对耐用涂层的需求显而易见。它们提供了抵御导致结构腐蚀和退化的元素的第一道防线，并为产品提供了审美吸引力。对更高固体分的涂料的需求日益增加，这种涂料利用具有更高功能性的低分子量主链，再加上更低的固化温度，这通常会给涂料配方制定者带来保持涂料耐久性的问题。通常，使用光稳定剂和热稳定剂可以显著提高高固体分涂层的耐久性。 本文讨论了聚合物降解的一般机理、降解对涂层性能的影响、稳定添加剂的类型及其作用和机理。给出了稳定化的例子。本文指出了稳定添加剂的使用如何作为一种重要的工具来提供

THE NEED FOR DURABLE COATINGS IS CLEAR. THEY PROVIDE THE FIRST LINE OF DEFENSE AGAINST THE ELEMENTS WHICH CAUSE STRUCTURAL CORROSION AND DEGRADATION AS WELL AS PROVIDING AESTHETIC APPEAL TO PRODUCTS. THE INCREASING NEED FOR HIGHER SOLID COATINGS WHICH UTILIZE LOWER MOLECULAR WEIGHT BACKBONE WITH HIGHER FUNCTIONALITY COUPLED WITH LOWER CURING TEMPERATURES HAS GENERALLY PRESENTED PROBLEMS MAINTAINING COATING DURABILITY FOR COATING FORMULATORS. OFTEN THE DURABILITY OF HIGHER SOLIDS COATINGS CAN BE DRAMATICALLY IMPROVED BY THE USE OF LIGHT AND HEAT STABILIZERS. THIS PAPER DISCUSSES GENERAL MECHANISMS FOR POLYMER DEGRADATION, MANIFESTATIONS OF DEGRADATION ON COATING PERFORMANCE, TYPES OF STABILIZING ADDITIVES, AND THEIR FUNCTIONS AND MECHANISMS. EXAMPLES OF STABILIZATION ARE PRESENTED. THE PAPER INDICATES HOW THE USE OF STABILIZING ADDITIVES CAN FUNCTION AS AN IMPORTANT TOOL TO PROVIDE TO TH
