3M Scotch EC100 Rite-Lok Instant Adhesive Glue3M EC100 Rite-Lok Instant Adhesive Glue is a low-medium viscosity cyanoacrylate adhesive that is fast curing and useful for general purpose bonding. It is a single component, high strength ethyl cyanoacrylate liquid adhesive which is designed to bond to a variety of substances including most plastics, rubbers, metals, and other common substrates. Some tips for applying 3M EC100: Ensure parts are clean, dry, and free from oil and grease. Bond speed is typically very fast so ensure that parts are properly aligned before dispensing. Apply sparingly to one surface and press parts firmly together until handling strength is achieved. As a general rule, as little cyanoacrylate as possible should be used. Over application will result in slower cure speed and lower bond strength.
