HH-66™ vinyl cement makes strong seams on vacuum bags. Each can has a built-in brush attached to the lid for easy application. This vinyl cement is clear, fast drying, waterproof, and remains flexible. HH-66 has a nearly instant bonding action on most vinyl surfaces when prepared and applied appropriately.

This product is designed to work with vinyl membranes and sheeting. However, we have found that it will also bond our polyurethane sheeting if the material is cleaned with acetone or xylene and lightly abraded with a synthetic wool pad. Polyurethane material requires clamping for 24 hours for a successful bond.

HH-66 dries quickly with a very strong, yet flexible bond. It is not affected by weather and temperature extremes, and is highly resistant to oil, fuel, grease, and many other chemicals. The 1/4-pint (4 oz.) is enough to build one large (4 x 8) vinyl vacuum bag or several smaller bags.

About Our Pricing: You may notice that our price is higher than many other suppliers. Search around online and you can save a few bucks. Our pricing is higher because my wife and I had to take a very expensive training class just to be able to ship this product. We don't sell much of this adhesive so it's going to take time for us to pay off that expense. We are currently selling HH-66 at our net cost.

Update: The manufacturer has been raising prices by significant amounts - there have even been multiple large increases in a single year! I recently tested a few other vinyl cement products and I believe they all work about the same. So if you can find a less expensive option, it should work fine on our vinyl and polyurethane.
