PARALOID™A-646树脂是一种非常硬的甲基丙烯酸甲酯聚合物，在MEK中以45％的固体含量提供。这种树脂是PARALOID™A-101的较低分子量类似物，允许使用较高固含量的配方，使涂料粘度更低，从而获得更高的光泽度和更好的回流。

PARALOID™ A-646 resin is a very hard methyl methacrylate polymer supplied at 45% solids in MEK. This resin is a lower molecular weight analog of PARALOID™ A-101, allowing for higher solids formulations, and enables coatings to be lower in viscosity for higher gloss and better reflow.
