R-196 is a our go to product for bonding hypalon, neoprene, and many other materials.
Rainbow R-196 is a high performance , fast tacking, solvent-neoprene based adhesive that exhibits high initial green strength and good to excellent heat resistance with superior cohesive strength upon dead load testing.
Available shelf life will vary.
Features
Especially suited for rapid lamination and as a high performance adhesive, it is used for bonding leather, SBR, neoprene rubber stocks, metals, foils, foams, synthetic fabrics, synthetic rubbers, synthetic rubber foams, urethane foam, most plastics, and hard-to-adhere synthetic fabrics (such as Hypalon & Kevlar).
Contact bonding of foam to rubber and to metal, contact bonding of automotive trunk and door gaskets, attaching decorative plastic laminates to wood used to bond molded neoprene and SBR rubber stocks to themselves.

SUGGESTED METHODS OF APPLICATION & BONDING
Brush, knife or roller. Clean the substrates with damp cloth of Toluol.
If the substrate is a coated cured fabric, then it must be abraded first. After the substrate are cleaned and allowed to dry, apply the first coat of adhesive on both surfaces. Allow 20-30 minutes for the material to dry and apply a second coat.
This product may be either solvent reactivated or it may be used as a modified contact cement. When solvent reactivating, after final coat is dry, wipe adhesive with a cloth dampened with Toluol. When the cement becomes aggressively tacky, bond the two surfaces together and press with as much pressure as is possible / practical for the application. When using as a modified contact cement, allow the final coat to dry for 3-5 minutes and then bond the two surfaces together and press with as much pressure as is possible / practical for the application.
To heat reactivate, apply temperatures in the range of 160 - 200 deg.F. (72 - 93 deg.C.) by means of an infrared lamp or oven. Rainbow R-196C can be used as a one-part heat curable adhesive. After the seams are joined together allow to set overnight prior to cure. The recommended cure cycle for this adhesive is 275 deg. F. for 1 hour. Allow to cool prior to testing. Bonded surfaces should be allowed 72 hours of curing time prior to subjecting them to high stress, pressure or heat.
STORING AND HANDLING
For optimum shelf life of this product, store at temperatures
60 - 80 deg.F. (16 - 27 deg.C.). Lower temperatures will cause increased viscosity of a temporary nature; whereas higher temperature can cause a permanent effect on viscosity.
