Progress in development of UV curable powder coatings

Research Progress of Tung Oil/UV Photocomposite Curing Material

“…Subsequently, TO-based waterborne polyurethane with excellent water resistance, thermal properties and mechanical properties was prepared through the reaction with toluene diisocyanate (TDI) and polyester polyol, and dihydroxymethylpropionic acid (DMPA) as chain extender. In conclusion, TO has been widely used in paint and other related fields [53]. Majority of these applications use high-temperature heating and chemical modifications to induce TO to participate in curing, whilst only a select few studies have been conducted on curing with an environmentally-friendly and efficient UV light [54].…”

Interpol review of paint, tape, and glass evidence 2019–2022

“…Another area of interest in coatings technology is the development of UV curable powder coatings. Czachor-Jadaka et al reviewed the advances in UV curable powder coatings and their advantages compared to thermally cured coatings [ 107 ]. A detailed discussion of the literature on the chemical structure of resins is presented in this review, including unsaturated photoinitiators and additives used in the formulation of UV-curable polyester, urethane acrylates, acrylate and methacrylate resins, epoxy, and polyamides.…”

Effect of additions of anticorrosive pigments on the cathodic delamination and wear resistance of an epoxy powder coating

“…Their strong point is that they have no solvents in their compositions, making them eco-friendly materials. This is of great interest due to current restrictions limiting volatile organic compounds (VOCs) in both waterbased and solvent-based products [2]. Some other advantages of these coatings are, for instance, the possibility of recovering 99 % of the powder lost during the coating process and the superior finish that this type of coating [3,4] has.…”
