This report discloses the outdoor termite resistance performance of PSL samples treated with zinc borate at a dosage of 0.85% BAE and 1.72% BAE in Wuxi, China. The outdoor field trial lasted for 15 years and observations were made after 6 months, 3 years, 5 years 1 month, 6 years 6 months and 15 years. The retaining rates of B2O3 and ZnO in the final samples were also tested, and the hypothesis was given to explain the key findings.
