Composite wetting resin is a light-curing, liquid resin. It is significantly superior to single-component adhesives that contain solvents and inhibit the polymerization of composites. Use wetting resin when layering composite materials. Composite wetting resin can be applied to the composite surface if it has dried during contouring of the composite. Use wetting resin on an instrument or brush to improve glide. The resin greatly facilitates the application of the composite restoration and preparation.
