Evaluation of innovative low-volatile organic compound (VOC) industrial maintenance (IM) coatings. Report for April-September 1994
The paper discusses a field evaluation of the feasibility of using alternative low-volatile organic compound (VOC) coatings to replace higher-VOC coatings. The evaluation includes chemical, performance, and outdoor exposure testing. The feasibility of five alternative coatings for reducing pollution is considered. The coatings are compared to a standard coating that is being used in practice. Although outdoor exposure testing is not yet complete, available results indicate that all of the coatings have characteristics that could make them viable alternatives. For VOC emissions reduction, coating 4 (a two-component polysiloxane epoxy) was the best.
Pollution prevention methods in the surface coating industry
Abstract The surface coating industry is rapidly changing to meet environmental and economic pressures. Some of the changes include new formulations which meet environmental regulations, higher performance finishes with improved properties, continued development of solventless technologies such as powder coatings and radiation curable coatings, and new application methods with improved transfer efficiencies. These changes will be accelerated by the 1990 amendments to the U.S. Clean Air Act. These new enviromnental laws will require industry through the Environmental Protection Agency (EPA) and state and local agencies to further reduce emissions of volatile organic compounds (VOCs) which are contributors to ozone formation in the lower atmosphere. The focus of this paper will be to examine the paints and coatings industry and those pollution prevention methods that are being applied to meet these environmental pressures. It will review the life cycle of paints and coatings; from its inception in the manufacturing facility to its ultimate application and disposal. It will also review developing low VOC technologies that are being considered worldwide to comply with increasing VOC regulations.
Supercritical fluid spray application technology : a pollution prevention technology for the future
On examine les possibilites d'utilisation de CO 2 supercritique en remplacement des solvants organiques volatils pour le depot de peinture par pulverisation. On n'utilise qu'une faible quantite de solvants pour la coalescence et l'etalement du film. Ce procede peut etre applique au pistolage pneumatique ou sans air. On discute de la reduction de viscosite, de la formulation des revetements, des equipements de pistolage et des avantages du point de vue de la compatibilite avec l'environnement.
