Properties

Silquest CoatSil 1770 is a clear, colorless liquid with a boiling point of 225-230°C and a density of 1.08 g/cm³ at 25°C. It is soluble in organic solvents like methanol, ethanol, and toluene, and reacts with water to form silanol groups. The molecular formula of the product is C14H28O4Si, and its CAS number is 2386-87-0.

Silquest CoatSil 1770 contains a cycloaliphatic epoxide ring that can undergo ring-opening reactions with various nucleophiles, such as amino, hydroxyl, and carboxyl groups. This functional group provides the product with excellent adhesion, wetting, and coupling properties when used as a surface modifier or crosslinking agent.

Applications

Silquest CoatSil 1770 is widely used in the following applications:

1. Adhesives and Sealants

Silquest CoatSil 1770 can improve the adhesion of silicone, epoxy, and polyurethane adhesives to various substrates like metals, plastics, and glass. It can also enhance the cohesion and flexibility of sealants, resulting in better durability and weather resistance.

2. Coatings and Inks

Silquest CoatSil 1770 can act as a crosslinking agent or coupling agent in coatings and inks based on epoxy, acrylic, and polyester resins. It can improve the wetting, leveling, and scratch resistance of the film, as well as the adhesion to substrates.

3. Composites

Silquest CoatSil 1770 can be used as a coupling agent or crosslinking agent in fiber-reinforced composites based on thermosetting resins like epoxy, polyester, and vinyl ester. It can improve the interfacial adhesion between the fibers and the matrix, resulting in higher mechanical properties and dimensional stability.

4. Plastics and Rubbers

Silquest CoatSil 1770 can modify the surface chemistry of plastic and rubber materials like polypropylene, polyethylene, and EPDM. It can enhance the adhesion to other materials, improve the dispersion of fillers and pigments, and increase the crosslinking density of vulcanized rubbers.
