Instacoll Base Yellow 100m. Our acryl-based Instacoll glues allow you to work on your gilding project in your own time. Requiring only 30 to 45 minutes drying time, you can restore their adhesiveness, for up to several months following application, by using our Activator
solution. Yellow Istacoll provides you with a base color which minimizes the visibility of micro-tears and holes in the gold-leaf.
