Almost all the features Si02 applications thixotropic polyester resin and gelcoat in thixotropic polyester resin, fumed silica is used, on the one hand it can make the products more uniform thickness, shrinkage, more in line with design requirements; on the other hand, the resin having a thixotropic precipitated silica product is good, reduce r resin flowing and dripping, reducing waste resin. Protected. Production environment. In the styrene content of 43.5% phthalic unsaturated polyester, 2% of fumed silica thixotropic index of 4.8 can be achieved sales of precipitated silica, the thixotropic index Construction technology already meet domestic gel coat resin. The provisions of the State Bureau of Technical Supervision, hand lay-up glass fiber reinforced gel coat and resin-rich layer of unsaturated polyester resins used in food containers, except for use of fumed silica thixotropic agent shall not join other inorganic fillers. The application of the coating is coating production and consumption country, but the prevalence of current coating suspension stability, thixotropic, weatherability, abrasion resistance and other properties of the problem is poor, resulting in a year to import large quantities of high-grade paint. Join in the paint a little fumed silica, providing anti-caking, anti-sagging, emulsification, extinction, suspension, thickening and thixotropic functions. In the copper-based conductive composite system, the conductive particles are suspended and dispersed in a binder resin, since the relative quality difference between the two (8.9 copper precipitated silicas large companies, the resin is 1.1), the difference in surface properties the conductive particles often tend to precipitate state. Particularly during storage of precipitated silica, the metal particles tend to flocculate and settle to the bottom of the precipitation vessel, severe agglomeration into lumps difficult to disperse, resulting in scrap products. Therefore must join anti-settling agent storage. Conductive powder can greatly limit settlement fumed silica can play a good role in the anti-Shen copper composite conductive system, which amounts up to 1.5%.
