Deovulc ATP-70 by DOG Chemie is a preparation of zincdialkyldithiophosphate and amine,70 % adsorbed on silica. Used as vulcanization accelerator for rapid cure of EPDM and diene rubber. Deovulc ATP-70 provides low compression set as well as very good heat aging results. Deovulc BG 187 by DOG Chemie is a synergistic combination of thiazole-, dithiophosphate- and basic accelerators. Deovulc® ZO DL by DOG Chemie is Zinc-2-ethylhexanoate, absorbed on silica filler. Acts as a vulcanizing activator. It improves stability of the system by offering higher cross-link concentration. Also provides reversion, compression set and dynamic properties. Mainly recommended for natural rubber and also for diene rubber. Deovulc® ZO DL can be added with filler and partly or fully replace stearic acid. The dosage rate is 2-5 phr. Deovulc® OH by DOG Chemie is calcium hydroxide. Acts as an acid scavenger and cross-linking activator. It provides high activation and spotless dispersion. Used in fluoroelastomer-based compounds. Recommended to be used at dosage of 5-8 phr. Deovulc® OH at 6phr combined with 3phr MgO are added to the compound together with the filler. Deovulc® CTP-PVI by DOG Chemie is N-(cyclohexylthio)phthalimide. Acts as a vulcanizing inhibitor. It retards scorching thereby prolonging flow time and storage ability. Slightly scorched compounds can also be brought back to processibility. It is added together with the accelerators in the last mixing step, usually in combination with sulphenamides, but thiurames and guanidines can also be used. Deovulc® CTP-PVI is recommended for NR, SBR, BR, NBR, IIR and EPDM rubbers. The dosage rate is 0.1-1.0 phr. Deovulc BG 187 Granulat by DOG Chemie acts as a vulcanizing accelerator. It is a combination of thiazole-, dithiophosphate- and basic accelerators. It does not form toxic nitrosamines.<br>
<ul style="padding-left: 40px;"><li>Recommended for nitrosamine-free, non-blooming and non-staining vulcanized articles, mainly EPDM.</li>
<li>By addition of ZBEC or TBzTD or CBS, cure times can be shortened.</li>
<li>The recommended dosage rates of Deovulc BG 187 Granulat
are 5-7 phr for black compounds, 7-9 phr for light-colored compounds, 0.8-2.0 phr (preferably 1.2-1.5 phr) for sulfur.</li></ul> Zinc-2-ethylhexanoate, absorbed on silica filler. Acts as a vulcanizing activator. It improves stability of the system by offering higher cross-link concentration. Also provides reversion, compression set and dynamic properties. Mainly recommended for natural rubber and also for diene rubber. Can be added with filler and partly or fully replace stearic acid. The dosage rate is 1-4 phr. Deovulc ZBEC-70 by DOG Chemie is a zinc-bis-dibenzyldithiocarbamate. Used in EPDM and diene-rubber as a primary or secondary accelerator. Deovulc TBzTD-80 by DOG Chemie is a tetrabenzylthiuramdisulfide. Used as accelerator. Offers heat resistance and ageing properties. Deovulc ZBEC-80 by DOG Chemie is zinc-bis-dibenzyldithiocarbamate. Used in EPDM and diene-rubber as a primary or secondary accelerator.
