Sikaflex-444 Rapid

Sikaflex®-444 Rapid is a one component, polyurethanebased sealant that when mixed with Sikaflex-444 Rapid Booster cures to become a complete bead of rubber that can be opened to vehicular traffic in approximately 4 hours. Sikaflex®-444 Rapid will cure without Sikaflex444 Rapid Booster, but the cure speed will be significantly reduced. Sikaflex®-444 Rapid is principally a moisture cured sealant with a semi-self-leveling consistency that can be applied to slopes as great as 20%. Sikaflex®-444 Rapid meets ASTM C920 Type S, Grade NS, Class 35, Use T, NT, M, G, A & O, and Federal Specification TT-S-00230C Type II, Class A.

Characteristics & Advantages

  • Cures in approximately 4 hours and capable of receiving vehicular traffic when mixed with Sikaflex®444 Rapid Booster. 
  • Semi-self-leveling consistency; capable of handling up to a maximum 20% slope. 
  • Will fully cure more slowly if Sikaflex®-444 Rapid Booster is not added. 
  • Capable of +/- 50% movement in certain well-designed joints based on actual field conditions. 
  • High elasticity with a tough, durable, flexible consistency. 
  • Exceptional cut and tear resistance. 
  • Exceptional adhesion to most substrates without priming. 
  • Easy to mix. 
  • Jet fuel resistant.
