Accelerators

Western Reserve Chemical supplies the following chemicals and additives throughout the North American markets from our three warehouses located across the United States.

Westco™ BZ

(ZDBC) Zinc Dibutyl Dithiocarbamate

An accelerator for natural and synthetic rubber and latex. Provides fast cures at low temperatures; faster cures than EZ(ZDEC or MZ(ZDMC).

Westco™ CBS

(n-cyclohexyl -2- benzothiazole sulfenamide)

Westco™ CBS is a delayed action accelerator suitable for natural rubber and synthetic rubber; produces vulcanizates with high modulus and high tensile strength.

Westco™ CBS Soft Granules

(n-cyclohexyl -2- benzothiazole sulfenamide)

Westco™ CBS is a delayed action accelerator suitable for natural rubber and synthetic rubber; produces vulcanizates with high modulus and high tensile strength.

Westco™ CDMC

Copper Dimethyldithiocarbamate C6H12N2S4 Zn

Westco™ DCBS

(N,N-Dicyclohexyl -2- benzothiazolesulfenamide)

Westco™ DCBS is a slow curing, delayed action, accelerator especially useful in curing thick rubber parts.

Westco™ DETU

(Diethylthiourea)

Westco™ DETU is recommended mainly for latex, where it is used as a primary accelerator. It is active even at low temperatures. Westco™ DETU can be used without zinc oxide for transportation articles.

Westco™ DPG

(Diphenyl Guanidine)

Westco™ DPG can be used as a secondary accelerator with thiazoles and sulfenamides in NR and SBR compounds. Exhibits better storage stability compared to thiuram and dithiocarbamates but is not as active. Can be used in latex as secondary gelli

Westco™ DOTG

Seldom used alone, commonly with thiazoles, thiurams, dithiocarbamates and sulfenamides to promote its activity. Slightly more active than DPG. Unsuitable for food-related products or medical products.

Westco™ DPTT

Westco™ DPTT is used as the primary or secondary accelerator in natural and synthetic elastomers and as a sulfur donor in low sulfur or sulfurless cures. Westco™ DPTT is non-staining and is suitable for use in light colored vulcanizates.

Westco™ DTDM

(4,4'dithiodimorpholine)

Sulfur donor vulcanizing agent for low sulfur or non-sulfur cure system; provides good heat aging resistance in NR and SR when used with sulfenamide accelerators. Crystal form is free flowing and non-dusting.

Westco™ EZ

(ZDEC - ZINC DIETHYLDITHIOCARBAMATE)

Westco ETU

(Ethylene Thiourea)

Westco ETU is an ultra accelerator for polychloroprene rubber. It is also used in latex as a primary accelerator. It is active even at low temperatures. Westco ETU can be used without zinc oxide for transportation articles. It is an antioxidant in ad

Westco™ ETU 80

(80% ETU in an Elastomeric Binder)

Westco™ MBT

(Mercaptobenzothiazole)

Westco™ MBT is a primary accelerator for natural rubber and synthetic rubbers. Excellent low temperature curing properties. May be used in non staining and non black applications.

Westco™ MBDS

(4-Morpholinyl-2-benzothiazole disulfide)

Westco™ MBTS

(Benzothiazole disulfide (2.2'-Dithio-dibenzothiazole))

Westco™ MBTS is a general purpose accelerator for sulfur cures. It is very active above 142°C (287°F). Unlike thiuram disulfides, Westco™ MBTS does not split off active sulfur during vulcanization. For use in natural and synthetic rubber

Westco NaMBT 50

2-Mercaptobenzothiazole solution, sodium salt C7H5NS2Na

Westco NaMBT 50 is a 50% solution of the sodium salt of Mercaptobenzothiazole.

Westco™ MZ

(ZDMC - ZINC DIMETHYLDITHIOCARBAMATE)

Westco™ MZ is an ultra accelerator for NR and SR rubber and latexes and it active over a wide temperature range.

Westco™ OBTS

2-(4-Morpholinothio)-benzothizole

Westco™ TBBS

(N- tert-butyl-benzothiazole sulfonamide)

A delayed action accelerator for use in natural rubber and synthetic rubbers such as SBR, BR, NBR and EPDM. Lower scorch than CBS and can be more safely processed. But slightly faster scorch than OBTS. High modulus and excellent physical propertie

Westco™ TBzTD

(Tetrabenzylthiuram disulfide)

Fast curing primary or secondary accelerator in NR, SBR, NBR. Low to nil nitrosamine; not carcinogenic. Longer scorch times.

Westco™ TETD

Tetraethlythiuram disulfide

Westco™ TETD is an accelerator suitable for most sulfur-cured elastomers. It acts as both an accelerator and a vulcanizing agent. Its low melting point provides excellent dispersion in soft compounds. It is used as a stabilizer in sulfur mod

Westco™ TMTD

Tetramethylthiuram Disulfide

Westco™ TMTD is the most widely used among ultra-accelerators in natural and synthetic rubber; acts as a retarder for CR; an effective accelerator for low temperature cures. Rubber curing accelerator with super anti-scorching and short curing t

Westco™ TIBTD

Tetraisobutylthiuram disulfide

CAS Number : 3064-73-1 Molecular weight :408.756 Applications and Uses • Fast curing primary or secondary accelerator in NR, SBR, NBR rubber and in Chloroprene • As replacement for TMTD and TETD when nitrosamines are of concern

Westco™ TMTM

TETRAMETHYLTHIURAM MONOSULFIDE

Westco™ TMTM is used as a secondary accelerator with sulfenamides, thiazoles and guanidines; good processing safety compared with other thiurams.

Westco™ ZBEC

Zinc dibenzyldithiocarbamate

Primary or secondary accelerator for NR, IIR, SBR, EPDM. Scorch resistance. Low to nil nitrosamines. Primary or secondary accelerator for natural and synthetic lattices. Excellent accelerator in gel and non-gel latex systems.

Westco™ ZMBT

Zinc 2- Mercaptobenzothiazole

Primary accelerator for NR, SR and their latices; used as a secondary accelerator in sulfur cured latex.
