SACHTOLITH
ZnS
VENATOR high purity functional white pigment (White Pigment)
Two grades
L Grade
Pure Zinc Sulfide (ZnS) Powder
HD-S Grade
Zinc sulfide (ZnS) with enhanced dispersibility by adding a dispersant
Example of use - Glass Fiber Reinforced Plastic
The addition of rutile TiO2 to PA66 reinforced with glass fiber significantly degrades mechanical properties.
However, the replacement of white pigments with ZnS with a Mohs hardness of 3 minimizes deterioration of properties.
Example of use - UV Curing Paint
Compared to TiO2, the end of the light absorption spectrum is greatly shifted into the ultraviolet region.
With the efficient activation of the photoinitiator, the curing of the thicker white UV coating is faster and more complete.
Example of use - Flame retardant
It can replace some or all of antimony trioxide (Sb2O3).
Since it is a white pigment, it is possible to reduce the amount of TiO2 in addition to replacing Sb2O3.
It can be applied as a flame retardant to PVC, PP, PA, etc.
Can be used in the following fields
Paint Coating Printing Ink UV Paint Powder Coating Adhesive Plastic Duroplastic
Master batch Elastomer sealing and insulating compound Plastic bearing Lubrication coating
Friction lining Flame retardant
