Organic bentonite: YH-958

Product  features

YH-958 is an improved rheological additive based on YH-938. It has high efficiency of gelling and thixotropy, and it is easy to disperse and the dispersion fineness is very small. It can be used in low to medium polar systems. YH-958 is equivalent to overseas SD-1 etc. It is widely used in the fields of paint, ink, sealant, oil drilling, grease etc.

Use method

YH-958 can disperse and dissolve in organic solvent and resin system at normal atmospheric temperature. And the viscosity of the system can be rapidly increased and the  system has the property of thixotropy.

The amount of YH-958 is usually 0.2~3.0% of the system (by weight)
