Applications

1. Resin Composites

   Used in mineral-filled phenolic, polyester, epoxy, PBT, polyamide, carbonate and other thermoplastic / thermosetting resins. Greatly improves dry/wet flexural strength, compressive strength, shear strength and wet electrical properties of reinforced plastics, and enhances filler wettability and dispersion.
2. Resin Sand Casting

   Strengthens bonding between resin and silica sand, improves molding sand strength and moisture resistance.
3. Fiber Glass & Mineral Wool

   Added to phenolic adhesives to improve moisture resistance and compression resilience.
4. Adhesives & Sealants

   Excellent adhesion promoter for polyurethane, epoxy, nitrile, phenolic adhesives and sealants. Improves pigment dispersion and adhesion to glass, aluminum and iron.
5. Coatings

   Suitable for polyurethane, epoxy and acrylic latex coatings.
6. Organosilicon Synthesis

   Used in the synthesis of amino silicone oil and its emulsions.
