KS-40
Suitable for the Ultra high strength silicone sealant
KS-40 is a surface treated, super ultra-fine and very narrow particle size distribution precipitated calcium carbonate as the functional additives using in the ultra-high strength silicone sealant.
KS-40 is a functional additive providing the good compatibility and dispersity in sealant system. Especially has the excellent reinforcement, thixotropy, and low proportion, can significantly improve sealant products collapse resistance, elastic recovery rate, tensile strength, and elongation at break.
