1. GX-550 is is an excellent adhesion promoter used in acrylic coatings, adhesives and sealants.
2. Used in glass fiber reinforced thermosetting and thermoplastic plastics, aminosilane GX-550 can greatly improve the bending strength, tensile strength and interlaminar shear strength in dry and wet conditions, and significantly improve the wet electrical properties.
3. Adding it to the phenolic resin adhesive can improve the moisture resistance and resilience after compression.

4. This product can greatly improve the physical and mechanical properties and electrical properties of phenolic resin, polyester resin, epoxy, polyamine, polycarbonate and other thermoplastic and thermosetting resins filled with inorganic fillers, and improve the wettability of fillers in polymers And dispersion.

5. The use of this product can reduce the amount of phenolic resin or furan resin bonding agent in the silica sand casting mold, and increase the strength of the molding sand and reduce the amount of gas generation.
