10" x 12" HD R3 3 Mil. Photoresist Film 10 Sheet Pack

R3 & R5 photoresist films are engineered for professional sandcarving applications in which quick processing and high production are critical. They promote efficient mask production by eliminating the application of adhesive. They have an adhesive that does not activate until the films are washed out and are repositionable until firmly applied to a substrate. They allow fine-line resolution and allow deeper carving. Remove R3 & R5 with water, or by peeling it off the substrate.
