Powder-liquid dental curable material kit

摘要

A powder-liquid dental curable material kit composed of (A) a liquid material and (B) a powder material, wherein 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) a pyrimidinetrione compound and (b3) an organic metal compound; and (Z) a peroxide is blended in at least one of the liquid material (A) and the powder material (B). This curable material kit is capable of reducing the heat generation during the curing of a curable material which is a mixture of the liquid material (A) and the powder material (B) and is not susceptible to the excessive prolongation of the curing time even when the curable material is cured by a brush-on technique, thereby ensuring an appropriate curing time for both of a brush-on technique and a kneading technique.

主权项

1. A powder-liquid dental curable material kit composed of a liquid material (A) and a powder material (B) and including a combination of an organic halogen compound, a pyrimidinetrione compound and an organic metal compound as a radical polymerization initiator, wherein
the liquid material (A) contains a radically polymerizable (meth)acrylic monomer (a1), the organic halogen compound (a2) and a radical chain transfer agent (a3); 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 contained in at least one of the liquid material (A) and the powder material (B), the peroxide serving as an oxygen source, and being contained in an amount of less than 0.5 parts by mass per 100 parts by mass of the sum of the liquid material (A) and the powder material (B).
