  • High-strength polyurethane foam substrate is chemically compatible with all silicones tested to ASTM C1087*
  • Semi-rigid foam acts as a spacer for structural glazing systems
  • Exhibit high initial adhesion, speeding on-site fabrication
  • Open cell urethane foam allows for optimum silicone curing
  • Certified no color change or staining after independent testing*
  • Resist temperature variations, fungi, oxidation and discoloring with age
  • Adhere to bare metal, glass, and painted surfaces
  • Reduce heat transfer, improves wall performance, and can support LEED points

*List of manufacturers and silicones tested available upon request. Refer to silicone manufacturer for compatibility information. Each project should be individually lab tested to confirm compatibility between Pres-On SG6400, structural silicone, and all other adjacent materials.
