Izimo Zokucubungula
Shisisa zombili izingxenye (i-isocyanate ne-polyol) ku-73°F(23°C) uma zigcinwa ezingeni lokushisa eliphansi.
Okubalulekile : Nyakazisa ngamandla ingxenye A ngaphambi kwesisindo ngasinye.
Kala izingxenye zombili.
Ngemva degassing imizuzu 10 ngaphansi vacuum mix for
Iminithi elingu-1 nge-PX 226-226
2 amaminithi nge-PX 226-226/L
Faka ngaphansi kwe-vacuum kusikhunta se-silicone, ngaphambilini ebishiswe ku-158°F(70°C).
Khomba ngemva kwemizuzu engu-25 - 60 ubuncane ku-158°F(70°C) (vumela ingxenye ukuthi iphole ngaphambi kokudilizwa).
Ukuphatha Izinyathelo Zokuqapha
Izinyathelo zokuphepha ezijwayelekile kufanele zibhekwe lapho uphatha le mikhiqizo :
Qinisekisa umoya omuhle
Gqoka amagilavu, izibuko zokuphepha kanye nezimpahla ezingenwa amanzi.
Ukuze uthole ulwazi olwengeziwe, sicela ubheke ishidi ledatha yokuphepha.

Izimo zokugcina
Isikhathi seshelufu siyizinyanga eziyisi-6 ingxenye a kanye nezinyanga eziyi-12 engxenyeni b endaweni eyomile nasezitsheni zasekuqaleni ezingavuliwe ezingeni lokushisa eliphakathi kuka-59 no-77°f/(15 kanye no-25° c).Noma iyiphi i-can evuliwe kufanele ivalwe ngokuqinile ngaphansi kwe-nitrogen eyomile.
