16 APPENDIX
16.1 CONVERSION OF THE MIXING RATIO SPECIFICATIONS
It is very important that the data sheets of the paint supplier are available, so that the correct
mixing ratio can be entered.
Some lacquer manufacturers state the mixing ratio by weight, others by volume or
ratio.
Since the 2K system measures volumetrically, we need the specication in volume.
Conversion of mixing ratio from gravimetric to volumetric:
Example:
10 Parts of component A by weight and
1 Parts of component B by weight
or
10g Component A
1 g Component B
or parts by weight 10:1
or 10:1 per weight (A gravimetric : B gravimetric)
The density or specic volume of the components A and B must be known or be
determined beforehand.
