For radiation curing

Pentaerythritol and trimethylolpropane acryUc esters are usefiti in solventiess lacquer formulations for radiation curing (qv), providing a cross-linking capabihty for the main film component, which is usually an acryUc ester of urethane, epoxy, or polyester. Some specialty films utilize dipentaerythritol and ditrimethylolpropane (94,95). [Pg.466]

The tensile strength of NR compounds in the presence of cross-link promoters such as dichlorobenzene is increased as compared to the sulfur-accelerator and peroxide-curing systems. The retention of the maximum tensile strength at elevated temperamres is greater for radiation cured than for chemically vulcanized NR [326,327]. Also reported are a higher abrasion resistance [328] and a lower flex life in the case of radiation-cured system. Effect of phenoxy ethyl acrylate (PEA)... [Pg.879]

The retention of the maximum tensile strength at elevated temperatures is greater for radiation cured than for chemically cured natural rubber. The physical properties after high-temperature aging are not improved, however. Lower flex life and higher abrasion resistance of radiation cross-linked NR were reported. Other properties, such as permanent set, hardness, and resilience, were found to be nearly equal. [Pg.108]

Radiation-curable coatings were developed by W. J. Burlant (of the Ford Motor Company) in 1962. Acceptance of finishes designed for radiation curing (high-solids materials formulated to be cured by UV and EB systems) is growing at roughly 8 percent per year with a market size of approximately 85 million lb.

Photochemical initiators are utilized for the production of lithographic plates and for radiation curing coatings and inks but not in the manufacture of plastics. Electrolytic polymerizations find apphcations in the coating of metal sheets by plastics. [Pg.119]

Radiation curing For the application of radiation curing, at least one adherend has to be suitable for UV radiation. It is, furthermore, applicable that the diaphaneity of a material cannot be equated with its transparency for UV-rays. The radiation energy actually available for radiation curing in the glueline can be determined by means of a UV measuring instrument. [Pg.104]

For radiation curing, a sealed tube containing the blend film was placed in the y-ray (60Co source) radiation chamber at the dose rate of 1.32 x 10 R/min. for 30 minutes. [Pg.499]

Over the years, a number of compounds have been identified to photoinitiate cationic polymerization of monomers designed for radiation curing applications generally, and negative-resist applications specifically. The most prominent of these initiators are onium salts. [Pg.273]

After evaporation of the solvent, the coatings are thermally or radiation cured. Radiation cure has been carried out with a medium pressure mercury lamp for 1, 3, 5, 8, 10, 13, 15, and 20 seconds in both the absence and the presence of a photosensitizer. The curing proceeds for several seconds in the absence of a photosensitizer, and very fast in the presence of benzophenone, a common photosensitizer. The two conjugated triple bonds of the linear polymers evidently require very low energy and easily cross-link with standard coatings equipment for radiation cure. The coatings, cured at radiation time longer than 10 seconds, have a pale yellow color. The thermal cure (without radiation) proceeds at 100 C for about 15 minutes. [Pg.202]
