ACA 20-527 bonds asphalt sound dampening parts to steel. ACA 20-527 will ensure that the die cut asphalt parts will remain well bonded and in registry on steel stamped parts even though the parts may be exposed to high temperatures or low temperatures during transportation and assembly. The pH of the adhesive has been adjusted so as to avoid flash rusting of the metal substrate. Heat age testing indicates that the asphalt does not migrate into the adhesive, a common cause of adhesive failurre.
- Coating Method
Application of the adhesive may be by brush or roller on the specific areas required followed by drying with forced air at elevated temperatures.
- Clean Up
Wash the equipment with water to remove the wet adhesive. Dry adhesive may require a toluene wash. Toluene is an inflammable, volatile solvent and should be used in conformance with OSHA guidelines.
