Mold Max XLS II can be thickened with Thivex additive for brush-on applications. Mold Max XLS II silicone can be used to cast a variety of materials including concrete, wax, gypsum, low melt alloys/metals and urethane, epoxy or polyester resins (without using a release agent).

Although not usually necessary, a release agent will make demolding easier when casting into or over most surfaces. Ease Release¨ 200 is a proven release agent for making molds with silicone rubber and for releasing new silicone from cured silicone.
