R5 had especially been developed to produce repositionable sandblasting masks. The material does not immediately stick and can be positionized easily and exactly. The adhesive in the special R3/ R5 emulsion will only become active after absorbing humidity.
R5 photoresist films make decorative sandcarving simple, productive and enjoyable. R3 and R5 are engineered for professional sandcarving applications in which quick-processing and high production are critical. R3 and R5 promote efficient mask production by eliminating the time-consuming and messy application of adhesive.
