Methods for making coating compositions having predetermined voc contents, methods for making systems for producing such coating compositions, and temperature adjusters for making such coating compositions

A method for making a system for producing a coating composition having a predetermined VOC content, the method comprising the steps of:

• selecting an ambient temperature range at which the coating composition will be applied;
• selecting an exempt solvent, a nonexempt solvent, and a resin from which to form a temperature adjuster used to make the coating composition, wherein the exempt solvent and the nonexempt solvent are selected based on their rates of evaporation within the ambient temperature range;
• determining amounts of the exempt solvent, the nonexempt solvent, and the resin so that the temperature adjuster will be formed with the predetermined VOC content or less;
• mixing the amounts of the exempt solvent, the nonexempt solvent and the resin to form the temperature adjuster having the predetermined VOC content or less, wherein the temperature adjuster has no less than about 1% solid and wherein the temperature adjuster is a first component of the system;
• and
• repeating the selecting steps, the determining step, and the mixing step to make an additional temperature adjuster suitable for making an additional coating composition, wherein the additional temperature adjuster is an additional component of the system.

A temperature adjuster for making a coating composition, the coating composition having a predetermined VOC content and comprising no less than about 1% solids, the temperature adjuster formed according to a method comprising the steps of:

• selecting an ambient temperature range at which the coating composition will be applied;
• selecting an exempt solvent, a nonexempt solvent, and a resin from which to form the temperature adjuster used to make the coating composition, wherein the exempt solvent and the nonexempt solvent are selected based on their rates of evaporation within the ambient temperature range;
• determining amounts of the exempt solvent, the nonexempt solvent, and the resin so that the temperature adjuster will be formed with the predetermined VOC content or less;
• mixing the amounts of the exempt solvent, the nonexempt solvent and the resin to form the temperature adjuster having the predetermined VOC content or less.
