Usage

Description

BISPHENOL A DIMETHACRYLATE, also known as 2,2-bis(4-Methacryloxy)phenyl)propane, is a bisphenol derived from bisphenol A and two molecules of methacrylic acid. It is a white to slightly yellow crystalline powder with unique chemical properties that make it suitable for various applications.

Uses

Used in Dental Industry:
BISPHENOL A DIMETHACRYLATE is used as a key component in dental restorative composite and adhesive materials for its ability to enhance the mechanical properties and durability of these materials. Its incorporation into dental composites and adhesives improves their overall performance, making them more resistant to wear and providing better adhesion to tooth structures.

DENTAL COMPOSITION AND COMPOSITE RESIN

A dental composition of the present invention includes: a polymerizable monomer component (A); and an amorphous filler (B) having an average particle size of 1 to 20 μm and including silica-based fine particles and coatings of an oxide that cover the surfaces of the silica-based fine particles. The oxide contains a zirconium atom, a silicon atom, and an oxygen atom. The dental composition contains 20 to 500 parts by weight of the filler (B) per 100 parts by weight of the polymerizable monomer component (A). The dental composition has a viscosity of 10 to 800 Pa·s. It is preferable that the filler (B) contain spherical particles, and that the percentage of the spherical particles in the filler (B) be at least 60%.
