摘要： A modeling method for minimizing the cure time and flow time of a thermoset in-mold coating for a molded article. The minimization of cure time is based on determining the cure time as a function of mold temperature and initiator level. The method for minimizing flow time is based on predicting the fill pattern for a specific geometry mold. The methods are used to reduce cycle time in the preparation of in-mold coated parts and reduce defects in the appearance of the coating.

摘要： Molded articles or substrates having an in-mold coating thereon are disclosed. The in-mold coated substrates are produced by a method wherein the flow of the in-mold composition onto the substrate can be selectively controlled. The molded articles can be preferentially coated in desired or predetermined areas with in-mold coating compositions by controlling the thickness or depth of various sections of the substrate. A molded article or substrate is provided with a removable in-mold coating containment flange which extends completely around the perimeter of a surface to be coated in order to substantially contain the in-mold coating within the mold cavity and on the desired area of a part before the coating has been cured.
