Nano-scale activated calcium carbonate

Product Introduction：Nano-level activated calcium carbonate silicone sealant series 906, 908

This product adopts ** surface treatment technology for special surface activation. It is mainly used in silicone sealant (commonly known as glass glue), exhibiting good affinity with silicone sealant/rubber or other adhesives, and has a high filling capacity. It can reduce the usage of silicone sealant/rubber or other adhesives, significantly improve the "thixotropy" or "shear thinning characteristics" of the adhesive or other adhesives, form a tight film with good strength, and enhance gloss and smoothness. It creates a shielding effect on the adhesive or other adhesives, effectively achieving resistance to UV aging and thermal aging. It provides good storage stability for the sealant, reduces production costs, and improves market competitiveness, serving a dual role of filling and reinforcement.
