SKN-EL rubber is a block copolymer of carboxylated nitrile-butadiene oligomer and epoxidated one. It is produced as a composition with epoxy components to be compatible with epoxide resins and render the latter more elastic and longer pot living. The resulted epoxies are less fragile, more resistant to cracking and more durable that considerably widens their applications.
Rubber compound cures at 15-30oC (RTV), is safe to handle as it is solvent-free.
Rubber has good bond strength to concrete, reinforced concrete, wood and metal, is resistant to some corrosive media, oils and petrol, serviceable up to 100oC.
