Grade: CG-550

3-Aminopropyltriethoxysilane

CG-550 (3-Aminopropyltriethoxysilane) hydrolyzes to form silanol with the release of ethanol, which then condenses with hydroxyl groups on inorganic material surfaces to form Si-O-M bonds. The active amino group (-NH2) can react with various organic functional groups such as carboxylic acids, phenolics, polyesters, and epoxides. It can participate in reactions with various thermosetting, thermoplastic, and elastomeric materials.

Packaging and Storage

This product can be packaged in 25 kg plastic drums, 200 kg plastic drums, or steel drums. Other package sizes are available upon request. Store in a cool, well-ventilated, dry place in tightly sealed containers, protected from light. Keep away from moisture and sources of ignition. Ensure the lid is tightly sealed and effectively isolates the product from air; moisture in the air can react quickly, thereby leading to hydrolysis and polymerization. Shelf life in the original unopened packaging is one year. This product is irritating to skin and eyes. If it contacts skin, wash with soap. If it contacts eyes, rinse immediately with plenty of water.

Application

CG-550 is used in mineral-filled phenolic, polyester, epoxy, PBT, polyamide, polycarbonate and other thermoplastic and thermosetting resins to significantly improve the dry and wet flexural strength, compressive strength, shear strength and other physical-mechanical properties of reinforced plastics, as well as wet electrical properties, while improving the wettability and dispersibility of fillers in polymers.
CG-550 enhances the bonding strength of resin-coated sand in resin sand casting, improving mold strength and moisture resistance.
CG-550 improves moisture resistance and increases compression resilience when added to phenolic binders in the production of glass wool and mineral wool.
CG-550 is an adhesion promoter for polyurethane, epoxy, nitrile, phenolic sealants, improving pigment dispersibility and adhesion to glass, aluminum, and iron metals. It is also suitable for polyurethane, epoxy, and acrylic latex coatings.
CG-550 helps improve the phenolic bonding and water resistance of self-hardening abrasives in grinding wheel manufacturing.
