Applications

    1. Used in mineral-filled thermoplastic and thermosetting resins such as phenolic, polyester, epoxy, PBT, polyamide, carbonate, etc. It can greatly improve physical and mechanical properties (dry and wet flexural strength, compressive strength, shear strength) and wet electrical properties of reinforced plastics, and improve the wettability and dispersion of fillers in polymers.

    2. Excellent adhesion promoter, applicable to polyurethane, epoxy, nitrile, phenolic adhesives and sealing materials. Improves pigment dispersion and adhesion to glass, aluminum, iron and other metals. Also suitable for polyurethane, epoxy and acrylic latex coatings.

    3. In resin sand casting, it enhances the adhesion of resin silica sand, improves the strength and moisture resistance of molding sand. In the production of glass wool and mineral wool, adding it to phenolic adhesives improves moisture resistance and compressive resilience.

    4. In grinding wheel manufacturing, it helps to improve the adhesion and water resistance of phenolic binders for wear-resistant self-hardening sand.

Storage & Transportation:

This product should be tightly sealed and stored in a dry, cool, dark indoor place.
