HH-66 is a superior quality, fast drying (2-5 minutes), waterproof, solvent-synthetic resin adhesive. It is used extensively for bonding vinyl coated and vinyl laminated fabrics like Shelter-Rite and Boat Top to themselves or to various materials. Also used to bond urethanes, vinyl foams and films, leather, and metals. Outstanding for sealing or waterproofing stitched seams.
HH-66 dries hard and very strong, yet remains flexible. It is not affected by weather and temperature extremes, and is highly resistant to oil, fuel, grease, and many chemicals.
Application is by brush, roller, or squeeze bottle. Dried films may be reactivated to a tacky state by high heat or solvent. HH-66 can be stored one year or longer, under normal conditions.
HH-66 is used widely in the manufacture and repair of vinyl tarpaulins, truck and pool covers, tents, awnings, liners, domes, inflatables, flexible signs, mats, tension structures, furniture, and sporting goods. Other vinyl applications have been with protective clothing, roofing and flashing, automotive materials, oil booms, footwear, flexible hose, industrial curtains, dock seals, and vinyl repair kits.
