What is the difference between 1K and 2K paint?

The difference between 1K and 2K paint is huge! There are many differences between the two types of paint. It depends on the application which type of lacquer is the best choice for you. The main differences between 1K and 2K lacquer are: 1K lacquer is known as fast-drying paint. Due to the 2 components, a 2K lacquer does not dry as quickly. The paint is thicker so the drying time of 2K lacquer is longer than for 1K. 1K lacquer can be made in any colour, including solid, metallic and pearlescent lacquer. A 2K lacquer can only be made in solid colours. No clear coat is needed over 2K lacquer. The hardener makes 2-component lacquer so hard that you do not need to spray a clear coat over it. A 1K lacquer always requires a clear coat for good protection against external influences. 1K lacquer can be stored airtight at room temperature after use. A 2K lacquer hardens due to the hardener you have added to the paint. This is why a 2-component lacquer can be kept for 24 hours and then thrown away.
