RD 80 FR
PRODUCT HIGHLIGHTS:
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.

| Cure Schedule |
For ultimate heat distortion the material should be post
cured at 1600F(710C) for 6 hours. This gives a HDT
of 1500F(680C) |
this is text meant just to take up lots of space at the bottom of the page, so that if
there is only a table or something in the content part of this page, the content still
takes up the majority of the screen. if there is not any text here, then sometimes there
will be just a table here, and the left navigation bar to the left will be kinda wide...
