Nano Calcium Carbonate for silicon adhesive
(NCC-602 FOR ADHESIVE)
Nano calcium carbonate NCC-602 uses a unique surface treatment technology, a special surface activation treatment. Mainly used in silicone rubber (commonly known as glass glue), and silicone rubber / rubber or other adhesives and other good affinity, filling large, can reduce the amount of silicone rubber / rubber or other adhesives, significantly improve the thixotropy or shear-thinning behaviour of sizing material and other adhesive. Film formation is tight, strength is good and gloss and smoothness are increased. On the rubber or other adhesives to form a shielding effect, effectively achieve the purpose of anti-ultraviolet aging and heat aging. So that the sealant has a good storage stability, reduce production costs, improve market competitiveness, with filling and reinforcing dual role.
Nano calcium carbonate NCC-602 is mainly used for silicone rubber, silicone sealant, polysulfide gelatin, polyurethane sealant, adhesive, high-grade rubber, automotive PVC primer.
Application characteristics: good dispersion, rheological, good extrusion. Good adhesion, elastic elongation, good extrusion. Good thixotropy and excellent reinforcement, good elongation at break, good extrusion.
