| Applications: CN-SI28 The silane can be used alone, after dilution, or as a component of formulated products. Used in natural stone or other building materials, it can form silica sol similar to inorganic substance (SiO2) to enhance the strength of the substrate. CN-SI28 It can be polymerized into silicone resin for varnish or other surface modifiers. CN-SI28 It can be used as sol-gel reaction intermediate. Two-component room temperature vulcanized silicone rubber crosslinking agent. In glass and plastic lens materials, CN-SI28 can provide super-hard anti-scratch coating. | |||
| Precautions: After the container is opened, it should be sealed to prevent water vapor from entering to produce hydrolysis. | |||
