MID-CURE™ 15 min. epoxy is used where other glues will not bond well. With 15 minutes of working time you don’t have to rush to assemble your project. It is more water resistant and can be used as a substitute for QUIK-CURE™ in most applications. MID-CURE™ is our most flexible epoxy and is ideal for gluing joints that see stress and flex. Allow 45 minutes before handling parts and 2 hours for full strength.
