Butvar® Dispersions - Butvar Polyvinyl Butyral (PVB) Resin

Butvar® Dispersions
Butvar® Dispersions are a family of stable aqueous emulsions of plasticized polyvinyl butyral
(PVB) that can be formulated as a performance enhancing additive or as a primary resin system
in waterborne coatings. These film forming emulsions are cross-linkable with a variety of resin
systems which allows formulators to gain the same widely known unique performance
characteristics of PVB resins - adhesion, toughness and flexibility – to optimize performance
while targeting for low VOC formulary content.
