Definitions
- the invention relates to a pigment paste for tinting a coating agent, a process for producing the pigment paste and a coating agent containing coating agents and pigment paste.
- the invention further relates to a method for producing a coating composition using the pigment paste and the use of siliconate for stabilizing and / or increasing the storage stability of pigment pastes.
- Pigment pastes for tinting coating agents such as paints and lacquers
- Pigment pastes are generally known. Pigment pastes are usually produced by dispersing pigments and, if appropriate, fillers and other suitable materials and using them with the tinting agent before use
- Coating agent mixed Color mixing systems of this type are superior to conventional coating materials, particularly with regard to storage and logistics.
- Tinted coating agents contain at least one
- Coating agent and at least one pigment paste are tinted
- Coating agents are also referred to as coating agents.
- pigment pastes Compared to adding powdered pigments to a coating agent, pigment pastes have the advantage that they can be distributed easily and homogeneously and are easy to dose. It is also advantageous that they do not contain paint dust, since this easily contaminates the environment when mixed. Finally, pigment pastes can be adjusted to the desired color strength and can therefore be metered in and mixed in in a simple manner via the volume into a coating agent such as, for example, a plastic emulsion paint.
- pigment pastes can be used to tint very different coating agents.
- An important area here is that Tinting plastic emulsion paint, also known as emulsion paint.
- Dispersion paints usually contain relatively large amounts of organic chemical constituents, in particular synthetic resin polymers, in particular in the form of synthetic resin dispersions.
- emulsion paints and / or pigment pastes usually require preservatives, in particular biocides, such as isothiazolinones.
- preservatives in particular biocides, such as isothiazolinones.
- these can cause irritation and skin irritation, especially in allergy sufferers.
- Dispersion paints which do without preservatives have been developed in the past few years in the publications EP 1 297 079 B1,
- DE 1 031 910, DE 10 2014 013 455 Al and DE 10 2016 002 221 Al each describe dispersion paints that do not require preservatives.
- pigment paste containing preservatives is thus introduced into the emulsion paint and the tinted emulsion paint is no longer suitable for use by allergy sufferers.
- pigment pastes vary significantly more in their compositions and concentrations than emulsion paints.
- the Amount of pigment and water can vary in larger ranges than for
- Dispersion paints are common and consequently pigment pastes can also have a greater variance in their viscosity.
- Another particular challenge with pigment pastes compared to emulsion paints is the high flexibility that pigment pastes have to provide.
- the pigment pastes should be able to be mixed flexibly with very different colors, varnishes or plasters. For this, the pigment paste must have good miscibility and compatibility with
- the coating compositions sometimes have significant differences in their composition and pH. Such a degree of miscibility and compatibility of the pigment pastes is therefore difficult to achieve.
- pigment pastes are significantly higher than the storage requirements for emulsion paints.
- Pigment pastes usually have to be stored for significantly longer periods, since they are often used irregularly to tint colors and are not used up relatively quickly like finished colors. There they are exposed to pests from the air in combination with the high humidity in the mixing container.
- Pot preservatives also contain fungicides to prevent infestation in the mixing container.
- Concentrated paste that can be used over long periods of time poses the risk that the pigment paste will not be permanently stable in the form and will be continuously compatible in all required qualities.
- the present invention therefore has as its object a
- preservative-free pigment paste that can be used for tinting a coating agent, in particular in automatic paint mixers, over a period of at least six months without any loss of quality and without pest infestation.
- the present invention also has the task of a
- preservative-free pigment paste that can be used flexibly to tint different coating agents.

- Pigment paste can also be combined with a wide variety of coating agents and easily mixed.
- the pigment paste according to the invention is outstandingly suitable for tinting preservative-free emulsion paints. Preservative-free emulsion paints and other preservative-free coating agents can consequently be tinted with the pigment paste according to the invention.

- the pigment paste contains at least one filler. According to another preferred embodiment, the pigment paste contains no filler.
- the use of fillers in the paste depends on the overall composition of the paste. In principle, the price of the paste can be reduced by using fillers. However, the use of filler can also lead to difficulties in the compatibility of the components in the paste, in particular the filler can settle in the automatic mixer. Additional spores can also be added to the system via fillers. In addition, fillers have negative effects on glossy systems and generally reduce the weathering stability of the coating agent.

- the proportion of the wetting agent in the pigment paste can vary within a wide range and depends in principle on the desired viscosity of the pigment paste.
