Application Guidelines

Application Temperature:
Above 0°F (-18°C)
Service Temperature Range:
-75°F to 300°F (-59°C to 149°C)
Method of Application:
Cartridge/caulking gun
Tooling Time:
For a 1/4" bead, approximately 10-15 minutes, depending on temperature and humidity.
Application Directions:
1. Surfaces must be clean and free of any material that may prevent adequate adhesion. 2. Remove nozzle, cut tip of the nub and puncture inner foil seal. 3. Screw nozzle onto cartridge and cut tip on slant for 1/4" to 3/8" bead and place in cartridge gun. 4. Force sealant into clean joint. Always apply sealant in bead form. No tooling is required. It is the sole responsibility of the user to thoroughly test any proposed use with all substrates to determine project suitability.
Cleanup:
Clean uncured material with acetone or isopropyl alcohol. After curing, excess sealant must be cut or scraped away. Follow solvent vendor's precautions when using solvents.
Substrate Compatibility:
Excellent adhesion to Kynar™ coated materials. For use on polycarbonate, check with polycarbonate supplier on compatibility. For questions, please call our Help Line at 1-800-347-4583.

Limitations:
Not designed for continuous submersion or use below the waterline. Air, sealant and surface temperature should be above 0°F. Copper should be coated to eliminate oxidation before sealing. Sealant is intended for exterior use. If used indoors, sealant may need to be painted. Painting may occur one hour after application with a water-based (latex-based) paint. For other paint types, a compatibility test is recommended. It is highly recommended to use backing material for all joints. For best results, store in a dry location at or below 75°F.
