摘要
人们对符合环保要求涂料的质量愈来愈重视,因此对合成聚酯粉末涂料用树脂的人员提出了越来越严格的要求。但是由于可选用的单体种类有限,配方人员设计高性能树脂的能力受到了限制。一旦一些用于粉末涂料树脂的新型单体问世,人们立即要了解其对于玻璃化转变温度Tg、熔融粘度的影响,因为这些参数表征了粉末涂料的稳定性和固化时的流动性。本文将重点讨论最近用于合成粉末涂料用树脂的一些二元醇和二元酸对这些重要参数的影响。
An increased emphasis upon the quality of compliant coatings has placed more stringent demands upon formulators of polyester powder coating resins. The ability of formulators to design higher performance resins is limited by the number of useful monomers that are available.When new monomers are considered for powder coating resins, attention is immediately focused upon the effects they impart to the glass transition temperature, Tg, and the melt viscosity, as key indicators of powder coating stability and flow ability during cure. This paper addressed these important variables for a number of glycols and diacids recently introduced for use in polyester powder coating resins.
