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 Recommended –does not contain ozone depleting chemicals.
Environmentally Resistant – rresists 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.
Application
Surface Preparation –Surfaces should be free of grease, dirt and other contaminants. For plastics, clean the surface with a dry rag wipe or a rag dampened with solvent. For metals, grit blast and solvent wash the surface, then prime for optimum bond performance.
Mixing –Mix resin with the curative at a 1:1 ratio, by volume. Handheld cartridges will automatically dispense the correct volumetric ratio of each component
Applying –Apply adhesive using handheld cartridges. Assemble parts within working time of the adhesive.
