A novel waterborne strippable temporary protective coating has been prepared to address the problems of equipment installation collision damage and corrosion during the construction process of nuclear power facilities. The application feasibility of the strippable temporary protective coating in the temporary protection of nuclear power facilities has been studied via salt spray tests, artificial aging tests, damp heat tests and flexibility tests. The results show that the self-prepared strippable temporary protective coating has good salt spray resistance and weather resistance. After 500 hours of salt spray test and 600 hours of artificial aging test, the mechanical properties of the coating have not changed significantly. The toxic and harmful elements are below the limit, which will not induce stress corrosion of the protected equipment. It has good flexibility, elongation, tensile strength, impact resistance and peel strength, which can form a good protective effect on the surface of equipment and is easy to peel off. It is feasible to apply it in the temporary protection of equipment during the construction process of nuclear power facilities. [ABSTRACT FROM AUTHOR]
