Detailed Product Description

Detailed Product Description

It is a surface treated, super ultrafine and very narrow particle size distribution precipitated calcium carbonate specially formulated as functional additive in sealants and adhesives and rubber products.

Applications:

It can be applied in polyurethane, silicone electronic adhesive, silicone building sealants, poly-sulfide sealant, epoxy resin adhesive, Rubber products etc.

NPCCA201 is a functional additive providing thixotropy and viscosity control resulting in improved sag and slump characteristics. Physical properties are improved due to the semi-reinforcing performance of NPCCA-201.
