OH Polymer - MESIL 107 Series

MESIL® OH polymer is a range of silanol functional fluids available in a variety of viscosity and silanol contents. They can be used to treat fillers and as anti-structuring additives in sealants and adhesives formulations. Low viscosity grades can be used as reactive diluents for higher viscosity polymers to adjust the overall viscosity of the formulation.

Most of our customers are in the silicone sealant and adhesives industries, which produces a variety of silicone sealants for use in insulating glass, household or construction industries.

APPLICATIONS

Can be widely used in electronics, semiconductors, automobiles, machinery, textiles, plastics, printing, construction and other fields.

Condensation cure one-part and two-part RTV systems are formulated from silanol terminated polymers with molecular weights ranging from 15,000 to 150,000. One-part systems are the most widely used. One-part systems are crosslinked with moisture-sensitive multi-functional silanes in a two stage reaction. In the first stage, after compounding with fillers, the silanol is reacted with an excess of multi-functional silane. The silanol is in essence displaced by the silane.

The reactivity of silanol fluids is utilized in applications other than RTV. Low viscosity silanol fluids are employed as filler treatments and structure control additives in silicone rubber compounding. Intermediate viscosity, 1000-10,000 cSt. fluids can be applied to textiles as durable fabric softeners. High viscosity silanol terminated fluids form the matrix component in tackifiers and pressure sensitive adhesives.
