CC—4型BA复合树脂研究

Study of the CC-4Type BA Composite

由树脂液体、用于充填的A粉以及用于粘结的B粉组成CC—4型复合树脂。该复合树脂含有二甲基丙烯酸酯单体和二异氰酸酯改性EAM新型基质树脂(UDMA)。不含MMA;其物理机械性能优于临床常用的粉液型复合树脂;并具有良好的粘接性和储存稳定性。

The CC-4type BA composite was prepared with a resin liquid and two powders, powder A for filling and powder B for bonding. The composite contains a dimethacrylate monomer and a new matrix resin which is EAM resin modified with diisocyanate (UDMA), and it contains no MMA. The physical mechanical properties of the new composite are better than that of powder-liquid composites which are widely used in clinic. The composite also has the advantages of good adhesiveness and good stability for storage.
