Water Based Coating

Back Ground

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.
