Description
LORD® 7550 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.
Features and Benefits:
- Non-Flammable – does not require explosion-proof equipment.
- Environmentally Friendly – does not contain ozone depleting chemicals.
- Environmentally Resistant – resists sunlight, weathering, humidity and salt spray.
- Chemically Resistant – solvent resistant when cured. Painting and most cleaning processes do not affect bond strength.
- Self-Leveling – flows into hard-to-reach spaces; excellent for bonding parts with tight tolerances
