This is a one ounce bottle of Bob Smith Industries INSTA-FLEX+™ Clear Rubber Toughened CA Glue. INSTA-FLEX+™ clear rubber toughened has similar qualities to our black IC-2000™ but can be used in applications where you do not want the adhesive to be seen. The carbon component of IC-2000™ that gives the CA its black color also contributes to its unsurpassed strength. Since INSTA-FLEX+™ has this carbon removed, its strength is a little less than IC-2000™ but still superior to standard CA's. When esthetics are important and a flexible bond is required, INSTA-FLEX+™ is your best choice. It forms superior bonds to soft urethane and vinyl plastics. Both INSTA-FLEX™ and INSTA-FLEX+™ work well when bonding R/C car tires. When a joint has a larger than normal gap, flexible CA's provide superior shock resistant bonds.
