the resin matrix component of composite is dimethacrylate, a fluid-like material also referred to as:
BIS-GMA
Bis-GMA (Bisphenol A ethoxylate dimethacrylate) is the resin matrix component of composite that is a fluid-like material. It is the most commonly used resin matrix in dental composites due to its high strength and wear resistance. Bis-GMA has a low viscosity, which makes it easy to mix with the other components of the composite and allows it to flow easily into the preparation. Bis-GMA is a tri-functional monomer, which means that it can form cross-links with other monomers during the curing process, resulting in a strong and durable composite material.
