LORD 7650 Urethane Adhesive

Description

LORD® 7650 is a single-component, moisture-cure urethane adhesive engineered to provide the initial tack of a contact adhesive with the permanent crosslink strength of a urethane bond. This versatile, high-performance adhesive is ideal for applications in manufacturing, construction, and transportation where durable, long-lasting bonds are required.

It adheres to a broad range of substrates including open-cell polyethylene foam, styrofoam, urethane foam, plastics, fabrics, rubber, and prepared metals. Typical uses include gaskets, tank linings, automotive interiors, carpeting, construction panels, and flooringDatasheet—LORD7650_DS….

Key Features & Benefits

• High Initial Tack – Grabs surfaces quickly, reducing clamping needs.
