English Name: refining penetrant
summary:Penetrant, also known as wetting agent, can reduce the surface tension or interfacial tension of liquid and make solid materials more easily wetted. Due to the reduction of surface or interfacial tension, water can expand or penetrate on solid materials and wet them. It is often used in the preparation of pigment paste, emulsion paint and color paint. Sometimes it can also be used as emulsifier, dispersant or stabilizer. It has strong penetration, wetting, dispersion and certain refining auxiliary functions. Wetting and penetration are one of the important properties of penetrant.
