OPEN Slow-Drying Acrylics

OPEN Slow-Drying Acrylics

OPEN Acrylics are a slow-drying paint with a slightly softer consistency than our Heavy Body paints. The increased working time of these colors expands their range to include more traditional techniques once only possible with oils. Thick applications can dry extremely slowly, so we recommend artists only use OPEN Colors thinly (< 1 mm). Drying time can also be accelerated by mixing OPEN with faster-drying acrylics like our Fluid and Heavy Body colors. The slow-drying capability of OPEN Acrylics also makes the suitable for some printmaking techniques.

Because OPEN Acrylics dry slowly, painters who cover their palettes or use sealed containers have been able to use the same colors for weeks, reducing the amount of paint wasted and preserving color mixtures for future use. 


  • Increased working time for blending, glazing, shading and softening
  • Colors stay wet longer on the palette resulting in less waste
  • Ideal for portraiture, plein air and printmaking
