Andisil® 187 Silane

Andisil® 187 Silane by AB Specialty Silicones is epoxy functional silane used as a coupling agent for unsaturated polyester-fiberglass composites and for polysulfide/polyurethane caulks & sealants. It is used as an adhesion promoter in waterborne acrylic sealants. It enhances the wet electrical properties of epoxy-based encapsulate and packaging materials. It eliminates the need for a separate primer in polysulfide and urethane sealants. Andisil® 187 Silane has a shelf life of 2 years.

Andisil® XL

Andisil® XL by AB Specialty Silicones is a series of 11 reactive silicon-hydride-containing polysiloxanes that can be used in addition-cure systems with Andisil VS polymers or Andisil Reactive Methyl Phenyl polymers and an Andisil platinum catalyst. They are available in various viscosities (from 2.5 cSt to 500 cSt) and silicon-hydride contents (from 0.95 mmoles/gm to 8.60 mmoles/gm).

Andisil® MOS

Andisil® MOS by AB Specialty Silicones is a crosslinking agent. It is a liquid raw material used for neutral condensation curing silicone sealants. In the presence of a (tin) catalyst, this silane react with hydroxy-functional silicone polymers. Its exposure to moisture results in the formation of crosslinked, elastomeric silicones. In contrast to acidic or basic curing systems, no acidic acid or amine, but 2-butanone oxime is liberated during application. Due to the neutral character of 2-butanone oxime, sealants based on Andisil® MOS can be applied even on (corrosion) sensitive substrates like metals or marble. It has a shelf life of 1 year.
