2. UV coating - Wikipedia

   en.wikipedia.org/wiki/UV_coating

   Coatings are usually applied to plastic substrates via spray, dip, roll, flow and other processes. UV-curable coatings are often specified for plastic parts because the process does not require heat, which can distort the plastic shape. [9]

3. UV curing - Wikipedia

   en.wikipedia.org/wiki/UV_curing

   UV curing (ultraviolet curing) is the process by which ultraviolet light initiates a photochemical reaction that generates a crosslinked network of polymers through radical polymerization or cationic polymerization. [1] UV curing is adaptable to printing, coating, decorating, stereolithography, and in the assembly of a variety of products and ...

4. Photopolymer - Wikipedia

   en.wikipedia.org/wiki/Photopolymer

   Acrylated urethane oligomers are typically abrasion resistant, tough, and flexible, making ideal coatings for floors, paper, printing plates, and packaging materials. Acrylated polyethers and polyesters result in very hard solvent resistant films, however, polyethers are prone to UV degradation and therefore are rarely used in UV curable material.

5. Photo-oxidation of polymers - Wikipedia

   en.wikipedia.org/wiki/Photo-oxidation_of_polymers

   Different UV stabilizers are utilized depending upon the substrate, intended functional life, and sensitivity to UV degradation. UV stabilizers, such as benzophenones, work by absorbing the UV radiation and preventing the formation of free radicals. Depending upon substitution, the UV absorption spectrum is changed to match the application ...

6. Hindered amine light stabilizers - Wikipedia

   en.wikipedia.org/wiki/Hindered_amine_light...

   Hindered amine light stabilizers (HALS) are chemical compounds containing an amine functional group that are used as stabilizers in plastics and polymers. [1] These compounds are typically derivatives of tetramethylpiperidine and are primarily used to protect the polymers from the effects of photo-oxidation; as opposed to other forms of polymer degradation such as ozonolysis.
