Thepi ya mahiselo yale henhla ya PTFE yina ku tiya ka kahle swinene ka munyu, kambe tindzhawu letinga tsana i leyara yo namarhela xikan’we na makumu ya fiberglass substrate. Maendlelo yo kambela: 1000h neutral salt spray (NSS) test, ku pima ku khomiwa ka matimba ya peel (≥80% swa laveka), ku tsandzeka ku vona (ku tlakusa, ku pfimba), na metal substrate corrosion. Eka tindzhawu tale lwandle na letingana nkungu wa munyu wotala: tirhisa silicone PSA (hayi acrylic), PTFE substrate leyi cheriweke hiku hetiseka, pfalela makumu hi sealant leyinga tiyisela maxelo, naswona chela primer eka swiphemu swa nsimbi.

Thepi ya mahiselo yale henhla ya PTFE yi lava vuhlayiselo lebyi faneleke ku hlayisa ku namarhela ka yona, ku olova, na matirhelo ya ku humesa. Swilaveko swa nkoka swikatsa vulawuri bya mahiselo (10-30°C), ndzhongho wale hansi ka 60%, ku papalata ku vonakala, ku hambanisiwa ka ti khemikhali, ku vekiwa hiku yima, xikan’we naku nghenisiwa ka moya. Landzelela vulawuri bya nhundzu ya FIFO naswona u kambela nkarhi na nkarhi.
