Applications
1. RTV Silicones and Hybrid Silane-Crosslinked Sealants
TB-681 can dramatically enhance adhesion to a wide array of plastics when used in combination with SPIRSM Technology for silylating urethane polymers.
2. Plastisol Sealants
Addling silane TB-681 as a replacement for polyaminoamide adhesion promoters in plastisol sealants improves bonding to metal substrates.
3. Additive in Phenolic and Epoxy Molding Compounds
Silane TB-681, as an additive in phenolic and epoxy molding compounds, reduces the water absorption of molded composites.
