Pigment pastes

Home » Solid surface » Pigment pastes

The use of non-solid pigment pastes is essential if we want to produce a high quality composite or solid surface. To obtain a properly pigmented homogeneous mass we will use pigmented pastes that facilitate the integration of the pigments in the formulation. These are dispersions of high concentrations of solid pigment in resins compatible with the final product to be manufactured. In comparison with the solid pigments, the pigment pastes get a much higher integration of pigments in the mass. They increase their performance considerably. Pigment pastes are responsible for providing the final color to the solid surface piece or other kind of composites. Therefore, it is a component of the solid surface formulation that has a purely aesthetic value. However, as part of the formulation may also affect other aspects such as catalysis, reactivity or viscosity of the mixture.

Choice of pigment pastes suitable for our project

When choosing the most appropriate pigment paste for our project, we will have to consider the following:

pigment concentration of them. they should have at least a 70 of pigment.
performance and coloring strength
vehicle used for pigment dispersion
presence of additives that could damage the reaction or have harmful effects in the catalysis
possible presence of substances to economize and potential harmful causes that may have on our mixture. Basically, we should look for pigment pastes styrene-free.

Due to the increase of the prices of titanium there is a clear tendency to replace this mineral from the pigment pastes. It is necessary to check this point because some pigmest pastes producers are substituting titanium for other cheaper minerals that have effects on the reactivity of the mixture.

Conclusion

In comparison with solid pigments, pigment pastes achieve a much higher integration of the pigments in the mass. They increase their performance considerably. It is necessary to analyse the composition of the pigment pastes in a thorough way. They can incorporate components that could have harmful effects on our mixture.

If you want to know everything related to the solid surface manufacturing, we recommend you to read our extensive article dedicated to this topic. We have developed a pigment paste with high concentrations of pigments specially designed for the production of solid surface products. Availability of pigments based on RAL chart. By individual laboratory tests, we will advise you on the most suitable pigment to your product. If you have any specific needs in this field, do not hesitate to contact us.
