CH 11

Color: Grey
Type : Primer

Chemitac 11 is a one-coat heat reactive primer for bonding elastomers as NBR, ACM and solid PU with steel, aluminum, aramid, textile fibers and glass by vulcanization process. The textile fibers can be: Cotton, cellulose, polyamide, polyester, and aramid. Chemitac 11 is also used in two coats systems together with an adhesive to bonding NR, SBR, BR, CR, NBR, HNBR, IIR, CIIR, BIIR, CSM, and EPDM. Chemitac 11 is a heavy metal-free product.
