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.
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.
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.
All the information provided is in accordance with the present state of our knowledge. Nonetheless, we disclaim any warranty or liability whatsoever and reserve the right, at any time, to effect technical alterations. The information provided, as well as the product's fitness for an intended application, should be checked by the buyer in preliminary trials. Contractual terms and conditions always take precedence. This disclaimer of warranty and liability also applies particularly in foreign countries with respect to third parties' rights.
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
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 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.
The product can be used for applications with food contact in compliance with FDA 21 CFR §175.105 and §175.300.
Comprehensive information regarding evaluation with respect to other food contact regulations may be requested from our account managers and Wacker subsidiaries.
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.
VINNOL® H 40/60 is packed in 25-kg, coated three-ply paper bags containing a polyethylene liner.
Store VINNOL® H 40/60 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.
