LORD® 7556-A/7556-B Urethane Adhesive Where To Buy


Product Information

LORD® 7556-A/7556-B adhesive is an equal-mix, two-component clear urethane adhesive system used to bond Lexan®, ABS, polycarbonate and other plastics. This adhesive will also bond primed metals.

Lexan is a trademark of SABIC Innocative Plastics.

Shelf Life

Shelf life is six months 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

Non-Flammable – does not require expensive explosion-proof equipment.

Environmentally Recommended – does not contain ozone depleting chemicals.

Environmentally Resistant – resists weathering, humidity and salt spray; UV resistant.

Chemically Resistant – solvent resistant when cured. Painting and most cleaning processes do not affect bond strength.

Non-Sag – remains in position when applied on vertical or overhead surfaces, allowing for greater process flexibility.
