Liquitex 塑膠彩延乾凝膠 237毫升Liquitex Slow-Dri Gel Additive 237mL

Slow drying time by 40%, without affecting color opacity, so you can work it for longer.
As this is an additive – with no acrylic binders - do not add more than 25% to your color/medium and do not mix with other additives. This can cause the acrylic film to break down, leaving it sticky and prone to shrinkage
