“…Obtained DLP PUA with ZnO additives provide stable and durable protective solutions for both indoor [ 79 ] and outdoor [ 80 ] conditions. However, the chemical durability under different corrosive conditions typical for chemical transportation and storage tanks, household chemical containers, and many other exposed compartments should be studied in detail.…”

The widespread use of epoxy resin (ER) in industry, owing to its excellent properties, aligns with the global shift toward greener resources and energy-efficient solutions, where utilizing metal oxides in 3D printed polymer parts can offer extended functionalities across various industries. ZnO concentrations in polyurethane acrylate composites impacted adhesion and thickness of DLP samples, with 1 wt.% achieving a thickness of 3.99 ± 0.16 mm, closest to the target thickness of 4 mm, while 0.5 wt.% ZnO samples exhibited the lowest deviation in average thickness (±0.03 mm). Tensile stress in digital light processed (DLP) composites with ZnO remained consistent, ranging from 23.29 MPa (1 wt.%) to 25.93 MPa (0.5 wt.%), with an increase in ZnO concentration causing a reduction in tensile stress to 24.04 MPa and a decrease in the elastic modulus to 2001 MPa at 2 wt.% ZnO. The produced DLP samples, with their good corrosion resistance in alkaline environments, are well-suited for applications as protective coatings on tank walls. Customized DLP techniques can enable their effective use as structural or functional elements, such as in Portland cement concrete walls, floors and ceilings for enhanced durability and performance.

This work aimed to enhance the adhesion of photocurable acrylate epoxy/SiO2 nanocomposite coating by adding a crosslinking agent polyisocyanate Desmodur N75 (N75) to make a 2K/UV dual-curable paint formulation. The obtained results showed that the presence of the curing agent N75 slightly reduced the conversion efficiency of acrylate groups during the UV curing process. The analysis of mechanical properties indicated that the coating achieved the optimal mechanical properties at the N75 content of 5 wt.%. The gel fraction, swelling degree, adhesion to wood and steel, relative hardness, impact resistance, and abrasion resistance reached 97.22 %, 310.05 %, 0.1, 0.94, 90 Kg.cm, and 178 L/mil, respectively. FESEM analysis showed that the paint film was fairly homogeneous and tightly structured. The reactions of components of BGDM, HDDA, I184, N75 and nano-SiO2 in the 2K/UV dual-curable acrylate epoxy/SiO2 nanocomposite coatings were described.
