Composite Wetting Resin is a 45% filled, light-cured, liquid resin. It is significantly superior to single-component adhesives, which contain solvents and inhibit composite polymerization.
Use Composite Wetting Resin during incremental layering of composite materials. We recommend it be used when the oxygen inhibition layer has been removed or disturbed (e.g., washing the composite surface following contamination). Composite Wetting Resin may be placed on the composite surface if it has become dry while contouring composite. Use Composite Wetting Resin on an instrument or brush to enhance glide. Composite Wetting Resin greatly facilitates adaptation of the composite restoration and preparation.
"I use Composite Wetting Resin instead of a bonding agent to facilitate adaptation of composite. Bonding agents often contain acetones or alcohols that can cause the resins and fillers in the composite to separate, which weakens the surface of the restoration. They also may change the composite's shade after curing."
