Courtrai siccative white bottle of 75 ml Lefranc

This desiccant is lead-free and contains calcium and zirconium salts: this means that it has a gentle action on the colors while improving their hardening. Its coloring does not alter the light colors.

To be used with the utmost precaution: an excessive addition can be harmful and even counteract the effect of the desiccant itself (the average proportion is two / three drops for each nut of color).
