Industrial Applications of 13731-98-1
| Industry | Application | Process |
|---|---|---|
| Coatings & Inks | Used as an adhesion promoter to enhance coating adhesion to inorganic substrates such as glass, metals, and ceramics | Incorporated into acrylic, epoxy, or polyurethane systems via copolymerization or surface treatment |
| Composites | Applied as a coupling agent for inorganic fillers such as glass fiber and mineral fillers to improve interfacial bonding with organic resin matrices | Hydrolysis and condensation reactions performed during filler pre-treatment to form siloxane-bonded layers |
| Adhesives | Enhances adhesive strength and resistance to moisture/heat aging of structural adhesives or sealants on low-energy substrates | Added directly as a functional monomer into adhesive formulations to participate in crosslinking during cure |
| Dental Materials | Used in dental composites and bonding agents to improve compatibility between inorganic fillers (e.g., silica) and organic matrices | Copolymerized with methacrylate monomers to form organic-inorganic hybrid networks |
| Electronic Encapsulation | Improves interfacial bond strength between encapsulants and substrates such as silicon wafers and metal lead frames | Added as an additive to epoxy molding compounds or underfill materials, forming covalent bonds during thermal curing |
Manufacturing Quality Control of 13731-98-1
| Detection Item | Common Analytical Method | Method Overview |
