Butvar Polyvinyl Butyral (PVB) Resins

    Butvar polyvinyl butyral resins are recognized as the binder of choice in the processing of ceramic tape cast materials. The resin gives excellent green strength and flexibility to the ceramic tape. It is compatible with many common solvents and plasticizers and burns out cleanly during sintering.

    Butvar resins also are used as binder media in thick film processing. Butvar resins are formulated in the solvent vehicle used to deposit the circuit pattern on the ceramic surface. The primary advantages of using Butvar resins are their solubility in a wide range of solvents and uniform adhesion to conductive metals.
