Details

Where to Use 

  • Designed for all types of joints where maximum depth of sealant will not exceed 1/2 in. 
  • Excellent for small joints and fillets, windows, door frames, reglets, flashing, common roofing detail applications, and many construction adhesive applications.
  • Suitable for vertical and horizontal joints; readily placeable at 40°F.
  • Has many applications as an elastic adhesive between materials with dissimilar coefficients of expansion.
  • Submerged conditions, such as canal and reservoir joints. 
 

Advantages 

  • Eliminates time, effort, and equipment for mixing, filling cartridges, pre-heating or thawing, and cleaning of equipment.
  • Fast tack-free and final cure times. n High elasticity - cures to a tough, durable, flexible consistency with exceptional cut and tear-resistance.
  • Stress relaxation.
  • Excellent adhesion - bonds to most construction materials without a primer.
  • Excellent resistance to aging, weathering.
  • Proven in tough climates around the world.
  • Odorless, non-staining.
  • Jet fuel resistant.
  • Certified to the NSF/ANSI Standard 61 for potable water.
  • Urethane-based; suggested by EPA for radon reduction.
  • Paintable with water-, oil- and rubber-based paints.
  • Capable of ±35% joint movement.

Limitations

  • When overcoating with water, oil and rubber based paints, compatibility and adhesion testing is essential.
  • Sealant should be allowed to cure for 7 days prior to overcoating.
  • Avoid exposure to high levels of chlorine. (Maximum continuous level is 5 ppm of chlorine.)
  • Maximum depth of sealant must not exceed 1/2 in.; minimum depth is 1/4 in.
  • Maximum expansion and contraction should not exceed 25% of average joint width.
  • Do not cure in the presence of curing silicone sealants.
  • Avoid contact with alcohol and other solvent cleaners during cure.
  • Do not apply when moisture-vapor-transmission condition exists from the substrate as this can cause bubbling within the sealant.
  • Use opened cartridges and uni-pac sausages the same day.
  • When applying sealant, avoid air-entrapment.
  • Since system is moisture-cured, permit sufficient exposure to air.
  • White color tends to yellow slightly when exposed to ultraviolet rays.
  • Light colors can yellow if exposed to direct gas fired heating element.
  • The ultimate performance of Sikaflex-1a depends on good joint design and proper application with joint surfaces properly prepared.
  • The depth of sealant in horizontal joints subject to traffic is 1/2 in.
  • Do not tool with detergent or soap solutions.
  • Do not use in contact with bituminous/asphaltic materials.
