TAC 250 for Industrial Rubber Bonding
SpecBond 32 is TAC 250, a two-component polychloroprene contact adhesive used with SPEC 33 (IRODUR E 462) curing agent. It provides secure adhesion, heat resistance and practical open time for industrial rubber bonding applications.
Applied cold, SpecBond 32 supports workshop fabrication, plant installations and field maintenance across mining, quarrying, manufacturing, materials handling and other industrial operations.
Oreflow stocks SpecBond 32 in 20 L drums together with SPEC 33 curing agent at our Perth warehouse for local and Australia-wide supply.

Surface Preparation and Bonding
Clean, dry and correctly prepared surfaces are essential to achieving optimum bond strength.
1. Prepare the Substrates
Remove rust, oil, dust and other contamination. Sandblast metal and buff rubber where required.
2. Clean and Prime
Clean prepared metal with TAC 101 Contact Cleaner and apply Chemlok 205 Metal Primer. Clean prepared rubber with a suitable quick-drying petroleum-based solvent.
3. Mix and Coat
Mix approximately 4–7% SPEC 33 curing agent by weight. Use the mixed adhesive within two to three hours and apply two coats, allowing approximately one hour between coats.
4. Assemble the Bond
Allow the second coat to become non-tacky, join the surfaces before the open time ends and apply firm, even pressure.
SpecBond 32 contains flammable solvents and requires appropriate PPE, ventilation, storage and handling controls. Refer to the current Safety Data Sheet for complete safety information.
