Vinnol E 22/48 A copolymer of vinyl chloride and an acrylate 114653-42-8 Wacker Acrylics/ Acrylates Polyvinyl chloride (PVC) ADHESIVE VINNOL® E 22/48 A is a copolymer of vinyl chloride (VC) and an acrylate, and contains hydroxyl groups. VINNOL® E 22/48 A is a physically drying binder that forms a film when the solvent contained in the formulation evaporates. This binder is also used frequently in two-pack systems. VINNOL® E 22/48 A is a physically drying binder that forms a film when the solvent contained in the formulation evaporates. This binder is also used frequently in two-pack systems. Like all VC copolymers, VINNOL® E 22/48 A is characterized by excellent toughness, permanent flexibility, abrasion resistance, low swelling in the presence of water, and low gas permeability. Films of VINNOL® E 22/48 A 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 ® E 22/48 A is resistant to aliphatic hydrocarbons, such as white spirit, and to alcohols. We will be glad to supply further information on request. Ketones, esters and chlorinated hydrocarbons are the solvents most commonly used for VINNOL® E 22/48 A, which contains hydroxyl groups. Ketones are particularly good solvents for vinyl chloride copolymers; VINNOL® E 22/48 A dissolves rapidly, for instance, in acetone, methyl ethyl ketone, methyl isobutyl ketone and cyclohexanone. Esters, such as ethyl and butyl acetate 98/100, are somewhat less efficient solvents than ketones. Alcohols, aliphatic hydrocarbons and aromatic solvents do not dissolve VINNOL® surface coating resins. Adhesives By virtue of their chemical composition, VINNOL® surface coating resins containing hydroxyl groups produce highly flexible films. Their flexibility can be increased further by adding plasticizers (external plasticization). VINNOL® resins of the E/A range are compatible with a large number of plasticizers, such as: Phthalates Adipates Sebacates Citrates Phosphates Epoxides Chlorinated paraffins VINNOL® E 22/48 A can be combined with all other VINNOL® surface coating resins. It is also compatible with a large number of combination resins. Always check the compatibility of VINNOL ® E 22/48 A with the polymer in question. VINNOL® E 22/48 A shows good compatibility with the pigments and fillers normally used in the paint industry, the presence of the free hydroxyl groups resulting in excellent pigment wetting properties. In stoving finishes, care must be taken when use is made of pigments containing iron and zinc. Preliminary tests are essential, since there is a danger of discoloration. Although VINNOL® E 22/48 A 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. VINNOL® E 22/48 A is processed according to all methods commonly used in the paints and printing inks industry. 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 an acrylate, and contains hydroxyl groups. Can be used in two-pack adhesives. Offers good toughness, permanent flexibility, abrasion resistance, low swelling in the presence of water, and low gas permeability. Provides high resistance to water, good resistance to oil, grease, dilute aqueous acids, alkalis and saline solutions.
