Audited Supplier 1, water content is low, near neutral, and has good chemical stability, not with the adhesive in the adhesive, such as the
occurrence of chemical reactions.
2, adding amount, can greatly reduce the cost of adhesive products (such as: the amount of silicone rubber sealing pad for more than 50%, the amount of polyurethane adhesive for 20-30%).
3, with reinforcing effect, can improve the mechanical properties of the adhesive, lowered the curing shrinkage and thermal expansion coefficient, increase the thermal conductivity, improve heat resistance and adhesion, improve the mechanical strength
(hardness and compressive strength and corrosion resistance; the adhesive agent to lubrication and improve the technological conditions and the bonding properties are comprehensively improve the.
4, nano calcium carbonate particle small size, large specific surface area, after surface treatment and adhesive has good
miscibility in adhesive system can be used as a thixotropic agent, modulate adhesive viscosity, prevent adhesive in the vertical plane construction occurred droop and improve the retention characteristics.
5, in the process of calcium carbonate to produce nano pigment easy coloring, does not affect the color of products.
6, in different adhesives with different change role, in the PVC plastic sol can improve the rheological properties; in structural silicone sealant can serve to increase the strength and wear resistance; in the hot melt adhesive can play to the increment of the reinforcement and the heat effect; in water-based adhesives can act as thickening and increasing the viscosity.
