LORD® 7650 Urethane Adhesive Where To Buy


Product Information

LORD® 7650 adhesive is a single-component, moisture-cure urethane adhesive designed to initially adhere similar to a contact adhesive, however permanently cross-link once cure develops.

LORD 7650 adhesive adheres to open cell polyethylene foam, styrofoam, urethane foam, plastic, fabric, rubber and prepared metal. Typical applications include gaskets, tank linings, automobile interiors, carpeting, construction panels and flooring.

Shelf Life

Shelf life is six months from date of shipment when stored in a clean, dry environment at 70-80°F (21-27°C) in original, unopened container.

After opening, protect adhesive from excessive exposure to moisture by installing desiccant cartridges and/or using dry nitrogen as an inert cover.

Features and Benefits

Easy to Use – provides high initial tack and green strength.

Durable – provides good impact resistance.

Versatile – bonds a wide variety of substrates.

Environmentally Resistant – provides good resistance to water and chemicals.

Convenient – requires no mixing; provides working time of 15-30 minutes; requires no ovens or other heat sources for curing.
