Pulpdent's PolyCarb Water-Set Cement has polyacrylic acid incorporated into the powder; simply add water to activate the polycarboxylate cement. It is ideal for temporary and permanent cementation of crowns, bridges, inlays, and orthodontic brackets, and as a hard base under all types of restorations. The thick mixture provides optimum flow characteristics, when compared to zinc phosphate cement; this allows for easy clean-up of excess material.
