Sikaflex®-2c NS Arctic
Two-component, non-sag, polyurethane elastomeric sealant for arctic weather applications
Sikaflex®-2c NS Arctic is a 2-component, premium-grade, polyurethane based, elastomeric sealant formulated for cold weather applications. It is principally a chemical cure in a non-sag consistency. Available in a wide range of architectural colors with convenient color paks. Meets ASTM C-920, Type M, Grade NS, Class 25, use T, NT, M, G, A, O and Federal Specification TT-S-00227E, Type II, Class A. Meets CAN/CGSB 19.24 - M90.
- Easy to mix, gun, tool down to 15F
- At extreme cold temperatures the material will continue to be workable, gunable and toolable
- Chemical cure allows the sealant to placed in greater depths for non-moving joints/cracks
Usage
- Intended for use in all properly designed working joints with a minimum depth of 1/4 inch.
- Ideal for vertical and horizontal applications.
- Adheres to most substrates commonly found in construction.
- Mixable and placeable at temperatures as low as 15 F
- Submerged environments, such as canal and reservoir joints.
- An effective sealant for use in Exterior Insulation Finish Systems (EIFS).
