VINNOL® E 22/48 A

VINNOL® E 22/48 A is a hydroxyl-containing copolymer of approx. 75 wt.% vinyl chloride (VC) and approx. 25 wt.% carbon acid esters.

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



特性

VINNOL® E 22/48 A is a thermoplastic, physically drying binder that forms a film when the solvent contained in the formulation has evaporated.

Like all VC copolymers, VINNOL® E 22/48 A 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® E 22/48 A contains approx. 1.8 wt. % free hydroxyl groups and can therefore 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.

Typical applications for VINNOL® E 22/48 A:

  • Magnetic tape coatings
  • Primers
  • Intermediate coatings
  • Two-pack coating systems
  • Baking finishes
  • Adhesives
  • Printing inks

 

Processing 

VINNOL® E 22/48 A is generally used in dissolved form.

Ketones and esters are the solvents most commonly used for VINNOL® E 22/48 A. Ketones, in particular, are excellent solvents for VINNOL® surface coating resins. In the case of VINNOL® E 22/48 A, esters, too, may be used as single solvents. Of the chlorinated hydrocarbons, methylene chloride and 1,2-dichloroethane are true solvents, while tri- and tetrachloroethene have only a swelling effect. Alcohols and aliphatic hydrocarbons do not dissolve VINNOL® E 22/48 A. Aromatic hydrocarbons may be combined to a limited extent with true solvents.

VINNOL® E 22/48 A can be plasticized with monomeric and polymeric plasticizers such as phthalates, adipates, sebacates, citrates, phosphates, epoxides and chlorinated paraffins.

VINNOL® E 22/48 A is fully compatible with all other VINNOL® surface coating resins. It also combines well with a large number of acrylic polymers and ketone resins, plus epoxides, polyurethane and alkyd resins. Polyvinyl acetates and polyvinyl butyrals are in general incompatible with VINNOL® E 22/48 A, while ester-soluble nitrocellulose is compatible to a certain degree. We recommend always checking 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 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® E 22/48 A 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 preparation of the solution and during subsequent storage of the product. VINNOL® -based surface coating compounds should be stored in coated containers.


 

If the product is used in applications other than those mentioned, the choice, processing and use of the product is the sole responsibility of the purchaser. All legal and other regulations must be complied with.

包装

VINNOL® E 22/48 A is packed in 25-kg, coated three-ply paper bags containing a polyethylene liner.

储存

Store VINNOL® E 22/48 A under dry conditions and at room temperature (below 25 °C). Under these conditions, the product has a shelf life of at least 12 months, from the delivery date. If the material is kept beyond the recommended shelf life, it is not necessarily unusable, but the user should perform a quality control on the properties relevant to the application.

The properties determined in our pre-release quality control may change during storage, depending on storage conditions, and deviate from the specification.
