The silane portion of these products can then crosslink with each other or be used to adhere to a variety of substrates.

Silquest™ A-189 silane chemically bonds reinforcing minerals such as silica, clay, mica and talc to the polymer matrix. This silane is especially useful in sulfur-cured and metal oxide-cured elastomers. It can be used as a pretreatment on minerals or added at the time of compounding.Improvement in mineral-filled elastomer properties, including modulus, tensile and tear strength, heat buildup, abrasion resistance, resilience, compression set and cure time may be achieved with Silquest™ A-189 silane (gamma-mercaptopropyltrimethoxysilane).

Silquest™ A-Link 15 silane may be used for use as an endcapper or crosslinker for isocyanate functional prepolymer systems. This product provides improved thermal and UV stability over previous secondary amino silane endcappers. Silquest™ A-Link 15 silane can also be utilized as an adhesion promoter in silicone, hybrid, urethane, and epoxy adhesives and sealants.

Silquest™ Y-11699 silanes are secondary aminofunctional bis-silanes. This category of silanes is generally useful to consider for a broad range of applications to promote adhesion in coatings, adhesives and sealants between organic polymers and glass, metal, wood or cast plastic substrates.

Silquest™ A-1106 silane is an aqueous solution of an aminoalkyl siloxane. This alcohol-free siloxane improves signifi- cantly the adhesion and coupling between organic resins and inorganic surfaces. Momentive Performance Materials Silquest™ A-1106 silane is most often used in aqueous systems where the alcohol of hydrolysis causes instability of the formulation or where a high flash point additive is required. The product also reduces volatile organic content (VOC) and does not contain hazardous air polluting substances (HAPS). These benefits are particularly useful to manufacturers seeking to reduce emissions from their water-borne products and processes.

CoatOSil™ 1770 silane can benefit from better adhesion, improved appearance, and longer retention of functional and esthetic properties. As a cycloaliphatic epoxy silane, CoatOSil™ 1770 silane can deliver crosslinking in latex under room or elevated temperature cure conditions. Through crosslinking, CoatOSil™ 1770 silane can improve the solvent, stain and weather resistance of the final coating.

Silquest™ A-1871 Epoxy Silane is a gamma-Glycidoxypropyltriethoxysilane. Acts as adhesion promoter. This epoxy functional silane provides outstanding chemical resistance, mechanical properties, improved adhesion to glass and metal substrates. It also provides crosslinking of waterborne latexes and dispersions; acrylic, styrene acrylic or other copolymers, polyurethane or epoxy dispersions. Has enhanced electrical properties of epoxy based electronic encapsulants and packaging materials, resulting from improved bonding between resin, substrate or filler. Improved wet adhesion reduces the risk of semiconductor or integrated circuit failure as a result of water ingress or surface corrosion. It also has improved dry adhesion and tensile strength. Use of epoxy silane may avoid the yellowing sometimes seen when amino functional adhesion promoters are used and it also has improved shelf stability over aminosilane alternatives. It is used in caulking applications.

Silquest™ A-1170 is a Amino bis-silanes can be effective in reacting with epoxy, urethane, melamine, polyimide, phenolic and furan thermosetting resins, as well as many thermoplastics, such as polyamides and polyesters. Silquest™ A-1170 silane offers a fast cure time and/or rapid adhesion build. Because of its higher purity grade, Silquest™ A-1170 silane is an excellent candidate to consider for use in applications that demand low color and greater control of reaction stoichiometry. Silquest™ A-1170 silane is a versatile silane, and it may be added directly to polymers during system formulation or used independently as a primer.

Silquest™ Y-9627 is secondary aminofunctional bis-silanes. This category of silanes is generally useful to consider for a broad range of applications to promote adhesion in coatings, adhesives and sealants between organic polymers and glass, metal, wood or cast plastic substrates. Typically, they can function as coupling agents to particulate mineral fillers in composites, as in foundry molds and cores, to improve mechanical properties such as tensile and flexural strengths. These property improvements have been maintained in the presence of aggressive environments, such as high temperature and high humidity conditions.

Silquest™ A-151 silane (vinyltriethoxysilane) is a general-purpose coupling agent used with mineral-filled polyolefin and elastomeric compounds.
