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.
Appearance and physicochemical indexes
Loss on ignition
34.5 ～ 37.5%
Fineness≤45um (325 mesh)
0.8 ～ 3.5％
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)
ordinary paint and mill base、ink、auto-primer、 industrial paint、anti-corrosion paint 、 marine paint、carpentry finish
Package and storage
The package consists of external package (brown paper bag) and internal package (polyethylene film bag). The valve bag is also available and the weight is usually 25 0.25Kg. The package can also be customized. If stored in dry place and kept packaged (at the temperature of 0℃ ~30℃ ), the organic bentonite is effective within 36 months.
