Flex 40 provides users with an extremely tough flexible urethane rubber excellent for duplicating/casting soft rubber parts or for making soft urethane rubber molds. It is extremely easy to use. The easy to use system does require vacuum or pressure to achieve perfectly bubble free castings. However, users can achieve very minimal air entrapment by simply mixing the A & B side together extremely slowly for 2 minutes.

Prior to use, read all Technical Data Sheets/Instructions and Safety Data Sheets linked below.
