The Monster Makers RD-407 mask latex is the highest quality casting latex in existence for mask making, prop making, and slush molded prosthetics. Popular among many of the most respected special effects artists in the business, RD-407 is a single component, air drying natural latex compound that can be brushed or poured into gypsum molds. It’s perfect for quick skin buildup, features excellent detail reproduction, and has a super fast demold. The Monster Makers RD-407 latex can be painted with adhesive based paints or The Monster Makers latex mask paints. Yielding both a stretchy and durable rubber upon curing, RD-407 comes as a naturally viscous material. Other companies sell what they call RD-407, but this is the original formulation originally manufactured and distributed by R&D Latex Company in Commerce, CA.
