控制表面缺陷用流动改性剂

FLOW IMPROVER FOR CONTROL OF THE SURFACE DEFECTS OF COATINGS

动改性剂在涂料中起着许多作用，主要用于减轻、消除涂膜的表面缺陷，改善涂膜外观。在涂料的生产和成膜过程中它们有助于颜料的分散，改善其对底材的润湿，促进流动流平，控制缩孔、鱼眼、桔皮和针孔等等。着重评述了流动改性剂在控制粉末涂料表面缺陷中所起的作用。

Flow improvers play many roles in paint formulation, and particularly to reduce and eliminate the film defects and improve the film appearance They will be helpful during the paint production and film-forming process, to help the dispersing of pigments, improve the wetting on substrates, and flow and leveling, control the film defects, such as cratering, fish eyes, orange peel and pinholes This paper is focused on the discussion of the functions of flow improvers in powder coatings
