RD-407 Mask Making Latex® is the highest quality casting latex available for mask making, prop making, and slush moulded prosthetics. Formulated specifically for casting into gypsum moulds, RD-407 Mask Making Latex is a single component, air drying natural latex compound used widely by mask makers around the globe. Popular among many special effects artists, RD-407 can be brushed or poured into gypsum moulds. It features a quick skin build-up, excellent detail reproduction and a fast demould. RD-407 can be painted with adhesive based paints or Monster Makers Mask Paints. RD-407 comes as a naturally viscous material that yields a stretchy but durable rubber upon curing. While other companies sell products that they call RD-407, this is the official trademarked RD-407 Mask Making Latex® formulation originally sold by R&D Latex Company in Commerce, California: a recipe that is now well over 50 years old!
