Full definition
A single-component, solvent-based (or water-based) adhesive containing dissolved polychloroprene (neoprene) or SBR rubber that bonds by the contact bonding technique: adhesive is applied to both mating surfaces, allowed to dry until tacky (when a finger test shows no transfer — typically 10-20 min), then the surfaces are pressed together firmly for an instant, strong bond. No clamping time required — the bond is immediate upon contact. Peel strength: 2-5 N/mm. Temperature resistance: 60-80°C (single-component), 100-120°C (two-component with isocyanate hardener). Applications: general rubber-to-rubber bonding, rubber-to-metal/wood/fabric lamination, flooring installation, footwear manufacturing, leather goods, and workshop repairs. The key advantage is speed — no clamping, no cure waiting — but the bond is contact-only, meaning surfaces must be aligned correctly before pressing together (repositioning is very difficult once contact is made). Solvents: toluene, hexane, or acetone blends; water-based versions are available with lower VOC but slower dry time and slightly lower bond strength. Per manufacturer application guides. Brands: Bostik (Evo-Stik), 3M Fastbond, Renia, Stabond, DAP Weldwood.
