PVB Polyvinyl butyral resin
PVB structural formula：
INTETIA PVB resin can provide a range of excellent properties, such as adhesion, transparency, toughness,
and flexibility, when used in various industrial products. Due to the presence of hydroxyl functional groups,
INTETIA PVB resin can undergo crosslinking reactions with other resins such as phenolic resin, epoxy resin,
or amino resin in the thermosetting system; At room temperature curing system, INTETIA PVB resin can
undergo crosslinking reaction with isocyanates.
Application：
Safety glass film clip
Ceramic base material
Printing ink
Casting process of electronic ceramic components
Adhesive
Synthetic fiber base material
Coating Wash primer
Other applications.
