General purpose adhesives.

Processing 

VINNOL^® H 15/45 M is generally used in dissolved form.

Ketones and esters are preferably used as solvents for VINNOL^® H 15/45 M. Esters have a lower solvation power compared to ketones. While aromatic hydrocarbons can be used to a limited extent in combination with true solvents, alcohols and especially aliphates are non-solvents for VINNOL^® H 15/45 M.

To prepare the solution, it is recommended to first introduce solvents and liquid additives and then add VINNOL® with stirring. The polymer powder should preferably trickle directly into the stirrer spout in order to achieve uniform wetting and rapid dispersion. Depending on the solvent type, concentration and stirring system, a dissolution time of approx. 30 minutes to approx. 4 hours at room temperature is recommended until a clear, particle-free solution is achieved. By heating the mixture to temperatures of up to approx. 50°C, depending on the solvent system, faster and more complete clear solubility can be achieved.

VINNOL^® H 15/45 M can be plasticized with monomeric and polymeric plasticizers such as phthalates, adipates, sebacates, citrates, phosphates, epoxidized compounds 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, ketone resins as well as with some epoxy resin systems. There is also generally good compatibility with alkyd resins that are not supplied in aliphatic solvents, as well as with numerous polyurethane resin systems. Nitrocellulose, polyvinyl acetate and polyvinyl butyral cannot generally be combined with VINNOL^® H 15/45 M. The compatibility of VINNOL^® H 15/45 M with other polymers must be checked on a case-by-case basis.

If pigments or dyes are used, their compatibility with VINNOL^® H 15/45 M must be checked in advance. Some pigments/dyes can produce thixotropic effects and/or negatively influence adhesion. When it comes to zinc pigments, it should be taken into account that they may catalyze decomposition of VC copolymers at elevated temperatures. This also applies to iron oxide pigments.

Despite good inherent stability, for some applications it is necessary to stabilize coatings based on VINNOL^® H 15/45 M against heat and/or UV light. For thermal stabilization, epoxy compounds such as epoxidized soybean oil, liquid epoxy resin or glycidyl ethers are often sufficient for low requirements.

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.

To achieve maximum adhesion, short-term drying at high temperatures (e.g. 150 – 200°C) is usually helpful.
