Hi to the MITRA team,
I have questions about the pigment concentration (pigment load) of the Golden Paint line.
There are four viscosities in Golden paints (heavy body, soft, fluid and high flow acrylic) and I would like to know if there are differences in the pigment concentration between the Golden acrylic range.
I understand that the polymer binder used is the key to the consistency of the paint, but strictly speaking about the pigment concentration, what is the most loaded paint?
It is said in the description of the Golden paints that they contain no fillers or extenders, does it mean that the paint is fully pigmented as in some high quality oil paints?
If I want to extend acrylic paint while maintaining the most of the saturation, what should be the optimal dilution factor?
Thanks in advance,
Cyril
Thank you for your replies,
I wasn’t aware of the Golden high Load line, they may be an excellent answer to my need.
Does it mean that it is possible to use them straight as a gesso-like ground? — or a primer like a sizing medium?
Thank you for clarifying the dilution factor, the 1:10 acrylic medium to water is a very good tip indeed.

Hi Cyril
I will forward this to our Golden representative.
Hello Cyril,
the most loaded paints in the Golden paint lines are the High Load custom paints. They were originally developed as colored gesso and have such a high pigment load, that they produce an absorbent surface with a satin/matt sheen. The Heavy Body, Fluid and High Flow Acrylics all have the maximum pigment load for their respective binder. The High Flow Acrylics, being so thin, can carry less pigment than the Fluid or Heavy Body paints, without pigment crashing at the bottom of the container. When comparing acrylics and oils in their capacity to bind pigment, then oils have a greater capacity. In the JP Article https://www.justpaint.org/pigment-volume-concentration-and-its-role-in-color/ you can see that water color has a higher Pigment Volume Concentration (PVC), than oil and oil a higher one than acrylics. When using an acrylic medium, gel or paste for extending your acrylic paints, then there is not maximum or optimal mixing ratio and it would depend entirely on your artistic perception what’s optimal. Matte mediums or gels would create more opaque mixtures due to the matting solids. If diluting with water, a good starting point is a 1:1 mixture and if more dilution is required, we recommend making a blend of 1 part acrylic medium to 10 parts water and using that blend to further dilute your paints to any extend you like.
