Sikaflex®-2C NS TG+

TRAFFIC-GRADE ADDITIVE FOR SIKAFLEX®- 2C NS EZ MIX+

Sikaflex®-2C NS TG+ is a premium-grade, polyurethane-based, additive for use in Sikaflex®-2C NS EZ Mix + sealant. It is principally an additive that helps cure the sealant with a higher Shore A hardness for use in Traffic Grade applications in a non-sag consistency.    When mixed with Sikaflex®-2C EZ MIX +, it is available in 35 standard colors (> 320 special colors) with a convenient Colorpak. Also available as a pre-pigmented product in Limestone Gray. Meets ASTM C 920, Type M, Grade NS, use T, NT, O, M, G, A, and Federal Specification TT-S-00227E.

When used with Sikaflex®-2C NS EZ Mix + is
  • Capable of ± 35 % joint movement.
  • Chemical cure allows the sealant to be placed in joints exceeding 1/2 inch (25.4 mm) in depth.
  • Tough, durable, flexible consistency.
  • Exceptional cut and tear resistance Exceptional adhesion to most substrates without priming.
  • Color uniformity assured via Color-pak system or pre-pigmented Limestone.
  • No Color-pak needed in pre-pigmented Limestone.
  • Jet fuel resistant.

Application steps

SUBSTRATE PREPARATION

All joint-wall surfaces must be clean, sound, and frost free. Joint walls must be free of oils, grease, curing compound residues, and any other foreign matter that might prevent bond. Ideally, this should be accomplished by mechanical means. A roughened surface will also enhance bond. Bond breaker tape or backer rod must be used in bottom of joint to prevent bond.

  

Priming

Priming is typically not necessary. Most substrates only require priming if sealant will be subjected to water immersion after cure. Testing should be done, however, on questionable substrates, to determine if priming is needed. Consult Technical Service or Sikaflex® Primer Technical Data Sheet for additional information on priming.

MIXING

Sikaflex®-2C NS TG+ must be used with Sikaflex®-2C NS EZ Mix +.

  • Pour entire contents of Sikaflex®-2C NS TG+ and Component ‘B’ into pail of Component ‘A’ of the Sikaflex®-2C NS EZ Mix +. For tint base: add entire contents of Color-pak into pail and mix with a low-speed drill (400–600 rpm) and Sikaflex® paddle.
  • Mix for 3-5 minutes to achieve a uniform color and consistency. Scrape down sides of pail periodically. Avoid entrapment of air during mixing.
  • For prepigmented limestone base: just mix with low speed drill and Sikaflex® paddle without Color-pak.
