Iteyiphu yobushushu obuphezulu be-PTFE inokumelana nokutshiza kwetyuwa ebalaseleyo, kodwa iindawo ezibuthathaka ngumaleko wokuncamathelisa kunye nemiphetho ye-fiberglass substrate. Iindlela zokuvavanya: Uvavanyo lwe-1000h olungathathi hlangothi lwetyuwa yokutshiza (NSS), ukulinganisa ukugcinwa kwamandla e-peel (≥80% efunekayo), iziphene ezibonakalayo (ukuphakamisa, ukugqabhuka), kunye ne-metal substrate corrosion. Kwiindawo zaselwandle kunye netyuwa ephezulu-yenkungu: sebenzisa i-silicone ye-PSA (hayi i-acrylic), i-substrate ye-PTFE efakwe ngokupheleleyo, itywina imiphetho nge-sealant ekwazi ukumelana nemozulu, kwaye usebenzise i-primer kwiindawo zentsimbi.
