Butvar Polyvinyl Butyral (PVB) Resin Technical Information
Butvar resin was pioneered by Solutia in the 1930s as the key ingredient for automotive safety glass interlayers. It still enjoys widespread use in automotive and architectural applications for laminated safety glass.
Solutia offers six grades of Butvar resin that cover a broad range of chemical and physical properties. These resins are generally well suited either as a major ingredient of a formulation or in smaller quantities to enhance the properties of other resins.
Some of the applications in which Butvar is a vital ingredient include:
- Ceramic binders
- Dry toners
- Wood coatings
- Wash primers
- Composite fiber binders
- Structural adhesives
- Other diverse uses
