VINNOL® H 40/60

VINNOL® H 40/60 is a copolymer of approx. 61 wt.% vinyl chloride (VC) and approx. 39 wt.% of vinyl acetate (VAc).

 

Its main use is as a binder for surface coating compounds and printing inks.


Eigenschaften

VINNOL® H 40/60 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 40/60 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 40/60 is a vinyl acetate-rich VC 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 40/60 as an additive in solvent-free 100% systems to improve adhesion and pigment wetting or to reduce shrinking.

 
VINNOL® H 40/60 also shows certain compatibility with ester-soluble nitrocellulose resins up to a mixing ratio of 50/50 and can be used for their modification.

 

Typical applications for VINNOL® H 40/60:

  • Printing inks
  • Paper and film coatings
  • Strippable lacquers
  • Heat-sealable lacquers
  • Wood varnishes
  • Masonry paints
  • Road-marking paints

 

 

Processing

VINNOL® H 40/60 is generally used in dissolved form. Ketones, in particular, are excellent solvents for VINNOL® surface coating resins. In the case of VINNOL® H 40/60, esters, too, may be used as single solvents. Of the chlorinated hydrocarbons, methylene chloride and chloroform are true solvents.
Aromatic hydrocarbons have a swelling effect but may be combined to a limited extent with true solvents up to 50%. Alcohols and aliphatic hydrocarbons do not dissolve VINNOL® H 40/60.

 

VINNOL® H 40/60 is also soluble in various monomers (e.g. styrene, methyl methacrylate, 2-ethylhexyl acrylate, 1,6-hexanediol diacrylate, and others).

 

VINNOL® H 40/60 can be plasticized with monomeric and polymeric plasticizers, such as phthalates, adipates, sebacates, citrates, phosphates, epoxides, and chlorinated paraffins.

 
VINNOL® H 40/60 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. Ester soluble nitrocellulose is limited compatible, alkyd resins, polyvinyl acetates and polyvinyl butyrals are in general incompatible with VINNOL® H 40/60. We recommend always checking the compatibility of VINNOL® H 40/60 with the polymer in question.

 

VINNOL® H 40/60 shows good compatibility with pigments routinely used in the coatings industry. 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 40/60 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 resins should be stored in coated containers.

Das Produkt kann für Anwendungen mit Lebensmittelkontakt gemäß FDA 21 CFR §175.105 und §175.300 eingesetzt werden.

Informationen zur Bewertung hinsichtlich weiterer Regularien im Bereich Lebensmittelkontakt können über unsere Kundenbetreuer und Vertriebsgesellschaften angefordert werden.

Wird das Produkt in anderen Anwendungen als den aufgeführten Anwendungen eingesetzt, liegen Auswahl, Verarbeitung und Verwendung des Produktes in der alleinigen Verantwortung des Abnehmers. Dabei sind alle gesetzlichen und sonstigen Regelungen zu berücksichtigen.

Verpackung / Gebinde

VINNOL® H 40/60 is packed in 25-kg, coated three-ply paper bags containing a polyethylene liner.

 

Lagerung

Store VINNOL® H 40/60 under dry conditions and at room temperature (below 25 °C). If proper conditions are maintained, the product has a shelf life of at least 12 months from the delivery date if stored in the original, unopened containers. Beyond its recommended shelf life, the product is not necessarily unusable, but the user should perform quality control regarding the properties relevant to the application.
