PRODUCT DESCRIPTION:
RD 80 FR produces a very high impact rigid 80 Shore D material that is commonly used to make large computer housings, models of
all kinds, and artwork components. It provides a shorter working time which is 5 minutes, verses 15 minutes for RD 81 FR, and 30
minutes for RD 82 FR. The three systems produce the same physical properties after curing.
