Summary: The application of flame retardant coatings is an effective solution to enhance the fire retardancy of wood flooring. This study found that the addition of a phosphorus-based monomer improved the adhesion and fire performance of the coatings without impacting photopolymerisation. However, the flame-retarded coatings displayed higher hygroscopy.

Summary: This study introduces tetraphenylethylene (TPE), which has aggregation-induced emission (AIE) effect, into UV-curable adhesive and optimizes the concentration of TPE-modified methacrylate (TPE-MA) to achieve blue fluorescence under UV light for visualizing the adhesive's location. By comparing the cured products, it is found that the one with TPE-MA forming covalent bonds has higher fluorescence intensity and better stability. The addition of a small amount of TPE-MA has no significant effect on the adhesive's performance.

Summary: In this study, a series of UV-curable, cycloaliphatic polyesters were synthesized and the effect of spiroglycol (SPG) loading level on the properties of the coatings was investigated. The oligomers containing 30% and 45% SPG showed suitable properties for powder coating applications, exhibiting comparable weatherability and corrosion resistance to conventional coatings, along with superior impact resistance and substrate adhesion.

Summary: The hydrophobic properties of UV curable palm oil polyurethane were enhanced by the addition of fluoroacrylate monomer through the formation of a crosslinked complex network. Fourier transform infrared spectroscopy confirmed the successful attachment of the fluoro group to the polyurethane. The fluorinated polyurethane showed improved hydrophobicity, with the highest contact angle and lowest sliding angle observed in FPOPU-6% and FPOPU-2% respectively. The addition of fluoroacrylate also reduced the water absorption properties of the polyurethane.

Summary: A new UV-curable maleimide-terminated polyimide was prepared and characterized, and formulated with a UV-curable polyester resin to prepare a hybrid powder coating system. The addition of polyimide improved the thermal stability of the polyester and increased the deformation resistance of the UV-cured films. The viscoelastic properties of the hybrid system were most improved when 16% weight percent of polyimide was added into the system.

Summary: Three urethane methacrylates were used as reactive diluents in UV-curable polyester powder coatings, with one monofunctional derivative and two di-functional derivatives of different chain lengths. The addition of 10 wt% reactive diluent significantly reduced viscosity by an order of magnitude. The type and concentration of reactive diluent directly influenced the properties of the films after UV-curing, such as glass transition temperature, modulus, % elongation-at-break, and crosslink density. Of the di-functional reactive diluents used, the derivative with a shorter methylene spacer group resulted in more heterogeneous crosslinked networks.

Summary: UV-curable coatings are gaining more attention for their high performance and environmentally friendly advantages, meeting coating development requirements. Vinyl oligomers play a key role in coating performance but face challenges due to high viscosity and low vinyl functionality. By polymerizing acid anhydride and glycidyl methacrylate, polyesters with lateral double bonds were prepared, with epoxy compounds used to adjust resin viscosity and functionality. Characterization of the polyesters' molecular structure and weight showed that specific acid anhydrides and glycidyl ethers significantly affected coating film properties, with specific ratios resulting in low viscosity and high hardness paint films with excellent water and alcohol resistance.

Summary: A series of SiO2 coated TiO2 particles (TiO2@SiO2) were prepared as UV-shielding fillers for UV-curable coatings. The presence of a continuous and dense SiO2 layer on TiO2 surface not only improved the dispersibility of TiO2, but also effectively inhibited the photocatalytic activity of TiO2 without sacrificing its UV-shielding ability, thereby significantly enhancing the anti-aging property of UV-curable coatings. Salt spray test showed that the aged UV-cured coating with TiO2@SiO2 exhibited better corrosion protection behavior than the aged pure resin coating as well as the aged TiO2 coating.
