Features & Benefits
- CASE Ingredients Features
- Specific Features
- Because of its content of carboxyl groups, VINNOL® H 30/48 M adheres excellently to metal surfaces. VINNOL® H 30/48 M is a high vinyl acetate containing copolymer.
- It is therefore especially suitable as a cobinder for formulating flexible VINNOL®-paint and printing ink formulations.
- It is also highly recommended to reduce the sealing temperature in VINNOL®-based heat sealing lacquers.
- The solubility in various monomers enables to use VINNOL® H 30/48 M as an additive in solvent-free 100% systems to improve adhesion and pigment wetting or to reduce shrinking.
- It can also be used as a reactant or co-binder in two-pack systems. For example, it may be crosslinked with isocyanates, epoxy or melamine resins.

Processing
- VINNOL® H 30/48 M is generally used in dissolved form. Ketones, in particular, are excellent solvents for VINNOL® surface coating resins.
- In the case of VINNOL® H 30/48 M, esters, too, may be used as single solvents. Of the chlorinated hydrocarbons, methylene chloride and 1,2-dichloroethane are true solvents.
- Alcohols and aliphatic hydrocarbons do not dissolve VINNOL® H 30/48 M. Aromatic hydrocarbons may be combined to a limited extent with true solvents.
- VINNOL® H 30/48 M is also soluble in various monomers (e.g. styrene, methyl methacrylate, 2-ethylhexyl acrylate, 1,6-hexanediol diacrylate and others).
- VINNOL® H 30/48 M can be plasticized with monomeric and polymeric plasticizers such as phthalates, adipates, sebacates, citrates, phosphates, epoxides and chlorinated paraffins.
- VINNOL® H 30/48 M is fully compatible with all other VINNOL® surface coating resins. It also combines well with many acrylic polymers and ketone resins, as well as with some epoxides.
- Alkyd resins, nitrocellulose, polyvinyl acetates and polyvinyl butyrals are in general incompatible with VINNOL® H 30/48 M. We recommend always checking the compatibility of VINNOL® H 30/48 M with the polymer in question.
- The compatibility of VINNOL® H 30/48 M with pigments or colorants must be checked in preliminary tests. Certain pigments/colorants may produce thixotropic effects and/or impair adhesion. Care must be taken when using pigments containing zinc or cadmium because these catalyze the decomposition of VC copolymers at elevated temperatures. The same applies to iron-oxide pigments.
- Despite good inherent stability, it is necessary for some applications to stabilize coatings based on VINNOL® H 30/48 M against heat and/or UV light.
- Epoxy compounds often suffice to stabilize these coatings against low thermal impact. Where higher temperatures are involved, it is advisable to use calcium/zinc or organotin stabilizers.
- Outdoor applications require the additional use of UV stabilizers along with thermal stabilizers optimized for these conditions. To avoid risk of discoloration, contact with iron should be avoided both during the preparation of the solution and during subsequent storage of the product. VINNOL®-based surface coating compounds should be stored in coated containers.

- Properties
- VINNOL® H 30/48 M 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 30/48 M 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.
