Radiation rapid cure processing

As a preparative technique, the present radiation grafting process is useful for polypropylene and cellulose, however with leather care is needed, since the solvents tend to dry out this trunk polymer and embrittle it with time. Thus for many leather treatments, the radiation rapid cure processes mentioned at the end of this paper are to be preferred. 

Comparison of Grafting with Radiation Rapid Cure Processing for Upgrading Materials... 

The effect of sensitiser structure on UV grafting of monomers to polypropylene and cellulose is examined. The use of the radiation grafting technique is compared with radiation rapid cure polymerisation as processes of use in the field of renewable resources. 

Cationic cured epoxies may also be crosslinked by electron beam radiation. A major application for this technology is the repair of composite aerospace structures. Direct benefits of EB processing include rapid cure, allowing completion of a permanent repair in the same or less time than a traditionally temporary repair, and ease of material handling. Other... 

UV-radiation curing has become a well-accepted technology which has found numerous industrial applications because of its distinct advantages 1-3. One of its main characteristics is the rapidity of the process which transforms quasi-instantly the liquid resin into a solid polymer under intense illumination by a UV-source or a laser beam4. The polymerization rate can be finely controlled by acting on the initiation rate through the intensity of the UV radiation. It is... 

Monomers with low molecular weights will diffuse into the wood more rapidly than polymers such as PEG. In a second phase, their in situ radiation curing will form wood consolidants that are much stronger than PEG. However, this method requires very heavy irradiation equipment, which is usually available only in nuclear research centers. The irradiation cell dimensions and the 7-source geometry limit the size of the artifacts. For mainly these reasons, the radiation process was applied in very few institutions and in most cases only at the experimental level. The Nucleart Laboratory, which routinely conserves waterlogged wood by this technique, is located in the Grenoble Nuclear Research Center of the French Atomic Energy Commission.
