BRB Silanil® 829 is a bi-functional organosilane with broad application possibilities. Due to its versatile structure, which combine six hydrolysable groups with a secondary amine group, it can function as an excellent crosslinker while also providing a good stability in applications such as encapsulating urethane prepolymers. BRB Silanil® 829 is specified by CAS number 82985-35-1.
BRB Silanil® 829 is well-suited for adhesion promotion, functioning as a coupling agent between organic and
inorganic substances, and in certain applications, it also contributes to mechanical properties, e.g. in furan or
phenolic foundry mould
making.
Key applications of BRB Silanil® 829 include:
• Adhesion promoter for systems based on, for example, polyurethane, epoxy, phenolic, furan, melamine, acrylic,
silicone, PVB, EVA, PBT, PVAc, PVC, polyamide, polyimide, and other organic resins containing functional groups on
inorganic substrates such as glass, aluminum, and
metal.
• Coupling agent for fiberglass-reinforced composites to improve mechanical properties
• Mineral filler treatment.
