Stable phenolic resin polymer dispersions having low free aldehyde content

Abstract:

Stable dispersions of phenolic resins, particularly bisphenol-A/formaldehyde resins, for use in e.g., baking enamels, coatings, adhesives, binders, etc., are disclosed. The dispersions have low levels (e.g.,

Abstract(Chinese):

公开了用于例如烘烤搪瓷，涂料，粘合剂，粘合剂等的酚醛树脂，特别是双酚A /甲醛树脂的稳定分散体。分散体具有低水平（例如，<0.1重量％）的游离醛，从而减少与醛排放相关的环境危害。在制备过程中使用三聚氰胺作为醛清除剂可获得低游离醛水平。现在已经发现，与其它醛类清除剂相反，三聚氰胺对分散稳定性没有不利影响，干扰后续加工操作或者对最终树脂产品质量（例如，固化后）产生负面影响。
