Application
- It can be applied neat, diluted or as part of a formulated product.
- Applied to natural stones or other construction materials, it forms a silica-gel like binder (SiO2) that increases the substrate strength.
- Polymerization of silicone resins for use in paints and other surface modification applications intermediate for sol-gel process.
- For the manufacture of sealant materials RTV-2, it can be used as a cross-linking agent.
- On glass and plastic lens materials, it provides a scratch-resistant, hard-coat to the finish.
