ACRONAL V 278
ACRONAL V 278
ACRONAL® V 278 is an aqueous dispersion for the manufacture of building adhesives and sealants. This dispersion is based on acrylicester copolymer that also contains acrylonitrile.
ACRONAL V 278 is used as a binder for the manufacture of dispersion-based sealants. Sealants formulated with this material are distinguished by their high resilience and their high flexibility at low temperatures. ACRONAL V 278 can also be used to manufacture adhesives for floor and wall coverings, such as carpets and PVC. These adhesives have a high initial tack and form a very heat-resistant bond.
