How do you calculate pigment to binder ratios?

To calculate pigment to binder ratiOS, first determine the weight of the pigment and the weight of the binder in your formulation. The ratio is then calculated by dividing the weight of the pigment by the weight of the binder. For example, if you have 100 grams of pigment and 50 grams of binder, the pigment to binder ratio would be 100:50 or simplified to 2:1. This ratio helps in achieving the desired color strength and consistency in paints and coatings.
