Precipitated silica, modified silica, KM-50LS, Hydrophilic
Product Features: 50LS is a structurally modified silica specially developed for unsaturated resins with superior thickening and thixotropic ability. Compared with fumed silica of GM-200, it has similar thickening thixotropic ability, better dispersibility and higher cost performance.A: Obviously high cost performance, compared with fumed silica, with the same thickening thixotropic properties. The cost is only 50--70% of gas silicon!
B: better dispersibility than fumed silica.
C: In the gel coat resin system, the fine pores on the surface can be remarkably reduced.
