A room temperature curing ethyl cyanoacrylate adhesive has been introduced. This high strength bonding compound is a single component system and offers excellent adhesion to glass, ceramics, metals, rubber, and most plastics. The adhesive has a low viscosity of 2,000-2,400 cps and is easy to apply. Bonds range from a few seconds to under a minute depending on atmospheric humidity and the substrates being bonded. The adhesive is also transparent and has a refractive index of 1.48. It has a Shore A hardness of 85; is resistant to most types of environmental exposures including moderate heat, aging, and many chemicals; and is available for use in 1/3 ounce, 1.0 ounce, and 1.0 lb bottles.
