GC9007 Silane


It is a versatile amino-functional coupling agent used over a board range of applications to provide superior bonds between inorganic substrates and organic polymers. The silicon-containing portion of the molecule provides strong bonding to substrates. The primary amine function reacts with a wide array of thermoset, thermoplastic, and elastomeric materials.

GC9007 is completely and immediately soluble in water(with reaction), alcohol, and aromatic and aliphatic hydrocarbons. Ketones are not recommended as diluents.


Silane Couping Agent GC9007 is applied in plastic products(including cables, glassfiber-reinforcement plastics etc.), rubber products, adhesives, coatings, pigments dispersion, inks, magnetic materials(plastic magnet and rubber magnet), metallic casting resins and resins concrete, etc.

·GC9007 maximizes the physical and electrical properties of mineral-filled phenolics, epoxies polyamides, polybutylene terephthalate, and a host of other thermoset and thermoplastic composites. Filler wetting and dispersibility in the polymer matrix are also improved.

·GC9007 improves adhesion between magnetic powder and organic resins and dispersion of magnetic powder inorganic resins. Also these magnetic appliances attain higher magnetic orientation and excellent magnetic properties, higher mechanical strength, good processability, excellent weathering resistance.

·In glass-reinforced thermoset plastics, GC9007 enhances the flexural, compressive, and interlaminar shear strengths before and after exposure to humidity.
GC9007greatly improves wet electrical properties.

·With nitrile, polysulfide, expoxy, urethane, and adhesives and sealants,GC9007
improves pigment dispersion and maximizes adhesion to glass, aluminum, and steel.

·When GC9007 is used, glass-reinforced thermoplastics, polyamides, polyesters, and polycarbonates exhibit increased flexural and tensile strengths before and after wet exposure.

·In glass fiber and mineral wool insulation, as a phenolics resin binder additive, GC9007 imparts moisture resistance and allows recovery after compression.

·In shell molding foundry applications,GC9007 strengthens the bond between the phenolics binder and foundry sand.

·In grinding wheels,GC9007 promotes an improved, water-resistant bond between the abrasive frit and phenolics resin binder.

·GC9007 is an excellent adhesion prompter in urethane, epoxy, and acrylic latex coatings, adhesives, and sealants.
