To achieve a durable and attractive finish, it helps to understand the differences between 1K and 2K paints, including 2K Air-Dry aerosols, and how hardeners affect curing.
1K (one-component) paint cures by air drying and does not require an activator. It is quick to use and well suited to areas with low wear, for example higher cladding panels that are rarely touched.
2K (two-component) paint uses a hardener to trigger a chemical reaction that cures the coating. The result is a tougher, more resilient finish that performs better on surfaces exposed to frequent handling or high traffic.
1K paints are generally faster to dry and come ready to spray. By contrast, 2K aerosols must be activated before use. Once the internal hardener is activated, the can should be used within about eight hours. Because many 2K systems use an isocyanate hardener, suitable PPE is essential. We strongly recommend a respirator rated for paint vapours, protective gloves and eye protection when spraying 2K products.
Both 1K and 2K coatings offer good heat resistance, typically in the range of 160 to 190 °C.
2K Air-Dry aerosols use a non-isocyanate hardener, often called a 2K Air-Dry Converter (2K ADC). This allows traditional 2K formulations to cure without forced drying while retaining many of the performance benefits associated with 2K systems.
2K Air-Dry is a strong choice for customers who want 2K-level performance without the health risks that come with isocyanates. It also improves drying times and, once filled, offers a longer usable shelf life. In many cases the product remains usable for at least 12 months, which is cost effective for repeat work.
These aerosols perform well on a wide range of substrates, including metal, fibreglass, uPVC and wood. If you need guidance on a specific project or substrate, our paint specialists are happy to help.
