POWDER-LIQUID DENTAL CURABLE MATERIAL KIT

摘要

This powder-liquid dental curable material kit is composed of (A) a liquid material and (B) a powder material, and is characterized in that: the liquid material (A) contains (a1) a radically polymerizable (meth)acrylic monomer, (a2) an organic halogen compound and (a3) a radical chain transfer agent; the powder material (B) contains (b1) non-crosslinked resin particles, (b2) the pyrimidinetrione compound and (b3) the organic metal compound; and (Z) a peroxide is blended in the liquid material (A) and/or the powder material (B). This curable material kit is capable of reducing the heat generation during the curing of a curable material that is a mixture of the liquid material (A) and the powder material (B), and is not susceptible to excessive increase in the curing time even if the curable material is cured by a brush-on method, thereby ensuring an adequate curing time both in a brush-on method and in a kneading method.
