Description

SKDSN-S rubber is a low-molecular-weight product of the polymerization of butadiene in solution under the influence of an anionic catalyst.
Rubber at ordinary temperatures is a transparent, thickly viscous mass from colorless to light yellow. Microstructure: 35-50% 1,2-vinyl, 30-40% 1,4-trans, 15-25 % 1,4-cis.

Areas of use

Coagent in EPDM rubber compounds, solid electrical sealants, defoamers for paint and varnish coatings, reactive plasticizer for UV-curing flexographic printing plates,
automotive sealants and adhesives cured with sulfur or hydrogen peroxide, coagent in rubbers and elastomers cured with sulfur or hydrogen peroxide.

Packaging And Transportation

SKDSN-S rubber is packaged in steel barrels with a capacity of 100 to 275 dm³, IBC. The product is transported by any type of transport.

Warranty period

The guaranteed shelf life of rubber is one year from the date of manufacture.
