SF100 20G (3M)

The SF100 20G is a Scotch-Weld™ very fast curing medium viscosity modified Ethyl Cyanoacrylate Adhesive suitable for the bonding of a very wide range of materials, including acidic surfaces and some porous ones, where rapid bonding times are required. It is especially formulated for the bonding of plastics, rubbers, paper, leather, metals and other common substrates. SF100 relies less on surface moisture for cure speed than standard cyanoacrylates. Although SF100 has a degree of gap filling ability, it is generally recommended for use on close-fitting parts and fairly smooth, even surfaces. The speed of cure of cyanoacrylates varies according to the substrate to be bonded. Acidic surfaces such as paper and leather will have longer cure times than most plastics and rubber.
