Description

Low molecular weight cis-butadiene rubber SKDN-N is a liquid product of the polymerization of butadiene under the influence of a catalytic system based on nickel salts and organoaluminum compounds.

Areas of use

Adhesive and sealing compositions, polymer printing forms, inks for offset printing, plasticizer for rubber compounds, binders for recycled rubber compounds, electrical insulating and sealing compounds, release agents for polyurethane foam, modifier of resin systems, modifier of vegetable oils, synthesis of binder for anodic coatings by immersion , synthesis of chlorinated rubber, synthesis of binder for oxidatively dried varnishes, binder for oxidatively dried alkyd resins, binder for pulverized and dry quartz sand, binder for soil stabilization, impregnation of mineral substrates, impregnation of cylinder head gaskets. SKDN-N rubber is also a raw material for the production of electrophoresis materials.

Packaging and transportation

SKDN-N rubber is packed hermetically in steel barrels with a capacity of 100, 200 or 275 dm³, or IBC. The product can be transported by any type of transport.

Warranty period

The guaranteed shelf life of SKDN-N rubber for grade 1 is three years, for grade 2 - one year from the date of manufacture.
