PPG PR 1422 A 2 PART A Technicial Specifications Surface preparation Surfaces should be cleaned with solvent just before applying mastic to primed surfaces. Contaminants such as dirt, grease and/or processing lubricants must be removed prior to sealant application. Appropriate solvents and a new lint-free cloth should be followed by a gradual cleaning procedure (recycled solvents or tissue paper should not be used). Always pour solvent on the cloth to prevent contamination of the solvent source. Wash a small area at a time. It is important to dry the surface with a second clean cloth before the solvent evaporates, to prevent re-deposition of contaminants on the substrate. The substrate composition can vary greatly. This can affect the adhesion of the sealant. It is recommended to determine the adhesion properties to a given surface before applying to production parts or assemblies. For a more comprehensive discussion of proper surface preparation, please refer to the SAE Aerospace Information Report AIR 4069. This document is available through SAE, 400 Commonwealth Avenue, Warrendale, PA 15096-0001. Mixing instructions The PR-1422 Class A is supplied as a two-piece kit.
