Can-Printing Process Uses UV-Curable Coating

چکیده
Approximately 100 billion aluminum cans are produced annually, mainly for the beverage industry. Early technologies for decorating the cans often used solvent-based coatings containing solvents at concentrations of -70% to 75% by volume (Randall 1992). The solvent composition was typically a mixture of aliphatic hydrocarbons, aromatics, ethers, cellosolves, and acetates. Unfortunately, this method released significant emissions of volatile organic compounds (VOCs) and hazardous air pollutants (HAPS) into the environment.

UV-Curable Coating Process on CMYK-Printed Duplex Paperboard, Part II: Effects of Nano-TiO2 Modification
The influence of TiO2 nano-particles (nano-TiO2) was studied relative to the mechanical and optical properties of CMYK printed paperboard after coating with a UV-curable varnish. Commercial duplex paperboard (glazed grayback paperboard, 230 g/m) was printed with a CMYK offset printing process. Board samples were coated with a nano-TiO2 modified UV-curable varnish at four treatment levels (0, 0....

The formulations contained different acrylate monomer with different structure and functionalities and TiO2, were applied to obtain pigmented acrylic films by UV exposure. The conversion and mechanical characteristic were correlated. The results showed that there is a significant interaction between pigment, reactive diluents’ type and mechanical properties of coatings. It seems that cured film...
متن کاملWater-soluble UV curable urethane methyl acrylate coating: preparation and properties.
Two kinds of water-soluble and ultraviolet (UV) curable oligomers were synthesized and characterized. The oligomers were evaluated as resins for water-based UV curable coating. The rheology of the two oligomers' aqueous solutions was investigated in terms of solid fraction, pH dependence, and temperature dependence. The solutions were found to be Newtonian fluid showing rather low viscosity eve...
