DOWSIL™ Instantglaze Window Assembly Sealant

Designed for use as a backbedding sealant in the assembly of windows and doors. It is used with high-speed XY glazing equipment to improve manufacturing productivity and window performance. It can be used on most common window materials (wood, PVC, Aluminum, Fiberglass) for standard and impact-resistant glazing. It is also compatible with most common insulating glass sealants.

Benefits:

  • Improved air and water performance
  • Reduce manufacturing time and cost with automated processing
  • Allow use of standard hot melt dispensing equipment and automated X-Y glazing tables for faster production
  • Save substantial labor time compared with manual tape glazing
  • Outperform organic hot melt sealants such as polyurethanes and butyls
  • Improve quality, reduce costs and reduce volatile organic compounds (VOCs)
  • Minimize waste and cleanup requirements
