Plextol X 4319 n-butylacrylate PolymerLatex Acrylics/ Acrylates >> Butyl acrylate copolymers, BA ADHESIVE >> Hot-melt >> Pressure sensitive (HMPSA) PLEXTOL X 4319 is an aqueous emulsion of a thermoplastic acrylic polymer. Film properties Evaporation of the water above the minimum film-forming temperature leaves a clear, colourless and hydrophobic film, which is very soft, extremely tacky at room temperature and very slightly water-sensitive. The film is insoluble in water and partly soluble in organic solvents. PLEXTOL X 4319 can be used to produce self-adherent coatings on a variety of materials such as plastic sheeting, paper, textiles, sheet metal, glass,and tapes. can be used for the production of tapes. Aqueous emulsion of a thermoplastic acrylic polymer. Can be used for the production of tapes. Provides a soft and tacky film insoluble in water and partly soluble in organic solvents.
