PPR-1005 is a thin liquid, allowing for application by brush, fill and drain, or dipping. The compound cures at room temperature by the evaporation of solvent to form a smooth, tough, flexible, transparent film.
- Immediately before applying PR-1005 to metallic, chemically treated, or painted substrates, the surfaces should be cleaned with solvents to remove contamination such as dirt, grease, and/or processing lubricants.
- A progressive cleaning procedure should be employed using the appropriate solvents and new lint-free cloth (reclaimed solvents or tissue paper should not be used). Always pour the solvent on to the cloth to avoid contaminating the solvent supply. Wash one small area at a time. It is important that the surface is dried with second clean cloth prior to the solvent evaporating to prevent the redeposition of contaminants on to the substrate.
- Substrate composition can vary greatly. This can affect sealant adhesion. It is recommended that adhesion characteristics to a specific substrate be determined prior to application on production parts or assemblies. For information on specific substrate treatment please refer to the Surface Treatment leaflet which is available on request.
