Nano-SiO2 content size color difference (AE value) impact on the form of microcapsules, the hard fumed silica particles embedded in soft organopolysiloxane changed the polarity of the particle surface, reducing the system viscosity. For the production of scratch-resistant acrylic paint. Scratch resistance of such coatings are particularly good. Its wear resistance is ten times the conventional acrylic systems, good quality silica Which, easy to apply and environmentally friendly radiation curing and solvent-free systems. Application of sealants and adhesives in the field of silicone sealants and adhesives, fumed silica used as a thickener and thixotropic agents, can increase the bond strength to ensure the free flow of silica Which is guaranteed, prevent caking and flow during cure hanging, scattered collapse, depression, silica, transparency, reinforcement, shear effects. Thickening and thixotropic fumed silica mechanism of action is when it is dispersed in sealants and adhesives, hydrogen interactions between different particles through their surface silanols, the silica aggregates to form a network, so that the system The restricted mobility, increased viscosity. Play a thickening effect; subjected to shear force under the action of a silica network is damaged, resulting in decreased viscosity. Thixotropic effect occurs, to facilitate construction. Once the shear force removed, the structure of such a network may be re-formed, effectively prevent the plastic material during curing of sagging.
