Properties:
ELT-540 is a methacryl-functional silane; it is a clear, light and heat sensitive liquid with a faintly sweet odour.
ELT-540 is used as adhesion promoter at organic/inorgainc interfaces, as surface modifier (e.g. imparting water repellency, organophilic surface adjustment) or as crosslinking of polymers).
It is used as a coupling agent to improve the physical and electrical properties of glass-reinforced and mineral-filled thermosetting resins under exposure to heat and/or moisture.
It is typically employed as a blend additive in resin systems that cure via a free radical mechanism (e.g. polyester, acrylic) and in filled or reinforced thermoplastic polymers, including polyolefins and polyurethanes.
It is also used to functionalize resins via radical initiated processes-copolymerization or grafting - and to modify surfaces.
Reactivity:
ELT-540 is soluble in methanol, ethanol, isopropanol, acetone, benzene, toluene, and xylene. After hydrolysis, it is soluble in water with adequate stirring if the pH is adjusted to 4.0. Hydrolysis releases methanol.
ELT-540 shows copolymerization or grafting reactions when catalyzed by (organic) initiator systems, e.g. peroxides or by radiation (e.g. UV).
Application and performance:
ELT-540 can improve strength as glass fiber size composite in reinforced polyester composites.
ELT-540 can enhance initial and wet strength of reinforced polyester resin composites.
ELT-540 can enhance the wet electrical properties of many mineral-filled and reinforced composites.
ELT-540 crosslinked acrylic type resins can improve adhesion and durability of adhesives and coatings.
Packing & storage:
