Application fields
>Coating: On the basis of the original formula of water-based latex paint, after adding % of the total weight of nano-silica (which needs to be fully dispersed), its suspension stability, bonding strength, smoothness and other properties between the thixotropic coating and the substrate are significantly improved, and the drying time The artificially accelerated UV aging test time is shortened, the time of the artificially accelerated UV aging test is doubled, the washing resistance is increased from thousands to tens of thousands of times, and the stain resistance of the coating is also significantly improved.
Plastics: Nano-silica is fully dispersed in plastic raw materials such as polypropylene and polyvinyl chloride, which can greatly improve the strength, toughness, wear resistance and aging resistance of plastic products. For example, through nano-modification, its water absorption, insulation resistance, compression, residual deformation, flexural strength and other major performance indicators have reached or exceeded engineering plastic nylon. The weather resistance of the product has more than doubled, and it can replace nylon in some fields.
