12 months.
- Coating method
General methods such as Spraying, Dipping, Rolling, Calendaring, Bar Coating - Lower dosage
about 0.3w/v% (in dry film) - Can be apply to both

- Disperse well before applying
In case not able to well disperse, please stop using it and make new coating with Ionpure. - 2 parts system Coating: Add to resin solution (Not into hardener such as Isocyanate)
- Store in dry area away from lights and humidity
- Please inform us of a thickness of coating in advance so that we can choose the most suitable grade.
