HH-66™ vinyl cement makes incredibly strong seams on vacuum bags. I have tried nearly every chemical in the Grainger and 3M catalog and nothing works like HH-66. 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.

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. A nearly-instant bond is made on contact with vinyl material. Polyurethane material requires clamping for 24 hours.
