Polyvinyl Butyral |
Product InformationChemical Name Polyvinyl Butyral (PVB Resin)CAS # 63148-65-2Formula H2(C8H14O2)nMelting point 135-149cSpecific gravity 1.1 (20C)
Description PVB Resin is fine-grained, free-flowing white powder. PVB is produced by reacting polyvinyl alcohol (PVOH) with butyraldehyde in an acid medium (acetalization reaction). It is a thermoplastic polymer showing good mechanical properties, good flexibility, optical clarity and excellent adhesion to different substrates. It is compatible with a broad range of other resins and shows good solubility in different organic solvents. PVB can be used in a manifold of applications such as industrial coatings, laquers, primers, printing inks, adhesives, fiber binders, temporary binder for ceramics, Film for safety glass, etc. Application Binder for coatings (adhesion promotion/corrosion protection primers, shop primers,wash primers, stoving enamels, varnishes and lacquers for different substrates).Binder for printing inks. Co-binder for powder coatings. Temporary binder for ceramics. Binder for textile printing and non-woven. Wetting agent for grindings of organic pigments.Adhesives,pressure-sensitive adhesives and hotmelts etc. |
