Product 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.
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.
