Applications
1. RTV Silicones and Hybrid Silane-Crosslinked Sealants
Silane TB-501 provides enhanced adhesion performance without negatively impacting elongation.
2. Polysulfide Sealants
When added to one-and two-part polysulfide sealants, silane TB-501 provides better adhesion to a variety of substrates, including glass, aluminum and steel.
3. Plastisol Sealants
Adding silane TB-501 as a replacement for polyaminoamide adhesion promoters in plastisol sealants improves bonding on metal substrates.
4. Additive in Phenolic and Epoxy Molding Compounds
TB-501, as an additive in phenolic and epoxy molding compounds, reduces the water absorption of molded composites.
