Name: Momentive Silquest A-174NT Gamma-Methacryloxypropyltrimethoxysilane
Brand: Guangzhou Eric Wei Chemical Co., Ltd.

Features Of Momentive Silquest A-174NT Gamma-Methacryloxypropyltrimethoxysilane

Reactive dual functionality: methacrylate group enables covalent bonding with acrylic, polyester, and vinyl monomers; hydrolyzable methoxy groups provide strong adhesion to inorganic substrates.
Enhanced hydrolytic stability versus conventional alkoxysilanes due to optimized molecular structure and controlled impurity profile.
Low volatility and improved handling safety—designed for industrial-scale compounding and coating formulations without excessive vapor pressure concerns.
Consistent batch-to-batch performance validated through rigorous QC testing per ISO 9001-compliant manufacturing standards.
Enables superior interfacial coupling in filled composites, significantly improving mechanical strength, moisture resistance, and long-term durability.

Typical Applications Of Momentive Silquest A-174NT Gamma-Methacryloxypropyltrimethoxysilane

Adhesion promoter in UV-curable coatings and inks for glass, metal, and plastic substrates.
Surface modifier for silica, glass fibers, and mineral fillers in high-performance thermoset composites (e.g., epoxy, unsaturated polyester).
Coupling agent in dental restorative resins and orthodontic adhesives to enhance filler–matrix bonding.
Key ingredient in solvent-free and low-VOC sealants and structural adhesives requiring robust substrate adhesion.
Functional additive in radiation-cured pressure-sensitive adhesives (PSAs) to improve cohesion and substrate anchoring.
