UV paint for steel pipe

UV paint for steel pipe

UV paint is the abbreviation of Ultraviolet Curing Paint, UV-curable paint, also called photoinitiated coating, light-curable coatings. Named to the film-forming material with PU, PE, NC paint different the UV lacquer paint curing named. Automatically by machinery and equipment roller coating, curtain coating to the surface of the plate of furniture, prompted initiator decomposition under the irradiation of UV light (wavelength 320-390nm) to produce free radicals caused by the resin reaction, instant film curing.
Another interpretation of the UV-curable coatings (ultraviolet curing coating) referred to UV lacquer, PU, PE, NC lacquer film forming materials named in different ways, UV lacquer paint curing named, it is a UV rapidly within a few seconds (ultraviolet, UV) irradiation curing the coating of the film formation.
UV paint is used widely lacquer furniture, main features: After strong ultraviolet light curing, color stability, lasting for years, effectively resolve the door fade and color difference; door mirror flat screen is better, and the film full no orange peel; paint door, one of the more environmentally friendly world health; door other paint door hardness, scratch plan, acid, not easily deformed.
UV paint quality timber information
UV paint curing speed, ultraviolet radiation, within a fraction of a second to reach the surface is dry. When the coating film by a wet film becomes dry film, the shrinkage rate is large, the internal stress is relatively large, and thus poor adhesion between coats. UV paint hardness generally stronger than other paints, usually coating the harder, more brittle, less wear-resistant coating is also easy to crack. When the hardness of the coating exceeds demand, with the change of the thermal expansion and contraction of the floor or the shrinkage of the swelling, changes in the surface coating due to the lack of flexibility can not trace over the floor deformation and deformation, and cracks. Therefore, in finishing when necessary to strictly control the quality of the paint, so as to safeguard the overall quality of the wood.
