Main use
1. Coupling agent 550 is an excellent glass fiber treatment agent, which improves the mechanical strength, electrical properties and aging resistance of the composite. In the production of glass fiber wool and mineral wool, it can be added to phenolic resin binder to improve moisture resistance and increase compression resilience. It can also be used for the synthesis of amino silicone oil and its emulsion..
2, coupling agent 550 used in mineral filled phenolic, polyester, epoxy, PBT, polyamide, carbonate and other thermoplastic and thermosetting resins, can greatly improve, enhance the plastic dry and wet bending strength, compressive strength, shear strength and other physical and mechanical properties and wet electrical properties, and improve the wettability and dispersion of fillers in polymers.
3. Coupling agent 550 is an excellent adhesion promoter, which can be used for polyurethane, epoxy, nitrile, phenolic adhesives and sealing materials, can improve the dispersion of pigments and improve the adhesion to glass, aluminum, iron and metal, and is also suitable for polyurethane, epoxy and acrylic latex coatings.
4. Coupling agent 550 helps to improve the phenolic resin bonding and water resistance of wear-resistant self-hardening sand in the manufacture of grinding wheels.
Storage and transportation matters
Coupling agent 550 is packed in plastic drum and carton, sealed at room temperature, valid for one year.
