Silicone polyethers, or silicone surfactants, contain both a water-insoluble silicone backbone and a number of water-soluble polyether pendant groups. The ratio of the silicone to polyether, and the molecular weight and composition of the components determine the solubility and specific properties of a product. These products exist as multi-pendant and linear di-functional polymers. Siltech offers a broad range of silicone polyethers as well as custom-designed products for specific applications. These are also available in cosmetic grades, where they are commonly referred to as dimethicone copolyols. These products are widely used as emulsifiers, foaming agents, solubilizers and softeners. They are also used in many inks and coatings formulations were they add slip, mar resistance and leveling.

Siltech offers a series of alkylated silicones co-reacted with polyethers to make them either fully or partially soluble in water. Siltech has the capability of offering any alkylated silicone wax in a water-soluble form. These products are very effective for emulsifying both organic oils and silicones with water.

The Silmer line of reactive silicones consists of both multifunctional and linear-difunctional silicone pre-polymers with reactive terminal end groups. The silicones can be co-reacted into various polymers for coatings, plastics, resins, and other applications to incorporate silicone moiety into a polymer structure. Some basic homologs are offered in each class, but any other homologue can be custom made.

Fluorinated Silicones – Fluorosil Siltech offers a series of fluorinated silicones as well as fluorinated silicones that also contain alkyl or polyether pendant groups. By virtue of the fluorine group, these products offer good solvent resistance, lubricity and slip. The ratio of fluorine and silicone can be varied to suit the customer’s needs.
