Nevertheless, a solitary LED curing coating struggles to fulfill the requirements in terms of curing depth, curing chroma, and comprehensive performance. Based on these, four types of polyurethane acrylate (PUA) coatings were fabricated through two-step synthesis and LED/moisture dual curing technology using cycloaliphatic isocyanate (IPDI), aliphatic isocyanate (HDI), monofunctional acrylate (HEMA), and trifunctional acrylate (PETA) as the primary raw materials. The dual curing system integrates the advantages of LED curing and moisture curing, and mitigates the shortcomings of incomplete curing and poor comprehensive performance of single LED. The experimental results show that these four dual-curing coatings show a certain degree of optimization in comprehensive properties such as curing properties, thermal properties, mechanical properties, and coating properties. In particular, the dual-curing coating prepared with HDI as the hard segment and PETA as the end-capping agent has a surface drying time of only 5 s. After dual curing, the gel content, water contact angle, tensile strength, shear strength, hardness, and adhesive force of the sample can respectively reach 97.8 %, 112.4°, 17.26 MPa, 3.7 MPa, 58.5 Shore D, and 5 B.

It is also notable that the curing depth of the dual-cured coating can reach 8.96 mm, which is significantly higher than the 3.76 mm of the single light curing, and the colored curing is complete.

Future high-performance green buildings will require building envelope coatings with multiple functions, such as RC, self-cleaning, and thermal insulation. However, the existing RC coatings for buildings usually have only a single function or two of them. Hollow ceramic microbeads-SiO₂/polydimethylsiloxane (HCMs/PDMS) hybrid coatings were proposed to address the shortcomings of the RC coatings. The solar reflectance and infrared emissivity of the HCMs/PDMS coating were 92.4 % and 93.0 %, respectively. Under direct sunlight, the HCMs/PDMS coating achieved subambient RC effects of 11.1 °C and 4.81 °C in summer and winter, respectively. In addition, the HCMs/PDMS RC coating surface has a self-cleaning function (contact angle of 156° and a rolling angle of 7.2°), which improves the ability of the coating surface to prevent dust accumulation and thus improves the durability of the coating's RC performance. In particular, the HCMs/PDMS coating exhibits stronger adhesion to the building substrate than existing hollow glass microbeads (HGM) based coatings. Moreover, the HCMs/PDMS coating has an extremely low thermal conductivity (0.13 W·m⁻¹·K⁻¹), which blocks the diffusion of heat from the hot outdoors to the cool indoors in the summer and from the warm indoors to the cold outdoors in the winter and contributes to the reduction of a building's total year-round energy consumption by further restricting the heat exchanges between indoors and outdoors. The results of building energy simulations demonstrated that the use of HCMs/PDMS coatings in typical large cities around the world resulted in year-round building energy efficiency of more than 8 % in more than 66 % of the 18 typical cities.
