Deolink® Liquid Silanes

Silanes enable inorganic fillers to be chemically coupled with elastomers. Without the use of silanes, only fairly week physical bonds can beformed, e.g. Van-der-Waals-forces, adhesion or absorption. The chemical process of silanization improves the final product. Predominantly silica, clay, quartz, ATH and – to a lesser extent – also talc, mica, and inorganic oxides such as TiO2 are commonly used as light filler in silanization processes. In addition to the standard sulphur - and vinylsilanes, DOG also offers a range of silane specialties for various applications.

Deolink TESPT-100

Deolink TESPT-100 [Bis(triethoxysilylpropyl)tetrasulfane] is the most common silane in the rubber industry, used for various applications and sulphur vulcanization processes. The reactivity of the silanization depends on the temperature of the process. For the use of Deolink TESPT-100, a mixing / dumping temperature of 130 – 150 º C is recommended.

Deolink MX-100

Deolink MX-100 [Thiocarboxylsilane] is also a bifunctional sulphur silane, suitable for all elastomers which can be cross-linked with sulphur. Deolink MX-100 can be used over a broad temperature range. At low dumping temperatures, Deolink MX-100 is often more efficient than the conventional TESPT. Deolink MX-100 contains a hindered mercapto group and can be used as an alternative to conventional mercaptosilanes.

The protective group is removed during processing, releasing a mercaptosilane. When using Deolink MX-100, the processing is improved by increasing the protection against scorch and preventing the typical mercaptane odour. Deolink MX-100 is substantially less scorchy than conventional mercapto- or sulphur silanes. An advantage of this property is that higher injection volumes and improved scorch safety can be achieved.

Deolink Vinyl-100 / Deolink Vinyl TE-100

Deolink Vinyl-100 (Tris[2-methoxyethoxy]vinylsilane) and Deolink Vinyl TE-100 (Triethoxyvinylsilane) are used to improve the physical properties of peroxide cured compounds and to establish a chemical link between rubber and light active filler. By the use of Deolink Vinyl-100 and Deolink Vinyl TE-100, the wet electrical properties can be optimized, which is of relevance for the cable industry. Deolink Vinyl TE-100, as opposed to Deolink Vinyl-100, does not develop toxic methoxyethanol during processing.

Deolink Amino TE-100

Deolink Amino TE-100 (3-Aminopropyltriethoxysilane) is a very reactive type of silane and can be used in sulphur-free crosslinking systems. Aminosilanes are used in acrylate compounds with light active filler and improve the compression set and physical properties. Additional areas of application for Deolink Amino TE-100 include flame retardant compounds for the cable industry based on EVA and ATH.

Deolink Methacryl TM-100

Deolink Methacryl TM-100 (Methacryloxypropyltrimethoxysilane) can be used for sulphur and sulphur-free vulcanization systems. Deolink Methacryl TM-100 improves the processing of the rubber compound as well as mechanical properties of the vulcanizates.
