Processing
- VINNOL® H 15/45 M SPECIAL is generally used in dissolved form.
- Ketones and esters are the solvents most commonly used for VINNOL® H 15/45 M SPECIAL, ketones being more efficient than esters. 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® H 15/45 M SPECIAL. Aromatic hydrocarbons may be combined to a limited extent with true solvents.
- VINNOL® H 15/45 M SPECIAL can be plasticized with monomeric and polymeric plasticizers such as phthalates, adipates, sebacates, citrates, phosphates, epoxides and chlorinated paraffins.
- VINNOL® H 15/45 M SPECIAL 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 15/45 M SPECIAL. We recommend always checking the compatibility of VINNOL® H 15/45 M SPECIAL with the polymer in question.
- The compatibility of VINNOL H 15/45 M SPECIAL 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 15/45 M SPECIAL 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 the 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 15/45 M SPECIAL 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 15/45 M SPECIAL 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.
