Abstract
A method for reducing residue formation caused by volatile materials during the curing of powder coating compositions which includes the steps of applying different powder coating compositions to separate bases; placing each coated base in a separate extraction chamber; placing each separate extraction chamber in a curing oven; heating the coated base in its respective extraction chamber in the curing oven to curing temperature to cure the coating composition, and simultaneously flowing a stream of air through the respective extraction chamber to capture volatile emissions from the volatile materials in the air stream during the curing process; simultaneously flowing the respective stream of air out of the curing oven and chilling the stream to condense the volatile emissions from each of the compositions to a collectable form; determining the quantity of the emitted product from each of the compositions; and comparing the quantity of emitted product from each of the compositions to determine the composition that produced the least emissions.
