Application

Surface Preparation –Surfaces should be free of grease, dirt and other impurities. 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.

When bonding cured rubber, allow Lord 7701 adhesion enhancer/surface modifier to flash off before applying LORD 7650 adhesive.

Applying –Apply LORD 7650 adhesive by roll coat, spray, brush or fl ow coat methods. Unlike contact adhesive, applying the adhesive to one side of the substrate is suffi cient.

Curing – Handling strength is achieved after a 15-30 minute solvent fl ash. Complete cure will take 1-5 days depending on substrate being bonded and relative humidity.
