Name : Deolink MXDescription : Activator for fillerActive substances : Organoalkoxy-silaneSilane content (%) : 50Appearance : white pelletsAnalytical valuesTotal sulphur ASTM D 1552 (LECO) : 3.8 - 4.8Dropping point (oC), Mettler-apparatus DIN ISO 2176 :  105 - 115Density at 20oC (g/cm3) DIN ISO 787 part 10A : 1.0Dosage : in relation to silica-filler (%) : 1 - 8German Food Legislation (BfR recommendation XXI) : not approvedSupply Form : 20 kg in cardboard boxes with PE-inliner,spezial packaging available on requestStorage StabilityIn originally sealed package in cool and dry places : min. 12 monthsClassification and LabellingDeolink MX is labelled as "irritant" (Xi) according to EEC directives. For more detailed information, please refer to our Material Safety Data Sheet.Behaviour and EffectsDeolink MX is an alternative to mercaptosilanes which often cannot be used because of their unpleasant smell. The mercaptosilane present in Deolink MX is set free from the carrier during the mixing process. Because of its bifunctionallity it forms a chemical bond between the rubber molecule and the silica filler at cure temperature.ApplicationDeolink MX is best dosed into the internal mixer together with the filler at elevated temperatures of about 120 - 160 oC to improve the physical properties of compounds with white fillers crosslinked by sulphur.The incorporation in a PE-wax enables an optimal protection of the active silane against humidity.Name : Deolink TESPTDescription : Activator for fillerComposition : Bis(3 - trithoxysilylproplyl)tetrasulfane (TESPT), 50 % i EVA/wax carrierAppearance : Yellow pelletsAnalytical valuesTotal sulphur (%) ASTM D 1552 (LECO) : 10 -13Density at 20oC(g/cm3) DIN ISO 787 part 10A : 1.0 Dropping point (oC),Mettler-apparatus Din ISO 2176 : 72 5Dosage : approx. 10%, in relation to silica-fillerSupply Form : 20 kg in cardboard boxes with PE-inlinerStorage StabilityIn originally sealed package, in cool and dry places : min. 1 yearBehaviour and EffectsDue to its bifunctionality Deolink TESPT links through the tetrasulfane group to the rubber molecule and through the ethoxy group to the silanol groups of the filler. The chemical bond between polymer and filler improves the physical properties of the vulcanizate.ApplicationDeolink TESPT is used to improve tensile strength, modulus an abrasion of the vulcanizates from all commmonly used elastomers. Deolink TESPT should be dosed into the internal mixer together with the filler. Best results are obtained at elevated temperatures at about 120-140 oC. Mainly for compounds crosslinked by suplhur. Due to the incorporation into an EVA-wax-matrix the silane is optimally protected against moisture attack.Name : Deolink VH Description : Avtivator for fillerComposition : Alkoxy-silanes, 50 % in polymer/wax carrier Appearance : White pelletsAnalytical values Dropping point (oC) , Mettler-apparatus DIN ISO 2176 : 105-115Density at 20oC (g/cm3) DIN ISO 787 part 10A : 0.9Dosage : 1-6 %,in relation to silica-fillerSupply Form : 20kg in cardboard boxes with PE-inlinerStorage StabilityIn originally sealed package,in cool and dry places : min.1year Classification and LabellingDeolink VH is labelled as"irritant" (Xi) according to EEC directives.For  more detailed information, please refer to our Material Safety Data Sheet.Behaviour and EffectsDeolink VH forms a chemical bond between the rubber molecule and the silica filler. In Deolink VH the active silane is protected against moisture attack by the polymer-wax matrix. The pellet shape allows fast weighing and safe and easy handling.In contrast to Deolink Vinyl, which can develop methoxyethanol by hydrolysis form the active substance, Deolink VH does not form any methoxyethanol.Application:Deolink VH is used to improve the physical properties of peroxide cured compounds like cable covering, as it acts as a coupling agent between rubber and silica or other filler containing hydroxyl groups.Name : Deolink VinylDescription : Activator for fillerActive substance: Tris(2-methoxyethoxy)vinylsilane  Silane conternt (%):  50Appearance : White pellets Analytical values Lodine value Din 53241 T1 : 45 2.5Dropping point(oC), Mettler-apparatus DIN ISO 2176 : 72 5Density at  20oC (g/cm3) DIN ISO 787 part 10A : 1.0Dosage: 1-6%,in relation to fillerGerman Food Legistlation(BfR recommendation LII): max. 1%,in relation to fillerSupply Form: 20 kg in cardboard boxes with PE-inlinerStorage Stability:In originally sealed package,in cool and dry places : min.1 yearClassification and LabellingDeolink Vinyl is labelled as "harmfull"(Xn) according to EEC directives. For more detailed information, please refer to our Material Safety Data Sheet.Behaviour and EffectsDeolink Vinyl forms a chemical bond between the rubber molecule and the silica filler. The methoxyethanol which is formed owing to the reaction evaporates during the mixing and vulcanisation process. In Deolink Vinyl the active silane is protected against moisture attack by the wax polymer matrix. The pellet shape allows fast weighing and safe and easy handling.ApplicationDeolink Vinyl is used to improve the physical properties of peroxide cured compounds like cable covering, as it acts as a coupling agent between rubber and silica or other filler containing hydroxyl groups. Compared to compounds without silanes the electrical properties are improved by Deolink Vinyl.More Details.
