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®-PS
The unique string-of-pearl particles and high viscosity of SNOWTEX-PS give it excellent bonding and coating properties. That, in conjunction with its high fluidity, make SNOWTEX-PS excellent for:
Coating paper, plastics and metals
Binder for catalyst
Modification of paints and coating agents
Fiber treatment
Binding agent
Casting
Colloidal silica solution in water. Used in industrial applications such as coating for paper, plastics and metals and for modification of paints. Possesses string-of-pearl particles and high viscosity. Gives very good bonding and coating properties and high fluidity.
