Momentive SILQUEST A-1524 (γ-ureidopropyltrimethoxysilane) is a 100% active silane coupling agent engineered to enhance adhesion between resins (epoxy, polyurethane) and inorganic substrates (glass, metals). It improves mechanical strength, chemical resistance, and filler dispersion in composites, coatings, and sealants. With rapid hydrolysis and curing at ambient temperatures, it is ideal for fiber-reinforced plastics and corrosion-resistant coatings, complying with REACH standards for sustainable industrial use
Dual Reactivity - Ureido groups bond with polymers; methoxy links to fillers/metals
Process Stability - Longer pot life than aminosilanes in reactive systems (epoxy, phenolic)
Non-Yellowing - Resists UV/heat-induced discoloration, ideal for clear coatings
Eco-Efficiency - Solvent-free, low VOC (<50 g/L), halogen-free
Fiberglass Sizing - Enhances wet strength in FRP composites
Metal Primers - Improves adhesion to oily metals in automotive coatings
Sealants - Polyurethane formulations with extended shelf life
Foundry Resins - Boosts sand core strength in casting applications
