Paintwork materials - designations and compatibility. Material compatibility for coatings for use in temperate areas Silicium lacquer Compatibility with art paints

Paints and varnishes are applied to the surface to be protected, as a rule, in multilayer systems, which may consist of primers, fillers, enamels. for various purposes. At the same time, the paintwork materials included in the system can be heterogeneous not only in the pigment part, but also in the film-forming base, but they must be compatible with each other. ISO 12944-5 defines paint compatibility as the ability of two or more paint materials to be used in a coating system without undesirable effects. The use of materials with incompatible binders and solvents that do not provide the necessary interlayer adhesion or a high-quality uniform layer-by-layer coating leads to the need to remove a poor-quality coating and repeat the preparatory and painting work.

When formulating coating systems, it is best to use materials with one type of binder. This is especially true for chemical curing materials (epoxy and polyurethane). To ensure the necessary interlayer adhesion when applying these materials on them, it is necessary to follow the recommendations for the intercoat drying time very accurately. Epoxies and polyurethanes contain very active solvents (xylene, acetone, cyclohexanone), so these materials cannot be applied over reversible physical curing coatings (chlorinated rubber, vinyl, copolymer-vinyl chloride, nitrocellulose, etc.), because dissolution of reversible coatings and formation of defects can occur. When applying epoxy or polyurethane coatings to materials that cure with oxygen in the air (alkyd, oil), swelling and sub-dissolution of these coatings and delamination of the entire coating from the metal can occur.

Polyurethane top coats can only be applied over polyurethane, polyvinyl butyral or epoxy primers and top coats, subject to intercoat drying conditions to ensure intercoat adhesion. Epoxy enamels can only be applied over epoxy, polyvinyl butyral, zinc silicate and ethyl silicate primers and enamels.

Silicone and silicate paints and varnishes are not recommended to be applied over any other types of paints and varnishes, because. most of them are heat curing materials.

Alkyd and oil enamels can be applied on almost all physical curing paints and varnishes, except for bitumen and pitch. When using alkyd and oil enamels on coatings containing bitumen and pitch, the latter can migrate to the upper layers and change their color.

Vinyl, copolymer-vinyl chloride and chlorinated rubber materials can be applied over polyvinyl butyral, acrylic, epoxy ester, zinc silicate and epoxy materials.

When choosing paints and varnishes for repairing coatings after operation, it is first necessary to clarify the paints and varnishes used in the previous painting.

When repairing, it is better to use the same paints and varnishes as in the previous painting or similar ones (on the same binder).

To eliminate errors, it is best to use the experimentally verified recommendations given in technological instructions or other documents related to this material.

Generalized experimental data on the compatibility of coatings on various film-forming bases are presented in Table. one.

Notes:

“-” - can not be applied

“number” - can be applied with the following restrictions:

1. In case the epoxy ester film former is diluted

white spirit;

2. If bitumen and pitch do not penetrate (do not migrate) to the surface

3. When applying anti-fouling enamel, it is advisable to use

intermediate layer to prevent the diffusion of toxins into the bituminous

(pitch) underlying layers;

4. After adhesion test due to the variety of incoming solvents;

5. After roughening the coating or tack;

6. After operation for at least 3 months.

When selecting shop primers, consideration should be given to their compatibility with subsequent coating systems. For right choice table should be followed. 2. (recommendations of ISO 12944-5).

Reviews of site visitors:

Acrylic materials were not often encountered.

First of all, these were acrylic varnishes, which were positioned as varnishes, which, unlike polyurethanes, do not turn yellow over time. Basically, it turned out that way. But there were downsides acrylic materials they cost more and dried longer, which is critical when the deadlines for painting are short and the heating of the painting area is poor. And if the varnish has not dried properly, then there are problems with its polishing, the varnish begins to roll.

Secondly, I had to work with acrylic paints, when there were problems with metallic paint, which was made on the basis water paint. The paint supplier offered to make a metallic based on acrylic paint and, as time has shown, it was the right choice.

There is a misconception about what is acrylic facades. acrylic facades called furniture facades, which are covered with acrylic plastic, plastic and paint are different things. So, do not get confused about what acrylic facades are.
