The hardener is mainly used with 2K car paint and 2K clear coat (varnish), because the paint group needs to undergo a cross-linking reaction with the hardener group to form a polymer, in order to improve the hardness of the paint film.
The hardener needs to have the function of weather resistance, yellowing resistance and chemical resistance. The solid content of varnish is different, so need to use with the matching hardener, that's because the solid content of curing agent is also different. The higher solid content of varnish, the higher solid of hardener, for example, when you use our MF280 clear coat, then you use with our MF282 hardener, when use our MF580 clear coat, use with MF582 hardener. The higher solid content, the higher hardness of paint film.
According to the drying speed, it is divided into fast drying, standard drying and slow drying hardener, which one to choose is depending to the environment temperature. If the temperature is 5~15℃, use fast-drying hardener, 15~28℃ use standard hardener, and 28~35℃ use slow-drying hardener.
How to use: the mixing ratio between main paint and hardener is 2:1, and the spraying method can be carried out according to the spraying method of the main paint.
