As an example, if the factor is temperature … WebFeb 1, 2012 · A paint formulation certainly has measurable inputs – raw materials and amounts are an obvious example. The measurable outputs are performance parameters, be it scrub resistance, gloss, salt spray resistance, dry time, oven stability and so forth. Thus, by definition, DOE should be a viable formulating tool for the coatings chemist.
