Silquest A-1524 Silane gamma-ureidopropyltrimethoxysilane, Crompton-OSI Specialties Adhesion Promoters >> Organofunctional silane Epoxy (EP) Aminoplaste & Phenoplastes (UF, MUF...) PU - Prepolymers ADHESIVE SEALANT Gamma-Ureidopropyltrimethoxysilane, is a 100-percent active ureidosilane that may be used to promote adhesion between a wide range of resins and substrates, fillers or reinforcements. 100% Active Ingredient Contains no flammable or combustible solvent Contains no alcoholic solvent diluent, making it suitable for use in reactive polymer systems such as isocyanate-terminated polyurethane polymers Offers low VOC emissions. Methoxysilane Ester Rapid attainment of bond strength Fast hydrolysis of silane ester group in resin systems Good water solubility. Ureidofunctional Group Longer pot life (stability) than aminosilanes in reactive polymer systems such as phenolic, epoxy, urea-melamine or polyurethane Does not generate color with time and aging Provides nitrogen reactivity without the strong basic characteristics of typical aminosilanes Exhibits excellent urethane adhesive and sealant adhesion to oily metals. 100-percent active ureidosilane used to promote adhesion between a wide range of resins and substrates, fillers or reinforcements. Contains no flammable or combustible solvent. Exhibits very good urethane adhesive and sealant adhesion to oily metals.
