Products

Evonik Modifier 715 is another SiH-terminated polydimethyl siloxane plasticizer for addition-curing silicones. These products do not crosslink but extend the chains of vinyl-terminated silicone polymers (Polymer VS). The use of these modifiers is intended to decrease crosslinking density, resulting in softer elastomers.

Evonik Crosslinker 110, part of the Crosslinker 100 series, consists of polydimethylsiloxanes containing SiH groups within the polymer chain. In addition to SiH groups within the chain, the Crosslinker 100 series features terminal SiH groups. These crosslinkers are essential components of polyaddition silicones. When working with two-component silicone formulations, it is crucial to maintain strict separation between Pt catalysts (e.g., Catalyst 500 series) and SiH crosslinkers to ensure proper performance.

TEGO® Antifoam 2-89 is an antifoam emulsion formulated with organo-modified siloxanes. This product functions as an anti-foaming agent, offering good compatibility with industrial processes. It belongs to the Industrial Additives and Materials category within the Construction Chemicals product family and is specifically tailored for use in cement and concrete additives.

These formulas are used to produce materials that are transparent, free of fillers, and have great mechanical qualities. They can also improve the mechanical properties and flow behavior of systems that are filled.

Evonik Polymer OH 2 is a polydimethyl siloxane with terminal silanol groups, serving as a fundamental component in the formulation of condensation-curing silicone elastomers. This product is offered in a range of viscosity levels, spanning from 100 to 400,000 mPas. In its physical form, it appears clear and colorless. Chemically, it is characterized as hydroxy-terminated polydimethyl siloxanes.

Evonik Polymer VS 500 consists of vinyl-terminated polydimethylsiloxanes available in different viscosity levels and molecular weights, with an impressively low content of volatile constituents. These polymers serve as fundamental components in silicone formulations that cure through a platinum-catalyzed addition reaction with silicone crosslinkers containing SiH groups. The minimal presence of volatile constituents and the crosslinking mechanism ensure that curing shrinkage remains low, and no volatile or corrosive substances are generated during the curing process.

Evonik Modifier 705 refers to SiH-terminated polydimethyl siloxanes utilized as plasticizers in addition-curing silicones. Due to their difunctional structure, these products do not crosslink but extend the chains of vinyl-terminated silicone polymers (Polymer VS). The use of these modifiers reduces crosslinking density and, consequently, the elastomer's hardness.

DYNOL® 604 is a high-performance, non-ionic organic superwetter known for its excellent equilibrium and dynamic surface tension reduction, a hallmark of the Dynol brand. It exhibits lower foam and dynamic surface tension values compared to the more hydrophilic DYNOL® 607 surfactant. Moreover, comparative wetting performance tests have demonstrated that DYNOL® 604 Surfactant serves as an excellent alternative to conventional fluorosurfactants and offers a cost-effective solution in place of new fluorosurfactant technology.

Evonik Polymer VS 100 comprises vinyl-terminated polydimethyl siloxanes available in various viscosity levels and molecular weights, featuring an impressively low content of volatile constituents.
