Bob Smith Industries INSTA-CURE+ Gap Filling Medium is a versatile cyanoacrylate adhesive designed for applications where a stronger, more controlled bond is required. Its medium viscosity allows it to bridge small gaps while still flowing smoothly into joints, making it ideal for precision work. INSTA-CURE+ bonds quickly to a wide range of materials including plastic, resin, metal, wood, rubber, and ceramics. It provides a balance between working time and fast cure, giving builders enough time to position parts accurately before setting. A favorite among scale modelers, hobbyists, and professionals, this adhesive is well suited for seam work, reinforcing joints, attaching photo-etch, and general assembly where thin CA would run too easily.
