When applied in a thin layer, it dries in 2 days, but up to 14 days with thicker layers. It dries from the inside not from the surface, hence it is used as an additive to varnishes and oily paints. It causes the entire paint layer to dry evenly, making it flexible and preventing cracking. It has an unpleasant odor and can cause skin irritation. Used in large quantities, it causes the paint layer to darken.
