CH 261

Color: Black
Type: Adhesive

Chemitac 261 is a thermoreactive adhesive used with primers Chemitac 11, for bonding elastomers as NR, SBR, BR, CR, NBR, HNBR, IIR, CIIR, BIIR, CSM and EPDM with steel, aluminum, aramid, textile fibers and glass by vulcanization process. In bonding applications for textile fibers with pretreatment RFL (Resorcinol, Formaldehyde and Latex), Chemitac 261 is applied without primer. The textile fibers can be: Cotton, cellulose, polyamide, polyester and aramid. Chemitac 261 is a heavy metals free product.
