PARALOID™A-21LV是一种非常坚硬的甲基丙烯酸甲酯聚合物，具有增强的粘合性能。这种树脂与PARALOID™A-21相似，但与纤维素具有更好的相容性，并允许在喷雾粘度下具有更高的固含量。

PARALOID™ A-21LV is a very hard methyl methacrylate polymer with enhanced adhesion properties. This resin is similar to PARALOID™ A-21, but possesses better compatibility with cellulosics and allows for a higher solids content at spray viscosity.
