Description

Description 

LORD® 7542 adhesive is an equal-mix, two-component urethane adhesive system used to bond FRP, SMC and other plastics with little surface preparation. This adhesive will also bond primed metals. LORD 7542 adhesive system is available in a range of working times to accommodate a wide variety of process requirements. 

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.

Temperature Resistant – performs at temperatures from -30 to +250°F (-34 to +121°C). 

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

UL Rated– UL 746C certified.

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 7542-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.

Applying – Apply adhesive using handheld cartridges or automatic meter/mix/dispense equipment.
• Handheld Cartridges
1. Load the cartridge into the applicator gun and remove the end caps.
2. Level the plungers by expelling a small amount of adhesive to ensure both sides are level.
3. Attach mixing tip and expel a mixer’s length of adhesive.
4. Apply adhesive to substrate and mate the parts within the working time of the adhesive. Clamp in position until adhesive reaches handling strength.
