The carrier system of Deolink silane preparations is specifically developed for each silane grade, used are either polymer/wax systems or pure polymer systems. The comfortable handling of Deolink silane preparations enables the use in open mill mixing as well in in continuous mixing processes. The polymer carrier system protects the silane from ambient moisture. The carrier systems are inert and don’t show any agglomerates
Deolink TESPT Bis([triethoxysilylpropyl]tetrasulfane) is used to improve the physical properties of sulphur cured compounds and to establish the chemical link between rubber and silica or other active white fillers. Mechanical properties, e.g. modulus, compression set, tensile strength and abrasion resistance can be significantly improved by the usage of Deolink TESPT.
Deolink MX is a 50% preparation of thiocarboxysilane on a polymer carrier system. The bifunctional sulphur silane is compatible with all elastomers, which are suitable for sulphur vulcanization. Deolink MX can be used over a broad temperature range and is – at low dumping temperatures – often more active than conventional TESPT. Deolink MX contains a hindered mercapto group and can be used as an alternative to conventional mercaptosilanes. The protective group is
removed during processing releasing the mercaptosilane. By the use of Deolink MX the processing is improved to a higher scorch safety and the typical mercapto odour is avoided. The improved processing leads to higher injection volumes and a better process safety.
