Adhesives and Sealants Industry


Used in sealant adhesives, it has good affinity with the adhesive and can accelerate the crosslinking reaction of the adhesive, greatly improving the thixotropy of the system, enhancing dimensional stability, and improving the mechanical properties of the adhesive. With a large addition amount, it achieves both filling and reinforcing effects. At the same time, it makes the surface of the adhesive bright and delicate. In developed countries, nano calcium carbonate has become a major raw material for reactive adhesives, hot-melt adhesives, chloroprene rubber adhesives, water-based adhesives, and sealants. While significantly reducing costs, the adhesive performance has been comprehensively improved. Modified nano calcium carbonate products have a wide range of applications. In silicone structural sealants, it can improve reinforcement and reduce costs. In adhesives and sealants, nano calcium carbonate after surface compatibility treatment can significantly reduce costs and improve adhesion performance. When used in hot melt adhesives, it can play a role in increasing reinforcement and heat resistance. In water-based adhesives, it can play a role in thickening and increasing viscosity. In PVC plastisol, it can improve its rheological properties.
