How to Get Best Results from Arctic 2CNS Sikaflex Sika Sealant

When dealing with cold-weather construction projects, finding sealants that can properly cure and seal can be a major challenge!  Fortunately, the Sika Sealant Arctic 2CNS Sikaflex is fully capable of getting the job done, remaining workable and gun able at temperatures as low as 15F (-9.5C), and once cured, can maintain its seal at even lower temperatures.

How Arctic 2CNS Sikaflex Sika Sealant Holds Firm Even in Bitter Cold

Arctic 2CNS Sikaflex is a highly elastic two-component polyurethane sealant specifically designed for arctic weather conditions and applications.  It doesn’t sag, even in wide joints, while offering superior cut and tear resistance – which is important in situations where there may be high winds with debris or ice shards.

Its chemical cure properties allow it to go to greater depths as well, and it’s intended for joints at least 1/4″ deep.  It comes in 35 standard colors, and it’s also compatible with water, oil, and rubber-based paints, allowing it to match nearly any architecture.

Arctic 2CNS works well in both vertical and horizontal applications and can adhere to almost any common construction substrate.  It can even be used in submerged environments, such as reservoir joints.

Proper Usage of Arctic 2CNS Sikaflex Sika Sealant

Arctic 2CNS remains easy to mix and use, even when temperatures are well below freezing.  The process is simple.  First pour Component A into a pail, followed by Component B, and then the ColorPak if needed.  It should be mixed mechanically but slowly, at 400-600 RPM.  Mixing should take around 3-5 minutes until it achieves a uniform color and consistency.  Be sure to scrape down the sides of the pail periodically to ensure that all of the product is properly mixed.

Don’tover-mix and be sure to keep mixing speeds slow to avoid air entrapment.

Once mixed, it can be loaded directly into a bulk gun or onto a follower plate loading system.  The nozzle of the gun should be placed at the bottom of the joint, and the joint should be fully filled.  You want to keep the nozzle within the sealant to reduce the chances of air becoming trapped.  Also, avoid layering the sealant.
