OPEN Acrylics Index

GOLDEN OPEN Acrylics are a slow-drying formulation with a slightly softer consistency than GOLDEN Heavy Body paints. The increased working time of these colors expands their range to include more traditional techniques once only possible with oils.

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.

OPEN Acrylics resist skinning on the palette during long painting sessions and when painting outdoors. Thin applications of paint tack-up, allowing additional layers to be applied and blended. Thicker applications may be worked for hours, however paint over 1/16" thick will dry EXTREMELY slowly. See a video for a demonstration of OPEN Acrylic's drying time.

Blend OPEN with regular GOLDEN Acrylics and Gel Mediums for any application where faster drying is desirable. The drying time of OPEN Acrylics decreases when painting over absorbent surfaces and increases over sealed and non-porous surfaces. See a video demonstration of OPEN Acrylics on sealed and unsealed surfaces.

Unique, relaxed working properties
GOLDEN OPEN Acrylics have a remarkably relaxed working property that facilitates blending, softening, shading, glazing and fine detail. The unique characteristics of OPEN Acrylics allow them to be used with natural fiber brushes and for a range of techniques including portraiture, plein air painting, monoprinting , and screenprinting.

4 mediums & 1 additive for ultimate control OPEN MEDIUMS
OPEN Mediums and Thinner help maximize working time of OPEN Acrylics. OPEN Acrylic Gel (Gloss or Matte) can be used to adjust color strength and translucency while maintaining consistency. OPEN Acrylic Medium (Gloss or Matte) will lower paint viscosity for a more fluid mixture and increased flow. OPEN Thinner helps maintain and adjust the workability of colors on the palette without the use of water mist and moisturizing palettes, unlike mediums and gels OPEN Thinner contains no binding agents.

Compatible with GOLDEN products.
OPEN Acrylic colors, Gel and Medium may be blended with regular GOLDEN Acrylics and Gel Mediums to alter opacity or consistency, while shortening drying and working time. Conversely, the working and drying time of regular acrylic colors can be extended by mixing OPEN Acrylics. The rate of drying and curing will be proportionate to the mixture of fast drying regular and slow drying OPEN products.

Because of the difference in drying times it is not recommended to apply fast-drying products over wet layers of OPEN Acrylics as this can create film irregularities.
