Silquest™ A-171 silane offers vinyl and silane functionality and also can be utilized for chain extension of RTV silicones or OH functional polymers. This results in Si-O-Si crosslink sites that are highly resistant to the effects of exposure to moisture, chemicals and UV rays. As a siloxane crosslinker, Silquest™ A-171 silane typically does not generate color and is resistant to acid rain under most conditions. This silane is also useful as a moisture scavenger in moisture cure systems where improved shelf life is desired.

Silquest™ VS 142 Silane is a high purity, amino-alkyl-silane solution in water, and as such provides the performance of aminoalkylsilane esters such as Silquest™* A-1100 Silane, in a convenient prehydrolyzed form. Silquest™ VS 142 silane can be easily diluted with water and does not contain alcohol. and Resilency.

Silquest™ VX-225 silane is an amino-functional oligosiloxane adhesion promoter that may be considered for use over a broad range of adhesives and sealants applications.

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-137 silane is a monomeric alkylalkoxysilane that, when exposed to moisture, is reactive with minerals contained in concrete, masonry and other substrates. The monomer can penetrate deeply into a substrate, and then react to form an extremely durable protective surface surrounding each microscopic particle.

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.
