VINNOL® H 15/45 M
VINNOL® H 15/45 M is a carboxylate-containing terpolymer of approx. 84 wt. % vinyl chloride (VC), approx. 15 wt. % vinyl acetate (VAc) and approx. 1 wt. % dicarboxylic acid.
Its main use is as a binder for surface coating compounds and printing inks.
特性
VINNOL® H 15/45 M 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 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
By virtue of its carboxyl content, VINNOL® H 15/45 M adheres excellently to metal surfaces. It can 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.
数据表
Typical applications for VINNOL® H 15/45 M:
- Heat-sealable lacquers
- Metal paints
- Paper and film coatings
- Printing inks
- Primers
- Masonry paints
Processing
VINNOL® H 15/45 M is generally used in dissolved form.
Ketones and esters are the solvents most commonly used for VINNOL® H 15/45 M, 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. Aromatic hydrocarbons may be combined to a limited extent with true solvents.
VINNOL® H 15/45 M can be plasticized with monomeric and polymeric plasticizers such as phthalates, adipates, sebacates, citrates, phosphates, epoxides, and chlorinated paraffins.
VINNOL® H 15/45 M 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. We recommend always checking the compatibility of VINNOL® H 15/45 M with the polymer in question.
The compatibility of VINNOL® H 15/45 M 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 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.
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.
包装
VINNOL® H 15/45 M is packed in 25-kg, coated three-ply paper bags containing a polyethylene liner.
储存
Store VINNOL® H 15/45 M 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.
