Silquest™ silane Y-9669 is a versatile adhesion promoter, particularly for resin systems that will react with a secondary amino group, such as isocyanates, acrylates, epoxies, phenolics and RTV silicones. This silane is especially useful when the resulting material must withstand higher temperatures; e.g., in phenolic resin/fiberglass composites.

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-1387 Silane is a Silicone Release Coating.

Silquest™ A-187 silane is specially formulated for use as an adhesion promoter in SPUR + * prepolymer, urethane, epoxy, polysulfide, silicone and acrylic systems for caulks, coatings, sealants and adhesives. Its epoxy functionality allows Silquest™ A-187 silane to perform as a durable epoxy ring that is reactive with many organic functions. It also offers non-yellowing adhesion in many resin systems and has proven to increase the flexibility of systems when compared to other adhesion promoters under certain conditions.

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.

Silquest™ A-178 silane is a coupling agent for glass fiber and particulate filler reinforced composites. It is a 100% active methacrylamido functional silane that may be used to promote adhesion between a wide range of resins and substrates and reinforcements. It is also useful as a monomer in the synthesis of organic polymers. It functions as a moisture- activated crosslinking agent.

Silquest™ A-Link 25 silane and Silquest™ A-Link 35 silane are unique isocyanate functional silanes. The isocyanate functionality exhibits the typical reactivity of an alkyl isocyanate and will react with most active hydrogen containing compounds. The silane portion of these products can then crosslink with each other or be used to adhere to a variety of substrates.
