Abstract
A polymerizable fluid for sealing and locking engineering parts contains components which allow 2 mechanisms of polymerization, the first of the mechanisms being initiatable by radiation such as ultraviolet light, and an opacifier such as a powder dispersed in the fluid, the opacifier rendering the fluid opaque to the radiation. A coating of the fluid is applied to one of the engineering parts and the coating is exposed to the radiation which initiates the first of said polymerization mechanisms, so that polymerization occurs only in a surface layer of the coating to form a dry tack free crust thereon. Due to the presence of the opacifier, the radiation is obstructed from passing beyond the surface layer and the subcutaneous fluid is unaffected by the radiation. The second polymerization mechanism, suitably a free radical addition polymerization of known type, is initiatable when two engineering parts are assembled together.
