Vinnol H 14/36 copolymer of vinyl chloride and vinyl acetate 9003-22-9 Wacker Polyvinyl chloride (PVC) Polyvinyl acetate emulsions & derivatives (PVAc…) >> PVAc homopolymers ADHESIVE VINNOL® H 14/36 is a copolymer of vinyl chloride (VC) and vinyl acetate (VAc) with very low viscosity in solutions. Its main use is as a binder for surface coating compounds and adhesives.VINNOL® H 14/36 is a physically drying binder that forms a film when the solvent contained in the formulation has evaporated. Vinnol H 14/36 is a copolymer of vinyl chloride (VC) and vinyl acetate (VAc). Its main use is as a binder for surface coating compounds and adhesives. Vinnol® H 14/36 is a physically drying binder that forms a film when the solvent contained in the formulation has evaporated. Like all VC copolymers, Vinnol® H 14/36 is characterized by excellent toughness, permanent flexibility, abrasion resistance, low swelling in the presence of water, and low gas permeability. Coatings based on Vinnol® H 14/36 adhere well to absorbent, porous substrates such as paper, cardboard, textiles, concrete etc, as well as to PVC, without the use of further additives. On smooth substrates such as metal, it is advisable to use an adhesion promoter, such as a VC terpolymer containing carboxyl groups (eg, Vinnol® H 15/45 M). Films of Vinnol® H 14/36 are highly resistant to water. They also show excellent resistance to oil, grease, dilute aqueous acids, alkalis and saline solutions. Aromatic hydrocarbons and chlorinated hydrocarbons cause them to swell to varying extents. Vinnol® H 14/36 is resistant to aliphatic hydrocarbons, such as white spirit, and to alcohols. We will be glad to supply further information on request. Ketones and esters are the solvents most commonly used for Vinnol® H 14/36, while chlorinated hydrocarbons are only rarely used. Ketones are particularly good solvents for Vinnol® surface coating compounds. Esters are less efficient solvents than ketones. Chlorinated hydrocarbons such as methylene chloride and 1,2-dichloroethane will dissolve Vinnol® H 14/36, whereas tri- and tetrachloroethene will only cause it to swell. Alcohols and aliphatics are non-solvents for Vinnol® H 14/36. Vinnol® H 14/36 can be plasticized with either monomeric or polymeric plasticizers, such as: Phthalates Adipates Sebacates Citrates Phosphates Epoxides Chlorinated paraffins Always check the compatibility of Vinnol H 14/36 with a particular polymer. Vinnol® H 14/36 can be combined in any proportions with all other Vinnol® surface coating resins. It also shows good compatibility with a large number of acrylic polymers and ketone reins, and with some epoxides. Alkyd resins, nitrocelluloses, polyvinyl acetates and polyvinylbutyrals generally cannot be combined with Vinnol H 14/36. Pigments and fillers Vinnol® H 14/36 is compatible with most standard pigments. Please note that zinc and cadmium pigments catalyse the decomposition of VC copolymers at elevated temperatures. The same is true of iron oxide pigments. Although Vinnol® H 14/36 shows intrinsic heat and UV resistance, it may be necessary to stabilize the Vinnol®-modified surface coating compound in some cases. Epoxy stabilizers usually provide adequate heat resistance. If enhanced stability is required, we recommend organo-tin compounds. A combination of epoxy stabilizers and organo-tin compounds produces synergistic effects. For outdoor applications, it is advisable to add light-resistant UV stabilizers. In this case, light resistant heat stabilizers, such as sulfur free tin stabilizers should be used. To avoid risk of discoloration, contact with iron should be avoided both during preparation of the solution and during subsequent storage of the product. Vinnol® - based surface coating compounds should be stored in coated containers. Copolymer of vinyl chloride and vinyl acetate with very low viscosity in solutions. Used as a binder for adhesives. Offers good toughness, permanent flexibility, abrasion resistance, low swelling in the presence of water, low gas permeability.
