Characters & Applications:
GX-670 Silane is a new type of coupling agent with reactivity. 
1. Used in the treatment of glass fiber. It can enhance  the flexural, compressive and interlaminar shear strengths and  makes a firmer bond.
2. Used in coatings and ink. It can improve radiancy and Film hardness.
3. Used in electrical wire and cable, it can greatly improve its mechanical performance and electrical performance in wet state.
Usage
1, this product is suitable for a variety of complex shapes, all densities of polyethylene and copolymers; for larger processing tolerance, filled composite materials, etc., with a high operating temperature, excellent resistance to pressure cracking, abrasion and impact resistance; can be grafted to the main chain of the polymer so as to modify the polymer, such as polyethylene and other polymers, so that the side chain with the product's ester group as the active point of the warm-water cross-linking.
2, Used in glass fiber can effectively improve the mechanical properties of glass fiber products (bending strength, tensile strength, etc.) and the adhesion of the substrate (a variety of resins, including thermosetting and thermoplastic, etc.).
3, used as an additive for inks and coatings after the ink, coating film can be made to have excellent film hardness and brightness; to improve the adhesion of the fiber optic coatings.
4, as a reinforcing agent and cross-linking accelerator is widely used in composites, coatings, ink As a reinforcing agent and cross-linking promoter, it is widely used in composites, coatings, inks, Chemicalbook glues, and sealing materials, etc. It can also be used as resin modification additives and enzyme fixing agents.
5. As a cross-linking agent, it can be used in silane cross-linking of polyethylene cables and tubes; for the wire and cable industry, it is used in the treatment of the clay-filled, peroxide-cross-linking EPDM system with this coupling agent, which improves the depletion factor and specific inductance tolerance and resistance.
6. Copolymerization with vinyl acetate and acrylic or methacrylic monomers, these polymers are widely used in coatings, adhesives and sealants to provide excellent adhesion and durability.
Applications and Properties
1,Improve the strength when glass fiber synthesized in reinforced polyester composites.
2,Improve the initial and wet strength of reinforced polyester resin composites synthesized in marble.
3,Improve the mineral filling and enhance the wet electrical properties of composites.
4,Cross-linking fishy acrylic resins to improve the adhesion and durability of the adhesive and coatings.
