An adhesive system comprising, as a primer, an organometallic compound and an organic polymer, which is useful in bonding non-polar or highly crystalline resin substrates together or bonding said resin substrates and another material, such as a solid material, a coating material, paint or printing ink by using a 2-cyanoacrylate adhesive.

Primer composition

A curable composition, in which powder of an organic or inorganic compound is added to and dispersed in a 2-cyanoacrylate and an acidic substance and a basic substance are contained as the stabilizer. In the curable composition of the invention, powder of organic or inorganic compound can be stably dispersed into the composition by the combined use of the acidic substance and the basic substance, thereby providing desired properties with ease while giving excellent storage stability and maintaining the instantaneous curing property of the composition. The curable composition can generally be used as adhesives, coating agents, paints, potting agents, etc.

Curable composition

A primer comprising an organometallic compound and an organic polymer, which is useful in bonding non-polar or highly crystalline resin substrates together or bonding said resin substrates and another material, such as a solid material, a coating material, paint or printing ink by using a 2-cyanoacrylate.

Method of bonding non-polar or highly crystalline resin substrates

Fingerprint developers are made of woven or non-woven fabric of hydrophobic synthetic fibers which is impregnated with a 2-cyanoacrylate. The synthetic resin for the fibers may be polyethylene, polypropylene and the like. This developer is placed in a closed vessel together with an article suspected of containing a latent fingerprint with or without a cup of hot water. Rapid development of fingerprints is possible.
