Abstract

Purpose - To develop a water repellent (WR), rodent repellent (RR) and UV resistant (UVR) formulation for woven nylon tapes to be used in aircraft arrester system. Design/methodology/approach - UVR, WR and RR formulation for woven nylon tapes were prepared using silicone oil as WR, oleoresin (OR) (red chilly extract) and denatonium benzoate (DB) as RRs, carbon black for UV resistance and butyral resin as binder. Findings - Incorporation of silicon oil improved the water repellency of the processed nylon tapes. DB and OR in the formulation protected the tapes from rats. The former showed excellent protection for nylon tapes in the experimental conditions. More than 150 days of protection has been achieved in comparison to 27 days using OR. The presence of carbon black along with silicon oil and DB in the formulation enabled the nylon tapes UVR-WR-RR in a single processing step. The presence of RRs and WRs within the same formulation did not affect each other's performance. Research limitations/implications - OR and DB were used as RR materials and silicone oil as WR material. In addition, some other RR and WR materials could have been evaluated. Practical implications - The formulation imparts UV resistance, water and rodent repellency to the nylon tapes after processing. Originality/value - This type of formulation is novel for processing of nylon tapes to be used in aircraft arrester systems.
