Sikaflex 2c NS EZ Mix is a two-component, premium-grade, polyurethane-based, elastomeric sealant. It is principally a chemical cure in a non-sag consistency. Sold with a color pack.

  • Capable of ± 50 % joint movement.
  • Chemical cure allows the sealant to be placed in joints exceeding 13 mm (1/2 in) in depth for non-moving joint.
  • High elasticity with a tough, durable, flexible consistency.
  • Exceptional cut and tear resistance.
  • Exceptional adhesion to most substrates without priming.
  • Available in 35 standard architectural colours.
  • Colour uniformity assured via Color-pak system.
  • Available in pre-pigmented Limestone Grey (no Color-pak needed) (special order only).
  • Non-sag even in wide joints.
  • ANSI/NSF 61 approval for contact with potable water (special order only).
  • Easy to mix.
  • Paintable with water, oil, and rubber-base paints.
  • Meets ASTM C 920, Type M, Grade NS, Class 25, use T, NT, M, G, A, O.
  • Meets Federal Specification TT-S-00227E, Type II, Class A.
  • Meets Federal Specification TT-S-001543A
  • Meets Federal Specification TT-S-00230C
  • Meets CAN/CGSB 19.24 - M90.
  • USDA approved.
  • Canadian Food Inspection Agency acceptance.
  • Ministry of Transport Québec acceptance.
  • UL Fire Stopping Approved (FF-S-1034, FW-S-1020, HW-S-1018, WW-S-1037)
  • Intended for use in all properly designed working joints with a minimum depth of 6 mm (1/4 in).
  • Ideal for vertical and horizontal applications.
  • Placeable at temperatures as low as 4°C (39°F).
  • Adheres to most substrates commonly found in construction.
  • An effective sealant for use in Exterior Insulation Finish Systems (EIFS).
  • Submerged environments, such as canal and reservoir joints.
  • The ultimate performance of Sikaflex® 2c NS EZ Mix, depends on good joint design and proper application.
  • Some substrates require priming. Please refer to the Sikaflex® Primers Technical Data Sheet or consult with Sika Technical Services.
  • Minimum depth in working joint is 6 mm (1/4 in).
  • Maximum expansion and contraction should not exceed 50% of average joint width.
  • Do not cure in the presence of curing silicones.
  • Avoid contact with alcohol and other solvent cleaners during cure.
  • Allow 3-day cure before subjecting sealant to total water immersion.
  • Avoid exposure to high levels of chlorine. (Maximum level is 5 ppm).
  • Do not apply when moisture vapour transmission exists since this can cause bubbling within the sealant.
  • Avoid over-mixing sealant.
  • Light colour shades tend to yellow over time when exposed to ultraviolet rays.
  • When overcoating, an on-site test is recommended to determine actual compatibility.
