Rubber Industry and Casting Resins

Resins manufactured from alkylresorcinols are used as the resorcinol component in powder bonding systems to increase the adhesiveness of cort to rubber.

Using resins ensures excellent bonding and durability. Resins should be hardened using in situ technologies with formaldehyde, hexamethoxymethylmelamine or hexamethylenetetramine. Alkylresorcinol-based resins harden faster than resorcinol resins.

SF-281

SF-281 resin is obtained by polycondensation of shale phenols and alkylphenols with formalin in the presence of a catalyst. An additive is added to reduce dusting and caking during storage.

Applications

In rubber mixtures to improve the adhesiveness of rubber to cort, and to increase the wear resistance of car tires and rubber products;
Manufacture of casting moulds;
Manufacture of refractory materials from dolomite (binder);
Manufacture of flying targets for shooting sports (binder).
