PRODUCT DESCRIPTION:
Flex 90 is a urethane casting compound that is specifically
formulated for high abrasion and impact resistance. It is recommended for use
for the production casting of highly wear-resistance parts and linings. This
product is a safe, easy to handle, room temperature mixing and curing system
that does not contain TDI, MDI, MDA, or MOCA. Flex 90 is relatively
insensitive to typical environmental moisture and will make good void free parts
without the problems that some conventional urethane systems exhibit. Because of
this product's exceptional toughness and abrasion resistance, casting made with
Flex 90 are particularly suitable for mineral process and metal forming
industries.

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...
