Silquest Y-11637 Silane Aminosilane Crompton-OSI Specialties Adhesion Promoters >> Organofunctional silane Epoxy (EP) Silicones (Si) PU - Prepolymers SEALANT ADHESIVE Silquest® Y-11637 Silane OSi Specialties Product Description: Silquest® Y-11637 silane is a non-yellowing adhesion promoter that can provide sealants and adhesives with good flexibility and superior adhesion compared to other aminosilanes. It is a primary aminosilane and is recommended for silicone, urethane, epoxy, silylated polyether and polyurethane adhesives and sealants. Silquest Y-11637 improves color stability and reduces yellowing versus other aminosilanes, providing excellent adhesion to both organic and inorganic substrates. It also improves sealant flexibility and elastic recovery, while enhancing the performance o low modulus sealants during joint expansion. Non-yellowing primary aminosilane. Used as an adhesion promoter for silicone, urethane, epoxy, silylated polyether and polyurethane adhesives and sealants. Improves color stability and reduces yellowing. Provides good flexibility and very good adhesion to both organic and inorganic substrates. Enhances performance of low modulus sealants during joint expansion.
