Apply a thin layer by spraying, using a squeegee or a clean lint free cloth. Allow to stand at room temperature for 2 hours then repeat process if required. Lightly sand if required after cure.
Cure:
Room temperature: 12-16 hours, at 150°F (66°C): 2 hours
Post cure:
Post cure at the intended use temperature for one hour to a maximum temperature of 360°F (182°C) and apply mold release.
Application instructions for restoring tool face or vacuum integrity to composite or metal molds:
• Prepare tool surface to be coated by sandblasting or manually abrading with heavy grit sandpaper.
• Solvent wipe to remove all contaminates and completely dry.
• Vacuum bag the complete face side of the tool and draw partial vacuum. 5 inHg and 10 inHg
(0.17 and 0.34 bar).
• Apply a thin layer to the back side of the tool by spraying, squeegee or brush.
• Allow the cure at room temperature overnight or accelerate tack by curing at 150°F (66°C) for 2 hours.
• Post cure tool to 360°F (182°C) for 2 hours.
• Check tool for vacuum integrity. Apply additional coats if required.
• Light sanding may be required when Print-Seal is applied to the tool face for resurfacing.
• Please
