SF-Si28 silane can be used alone, diluted, or used as a component in formulated products. Used in natural stone or other building materials, silica sol can be formed similar to inorganic substances (SiO2) to enhance the strength of the substrate.
SF-Si28 can be polymerized and reacted into silicone resins for use in varnishes or other surface modifiers.
SF-Si28 can be used as a sol-gel reaction intermediate. Two component room temperature vulcanized silicone rubber crosslinker. SF-Si28 provides a super hard scratch resistant coating for glass and plastic lens materials
