Best Practices for Bostik LoVoc Seal White
-
Surface Preparation
Substrates should be free of all loose contamination, grease, oils, etc. Use isopropyl alcohol or other approved solvent for substrate degreasing. Alcohols must be allowed to completely flash off from the substrate before LoVOC Seal™ application. Temperatures of substrates and LoVOC Seal™ must be above 40°F (4°C). Recommended substrate/ product application temperatures are between 55°F and 100°F (13°C and 38°C).
-
Application
Cut nozzle to the desired bead size and puncture the inner foil seal. Place sausage or cartridge into either a manual or pneumatic sausage/cartridge dispenser caulking gun. Apply appropriate pressure to install LoVOC Seal™ so as to insure full contact (surface wetting) to promote sealing and adhesion performance. Tool and finish applied LoVOC Seal™ immediately to promote the best mechanical adhesion and cured appearance.
-
Clean-Up
Uncured LoVOC Seal™ can be easily removed from hands, tools and substrates by using Bostik® Hand & Tool Towels. Removing cured LoVOC Seal™ from substrates will require mechanical methods—scrapers, putty knives.
