Â©¶· >> ¹èÍÁ Filler >> Silica water SNOWTEX® is a colloidal silica with many applications for paper, fibers, steel and catalysts. Most recently, it has been used by the semiconductor industry as a polishing agent for silicon wafers. Without the development of chemicals such as SNOWTEX, the electronics industry would not be where it is today. SNOWTEX® has a wide variety of industrial applications such as: Adhesion and coating Particles and Surface State SNOWTEX® is a colloidal silica solution made by dispersing negatively charged, amorphous silica particles in water. The particles are spherical in shape. OH ions exist at the surface of the particles with an electric double layer formed by alkali ions. Stabilization is achieved by the repulsion between the same negatively charged particles. Disturbance of the charge balance will cause the colloidal silica to aggregate, resulting in high viscosity or gelation of the solution. Properties of SNOWTEX®-UP The colloidal particle of SNOWTEX-UP has a unique, elongated shape unlike typical, spherical silicasol. SNOWTEX-UP has many advantages. The elongated particle shape and high viscosity of SNOWTEX-UP give it excellent properties for film forming, bonding and less migration. This can be useful for: Coating paper, plastics and metals Binder for refractories Binder for ceramics, glass and fiber Textile treatment Colloidal silica solution in water. Used in industrial applications such as coating for paper, plastics and metal. Possesses elongated particles and high viscosity. Offers very good properties for film forming, bonding and less migration.
