Insta-Flex+ is a rubber-toughened cyanoacrylate that forms superior shock resistant bonds on non-porous surfaces. Clear rubber toughened can be used in applications where you do not want the adhesive to be seen.
Insta-Flex+ is ideal for the bonding of bulkheads, formers and servo rails to the inside of fiberglass hulls and fuselages. Setup time is 20-40 seconds, which can be accelerated with Insta-Set. It forms superior bonds to soft urethane and vinyl plastics, and works well when bonding R/C car tires.
When a joint has a larger than normal gap, flexible CA's provide superior shock resistant bonds.
