Itheyiphu ye-PTFE yokushisa okuphezulu inokumelana nesifutho sikasawoti esihle kakhulu, kodwa amaphuzu abuthakathaka ungqimba olunamathelayo kanye nemiphetho ye-fiberglass substrate. Izindlela zokuhlola: Ukuhlolwa kwe-1000h neutral salt spray (NSS), ukulinganisa ukugcinwa kwamandla e-peel (≥80% edingekayo), ukukhubazeka okubukwayo (ukuphakamisa, amabhamuza), kanye nokugqwala kwe-substrate yensimbi. Ezindaweni zasolwandle nezinosawoti omningi: sebenzisa i-silicone PSA (hhayi i-acrylic), i-PTFE substrate efakwe ngokugcwele, vala imiphetho nge-sealant emelana nesimo sezulu, bese usebenzisa i-primer ezindaweni zensimbi.

Itheyiphu ye-PTFE yokushisa okuphezulu idinga isitoreji esifanele ukugcina ukunamathela kwayo, ukuguquguquka, nokusebenza kokukhishwa. Izidingo ezibalulekile zifaka ukulawulwa kwezinga lokushisa (10-30°C), umswakama ongaphansi kuka-60%, ukugwema ukukhanya, ukuhlukaniswa kwamakhemikhali, ukubekwa okuqondile, kanye nokukhipha umoya. Landela ukuphathwa kwe-inventory ye-FIFO futhi uhlole njalo.
