VINNOL® H 40/43

• VINNOL® H 40/43 is a vinyl acetate-rich VC 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 40/43 as an additive in solvent-free 100% systems to improve adhesion and pigment wetting or to reduce shrinking.
• VINNOL® H 40/43 also shows a surprisingly good compatibility with ester soluble nitrocellulose resins and can be used for their modification.

Processing

• VINNOL® H 40/43 is generally used in dissolved form.
• Ketones, in particular, are excellent solvents for VINNOL® surface coating resins. In the case of VINNOL® H 40/43, esters, too, may be used as single solvents. Of the chlorinated hydrocarbons, methylene chloride and 1,2-dichloroethane are true solvents. Aromatic hydrocarbons have a swelling effect but may be combined to a limited extent with true solvents up to 80%. Alcohols and aliphatic hydrocarbons do not dissolve VINNOL® H 40/43.
• VINNOL® H 40/43 is also soluble in various monomers (e.g. styrene, methyl methacrylate, 2-ethylhexyl acrylate, 1,6-hexanediol diacrylate and others).
• VINNOL® H 40/43 can be plasticized with monomeric and polymeric plasticizers, such as phthalates, adipates, sebacates, citrates, phosphates, epoxides and chlorinated paraffins.
• VINNOL® H 40/43 is fully compatible with all other VINNOL® surface coating resins. It also combines well with many acrylic polymers and ketone resins, ester soluble nitrocellulose as well as with some epoxides. Alkyd resins, polyvinyl acetates and polyvinyl butyrals are in general incompatible with VINNOL® H 40/43. We recommend always checking the compatibility of VINNOL® H 40/43 with the polymer in question.
• VINNOL® H 40/43 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 40/43 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 resins should be stored in coated containers.

• VINNOL® H 40/43 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 40/43 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.

VINNOL® H 40/43 is packed in 25 kg, coated three-ply paper bags containing a polyethylene liner.

Store VINNOL® H 40/43 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.
