Abstract
A method of making a system for producing coating compositions having a predetermined VOC content includes preparing a paint comprising a resin and a solvent and having the predetermined VOC content or less. Temperature adjusters are prepared containing a resin and having the predetermined VOC content or less. Each temperature adjuster includes a different solvent or a different amount of a solvent compared to the others such that each of the coating compositions formed from one of the temperature adjusters is suitable for application within an ambient temperature range based on a rate of evaporation of the solvent within the ambient temperature range. Each temperature adjuster has no less than 1 wt. % solids based on the total weight of the temperature adjuster. The paint and the temperature adjusters are provided together as the system.
