4-methacryloxyethyl trimellitic anhydride is an acidic monomer that can serve as a reactive primer in dental adhesive systems. 4-META is a high performance monomer that interacts with the tooth substrate, creating excellent adhesive bonds to dentin and enamel. The structure contains two functional groups — a hydrophilic group and a hydrophobic group "bridging" the gap between highly polar and non-polar surfaces.
