CoatOSil™ MP 200 silane promotes adhesion in a broad range of applications via multiple epoxy and silane groups on each oligomer chain. Its gamma-gylcidoxy propyl epoxide ring reacts with many organic groups while its alkoxy silane groups promote adhesion to inorganic substrates. Condensation of its silanol groups can also provide crosslinks between polymer chains.

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.

Enhancing the physical properties of water-borne dispersion polymers, such as polyurethane and acrylic latexes, CoatOSil™ 2287 silane enables the formulation of coatings with good shelf stability, improved wet adhesion and enhanced resistance to water and organic solvents. This non-yellowing additive can be considered as an adhesion promoter or crosslinker.

Silquest™ A-186 silane adhesion promoter, can result in better electrical and/or mechanical properties in a variety of applications and industries. From enhancing electronic encapsulants to enabling improved sealant formulations, Silquest™ A-186 silane provides both epoxy and silane functionalities that promote adhesion in a range of formulations, including SPUR+ prepolymer, urethane, epoxy, silicone, and acrylic caulks, coatings, sealants and adhesives.

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.

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-174NT silane is a momentive performance materials, methacryloxy functional trimethoxy silane that finds utility in coating, composite and adhesive and sealant systems that cure via a free radical mechanism.

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.

SPUR+™ 1050 prepolymer is a silylated prepolymer, plasticizer-free, with low viscosity, for use in the manufacture of one-part, moisture-curing sealants. It is an excellent material of choice as a base resin for medium modulus sealants and adhesives in industrial and transportation applications where higher tensile strength is required.

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.

SPUR+™ 1015 prepolymer is a silylated polyurethane resin for manufacturing one-part, moisture-curing sealants and adhesives. Plasticizer-free and of relatively low viscosity, it is an excellent base resin for low modulus sealants in building and construction applications where good elastic recovery is required.

Silquest™ A-151 silane (vinyltriethoxysilane) is a general-purpose coupling agent used with mineral-filled polyolefin and elastomeric compounds. Silquest™ A-151 silane can be added as a monomer during emulsion polymerization to form silane-modified latexes that function as crosslinkers, forming very stable Si-O-Si linkages.

Silquest™ A-Link 599 silane is a thiocarboxylate functional silane adhesion promoter that has low odor, low volatility and low mercapto reactivity until the thiocarboxylate is activated during application of the adhesive or sealant. Silquest™ A-Link 599 silane is a blocked mercaptosilane, wherein the octanoyl group blocks the sulfurfunctional part of the molecule. The octanoyl group gives improved solubility in many resin systems. It eliminates the usual mercapto odor during formulation, storage and initial application of a sealant. It further prevents the reaction or deactivation of the mercap- to group with tin and platinum catalysts. Finally, in the sealant application step, the octanoyl-blocking group hydrolyzes to give a reactive mercaptosilane that bonds between the resin and substrate.

SPUR+™ 1012 prepolymer is a silylated prepolymer that does not rely on an isocyanate curing reactions. Additionally, it is formulated without the use of phthalate-based plasticizers, and in sealant formulations, using it as the base resin or in combination with SPUR+™ 1015 prepolymer, extremely low modulus values can be attained. This moisture curable resin is an excellent candidate to consider in formulating construction sealants requiring rapid cure, good water resistance, high flexibility and adhesion to most construction substrate materials such as concrete, marble and glass. SPUR+™ 1012 prepolymer can help enable the formulation of non-staining, paintable sealants.

SPUR+™ 1060 prepolymer is a plasticizer-free, ethoxysilane-modified resin used in the manufacture of one-part moisture-curing adhesives and sealants. It is an excellent material of choice as a base resin for medium modulus adhesives and sealants that serve a range of applications, particularly where HAPs emissions are a significant factor.
