Produces a non-glare, low sheen surface that will intensify dull colors. Does not drastically reduce color depth as does Matte Medium. 100% acrylic polymer varnish. Water soluble when wet. Good chemical and water resistance. Dry to a non-tacky, hard, flexible surface that is resistant to retention of dirt. Resist discoloring (non-yellowing, non-fogging) due to humidity, heat and ultraviolet light. Depending upon substrate, allows moisture to pass through (breathable). Permanent Flexible Varnishes will not crack as surface expands and contracts during temperature and humidity changes. Applicable for any surface (flexible and inflexible) suitable for acrylic paint and mediums, such as canvas, paper, wood, Plexiglas, etc. Not for use over oil paint. You may do touch up applications over Permanent Varnishes.
