在欧洲，建筑铝的粉末饰面现在占建筑饰面的30%以上。本文介绍了两个机会领域，这两个领域在北美和世界范围内为建筑粉末的使用提供了巨大的增长潜力。讨论了显著提高外部耐久性的粉末系统的最新发展。重点放在使用加速风化作为评估外部耐久性的手段上，并对比较方法进行了评述。此类开发的一个里程碑是生产符合美国建筑制造商协会AAMA 605.2-90性能标准的粉末。还研究了粉末应用于板材产品的替代技术。 在壁板和覆层市场，平板应用方法为建筑粉末C的使用提供了巨大的扩展潜力

POWDER FINISHING OF ARCHITECTURAL ALUMINUM NOW ACCOUNTS FOR OVER 30% OF ARCHITECTURAL FINISHES IN EUROPE. THIS PAPER INTRODUCES TWO AREAS OF OPPORTUNITY WHICH OFFER SIGNIFICANT POTENTIAL FOR GROWTH IN THE USE OF ARCHITECTURAL POWDERS, BOTH IN NORTH AMERICA AND WORLDWIDE. THE LATEST DEVELOPMENTS OF POWDER SYSTEMS WITH SIGNIFICANTLY INCREASED EXTERIOR DURABILITY ARE DISCUSSED. EMPHASIS IS PLACED ON THE USE OF ACCELERATED WEATHERING AS A MEANS OF ASSESSING EXTERIOR DURABILITY, AND COMPARATIVE METHODS ARE REVIEWED. A LANDMARK IN SUCH DEVELOPMENT IS TO PRODUCE A POWDER THAT COMPLIES WITH THE AMERICAN ARCHITECTURAL MANUFACTURERS' ASSOCIATION AAMA 605.2-90 PERFORMANCE STANDARD. ALTERNATIVE TECHNIQUES FOR POWDER APPLICATION TO SHEET PRODUCTS ALSO ARE EXAMINED. IN THE SIDING AND CLADDING MARKET, FLAT BED APPLICATION METHODS OFFER GREAT POTENTIAL FOR EXPANSION IN THE USE OF ARCHITECTURAL POWDER C
