RD-407™ is the highest quality casting latex available for mask making, prop making, and slush molded prosthetics. Formulated specifically for casting into gypsum molds, 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 molds. It features a quick skin build-up, excellent detail reproduction and a fast demold. 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™ formulation originally sold by R&D Latex Company in Commerce, California: a recipe that is now well over 50 years old!
