Wacker Vinnol® H 40/55 Vinyl Chloride Copolymer
Categories:	Polymer; Thermoplastic; Vinyl (PVC)
Material Notes:	CAS NO. 9003-22-9 Product description: VINNOL® H 40/55 is a copolymer of approx. 62 wt.% vinyl chloride (VC) and approx. 38 wt.% vinyl acetate (VAc). Its main use is as a binder for surface coating compounds and printing inks. Properties: VINNOL® H 40/55 is a thermoplastic, physically drying binder that forms a film when the solvent contained in the formulation has evaporated. Like all VC copolymers, VINNOL® H 40/55 is extremely tough, showing permanent flexibility, abrasion resistance, little tendency to swell in the presence of water and low gas permeability. It is also highly resistant to oil, grease, dilute aqueous acids, alkalis and saline solutions, as well as to aliphatic hydrocarbons, such as white spirit, and alcohols. Special features: VINNOL® H 40/55 is a high vinyl acetate containing copolymer. It is therefore especially suitable as a cobinder for formulating flexible VINNOL®-paint and printing ink formulations. The solubility in various monomers enables to use VINNOL® H 40/55 as an additive in solvent-free 100% systems to improve adhesion and pigment wetting or to reduce shrinking. VINNOL® H 40/55 also shows a surprisingly good compatibility with ester soluble nitrocellulose resins and can be used for their modification. Application: Typical applications for VINNOL® H 40/55: Printing inks Heat-sealable lacquers Paper and film coatings Strippable lacquers Wood varnishes Masonry paints Road-marking paints Information provided by Wacker Chemie AG.
