Momentive SILQUEST A-1524 Silane Coupling Agent

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

Features Of Momentive SILQUEST A-1524 Silane Coupling Agent

  1. Dual Reactivity - Ureido groups bond with polymers; methoxy links to fillers/metals

  2. Process Stability - Longer pot life than aminosilanes in reactive systems (epoxy, phenolic)

  3. Non-Yellowing - Resists UV/heat-induced discoloration, ideal for clear coatings

  4. Eco-Efficiency - Solvent-free, low VOC (<50 g/L), halogen-free

Typical Applications Of Momentive SILQUEST A-1524 Silane Coupling Agent

  1. Fiberglass Sizing - Enhances wet strength in FRP composites

  2. Metal Primers - Improves adhesion to oily metals in automotive coatings

  3. Sealants - Polyurethane formulations with extended shelf life

  4. Foundry Resins - Boosts sand core strength in casting applications
