Tool sealant - Ideal for sealing hairline cracks in composite and metallic tooling

Features and Benefits
• High temperature capable elastomeric coating made from high performance materials, used to seal against vacuum loss due to hairline cracks in composite and metallic tooling.
• Allows composite tooling to be quickly repaired and returned to service.
• Light cream color ensures adequate, highly-visible coating coverage on normally black tool surfaces.
• Supplied in thin milled sheet form with instructions on mixing with solvent to produce the coating consistency required.
• For best results, the coating should be applied to the reverse side of the leaking tool surface while vacuum is being pulled over the face of the tool, thereby allowing the sealant to  penetrate the leaking areas.
• The solution will air-dry and achieve maximum adhesion after use in an oven or autoclave.
