LORD 7545-C

Description

Description

LORD® 7545 adhesive is an equal-mix, two-component urethane adhesive system used to bond FRP, SMC and other plastics with little surface preparation. This adhesive also bonds primed metals and various combinations of dissimilar substrates. LORD 7545 adhesive system is available in a range of working times to accommodate a wide variety of process requirements.

Features and Benefits

Durable – demonstrates high strength and excellent durability for structural applications. Non-Flammable – exceeds U.S. DOT requirements for non-fl ammability and does not require explosion-proof equipment.

Suitable Appearance – off-white color of cured adhesive provides an acceptable appearance when non-painted or visible.

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.

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

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, prime or grit blast the surface, then solvent wash for optimum bond performance.

Mixing – Mix LORD 7545-A resin with the appropriate curative at a 1:1 ratio, by volume. Handheld cartridges will automatically dispense the correct volumeric ratio of each component. Once mixed, the adhesive cures rapidly.
