Viscosity and Consistency:
GOLDEN Heavy Body Acrylics are noted for their exceptionally smooth, rich, buttery consistency. These paints have the ability to “stand up” and retain brush strokes or palette knife marks on the canvas.
All HB colors are thixotropic in nature. This means that when brushing or stirring, the paints actually lose viscosity and feel much thinner. The faster the paints are moving, the thinner they feel. Returned to a state of rest, the paints gradually increase in thickness until they are again restored to their formulated viscosity.
The HB colors retain excellent flexibility when dry, greatly diminishing the possibility of cracking that occurs in other natural and synthetic polymer systems. The acrylics can absorb the constant stress and strain placed on canvas when shipped or as it expands and contracts with changes in temperature and humidity. Pl
Product Mixing Abilities:
The HB Colors can be mixed with all of our GOLDEN Mediums, Gels and other paint lines, including our Airbrush Colors, Fluid Acrylics, High Load Colors, Iridescent Colors, Paste Paints, and Matte Acrylics. By mixing paint lines, artists can produce a wide range of paint consistencies without compromising color strength. Heavy Body viscosity can also be reduced successfully with water. Remember: the more water added to the acrylics, the greater the subsequent shrinking of the paint layer. Too much water will reduce the binding capability of acrylic paints and tends to flatten out their sheen. Water works most effectively to increase the fluidity of the HB paints if a small amount of Acrylic Flow Release is added to the mixture.
Blending with Mediums:
The GOLDEN fluid mediums, including Polymer Medium, Acrylic Glazing Liquid, the GAC Mediums and the Airbrush Mediums, can be used to thin Heavy Body Acrylics. They also add a myriad of unique possibilities to the working and gloss properties of the paint surface. All GOLDEN mediums retain the film integrity of the acrylic, and in some cases they actually enhance the durability of the paint film. (Refer to Gels & Mediums Product Review for more information).
Product Gloss Variations:
When producing the HB line, GOLDEN consciously broke the mold of the acrylics made in the past. Most acrylics were produced to have an even satin sheen across the range of colors. Manufacturers felt artists wanted this even sheen to avoid the differences encountered by oils. In oils, the colors requiring very little oil (lean colors) tended to be very matte, while those colors requiring substantial amounts of oil (fatty colors) tended to be quite glossy.
