Sikaflex®-709 Insulation Sealant & Adhesive

Universal Flashing Sealant /  Adhesive

4.6 (352)

Sikaflex®-709 Insulation Sealant & Adhesive is a one component, gun grade, flashing sealant designed to adhere to a wide range of air, vapor and weather barrier surfaces. Sikaflex®-709 Insulation Sealant & Adhesive provides an excellent seal at transitions between dissimilar materials. Sikaflex®-709 Insulation Sealant & Adhesive can be used for weather sealing where low movement is expected.

  • Excellent resistance against weathering and moisture
  • UV stable for exterior applications
  • Noncorrosive
  • Can be painted over with water, oil, and rubber-based paints (preliminary Adhesion and Compatibility tests recommended)
  • High durability
  • Excellent unprimed adhesion to a wide range of building materials including many weather membranes such as peel and stick, spun-bounded thermoplastic and liquid applied membranes.
  • Compatible with asphaltic and bituminous materials
  • Forms an elastic bond with great durability
  • Excellent unprimed adhesion to a wide range of "hard to bond" surfaces such as polyethylene surfaces, polypropylene surfaces, common polyolefins, PVC, steel, metals, aluminum, glass, etc.
  • Compatible with natural stones and other porous surfaces susceptible to staining, shadowing or silicone fluid migration.

Application steps

SUBSTRATE PREPARATION

Mechanically clean all surfaces. Interior joint surfaces walls must be sound, clean, dust-free, dry, frost-free, and free of oil, grease and any other contaminants.

Porous Substrates – Clean by mechanical methods to expose a sound surface free of contamination and laitance.

Nonporous Substrates – Lightly abrade smooth surfaces and remove loose dust and debris.  Wipe surfaces using a clean white cloth dampened with either Isopropyl Alcohol, Acetone, MEK or Xylene.  Follow solvent wipe with a clean, dry rag wipe.  Ensure cleaning agent has completely evaporated away prior to Sikaflex®-709 Insulation Sealant & Adhesive installation.

CLEANING OF TOOLS

Uncured material can be removed from surfaces with an approved agent (e.g. Isopropyl Alcohol, Acetone, MEK or Xylene). Cured material can only be removed mechanically. For spillage - collect, absorb, and dispose of in accordance with current, applicable local, state, and federal regulations.
