1K Coating VS 2K Coatings - Information On The Different Paint Types

1K paint is less hard-wearing than the 2K alternative. 1K paint is more suitable for items and areas less prone to potential scratches and general wear and tear such as higher cladding panels on a building that do not frequently come into contact with day to day touching and potential damage. 2K paint provides a harder wearing coat more suitable for surfaces that may come into contact with day to day use and heavy access areas.

1K paint has a faster drying time compared to 2K paint and will air dry. This means that the paint does not require an activator to dry, unlike the 2K/Pack alternative. 1K/Pack spray paints are ready to spray without activation of the self-contained 2K hardener found in the base of the aerosol can.

1K paints typically dry's faster than 2K paints. 2K means an activator is required to dry/cure, sometimes referred to as a hardener. Once the hardener has been activated, you have up to 8 hours to apply the contents before the can becomes unusable. The hardener works by chemically reacting with a catalyst which sets hard to form a very tough finish. An isocyanate hardener is used, so a respirator, gloves and goggles should be used at all times when using 2K aerosols for general health and safety concerns.

Both our 1K and 2K paints have a heat resistant, between 160 - 190 degrees Celsius.
