Catalysts & Vulcanization Accelerators

Product	% Active	Description / Attributes	TDS	Sample
Single Accelerators
Deovulc OTOS-80	80	Enables the dust- and spot-free incorporation of this accelerator. Deovulc OTOS improves reversion stability & mechanical / dynamic properties
Deovulc TP 4-75	75	Zincdialkyldithiophosphate, absorbed on a silica carrier. Deovulc TP 4 is used as an accelerator for nitrosamine-free vulcani zates based on EPDM or diene rubber.
Deovulc ATP-70	70	Amine activated dithiophosphate Deovulc ATP is designed for the rapid cure of EPDM and diene rubber
Accelerator Blends & Preparations
Deovulc EG 3	- - -	Highly active blend of accelerators suitable for general applications requiring a medium cure rate and an average compression set.
Deovulc EG 28	- - -	Highly active accelerators (ETU-free) with additional sulphur donor. Rapid full cure and a high degree of cross-linking combined with low compression set values.
Deovulc BG 187 (nitrosamine free)	- - -	Combination of Thiazole-, Dithiophosphateand basic accelerators available as non-dusting powder or granules

Activators & Sulfur Preparations

Activators
Deovulc ZO	100	Zinc-2-ethylhexanoate and acts as an activator for the vulcanization of natural rubber.
Deovulc ZO-DL	67	67% dry liquid of Deovulc ZO.
Deovulc OH	96	Particularly fine calcium hydroxide, which acts as an acid scavenger and cross-linking activator in fluoroelastomer based compounds.
Sulfur Preparations
Deosulf L 95	99.5	Dust free and enable a uniform dispersion. No agglomerations occur, local overcure is avoided and consequently vulcanizates with excellent ageing properties are obtained.
Deosulf U 60	53	Enables the perfect incorporation of insoluble sulfur into rubber. The safety against scorch is improved and the danger of sulfur bloom is reduced
