Product Details

Nano Calcium Carbonate for Sealant 

 (NCC-602 FOR ADHESIVE)

Nano calcium carbonate NCC-602  for sealant uses a unique surface treatment technology, a special surface activation treatment. Mainly used in silicone, coverging, polyurethane, epoxy and other sealed structural adhesive. 

Application characteristics: nano precipitated calcium carbonate NCC-602 used in sealing adhesive material, and the rubber has a good affinity, nano CaCO3 NCC-602 can accelerate the glue cross-linking reaction, greatly improve the system thixotropy, enhance dimensional stability, improve the mechanical properties of rubber, and add large quantity, to achive the dual role fo filling and reinforcing. At the same tiem, Nano Calcium Carbonate NCC-602 can make the surface of the compound bright and delicate.
