Notes:
IPN powder coatings were prepared which were composed of (A) a pendant double bond-containing acrylic resin made by reacting m-isopropenyl-α-α-dimethylbenzyl isocyanate (TMI) and a hydroxyl-containing acrylic resin and (B) a bisphenol type epoxy resin of high molecular weight cured by means of a carboxylic acid-containing acrylic resin. Crosslinking kinetics studies were carried out by using a computerized differential scanning calorimeter (DSC). A computer program was designed to simulate the curing reactions of the IPN powder coatings by using the individual kinetic parameters obtained from DSC. The simulated results from the computer program are very close to the results from experimental thermograms (by DSC). Therefore, this methodology provides an efficient tool to simplify and predict kinetic studies of crosslinking reactions in current or new IPN powder coating systems.
