Tukatuka Tikanga
Whakawerahia nga wahanga e rua (isocyanate me te polyol) ki te 73°F(23°C) ki te rokiroki i te pāmahana iti.
He mea nui : Kia kaha te ruru i te wahanga A i mua i ia paunatanga.
Paunatia nga wahanga e rua.
I muri degassing mo te 10 meneti i raro i korehau ranunga mo
1 meneti me te PX 226-226
2 meneti me te PX 226-226/L
Maka i raro i te korehau i roto i te pokepokea silicone, i whakamahana i mua ki te 158°F(70°C).
Whakawetohia i muri i te 25 - 60 meneti iti rawa i te 158°F(70°C) (whakaaetia kia whakamatao te wahanga i mua i te turaki).
Te Whakahaere Whakatupato
Ko nga tikanga mo te hauora me te haumaru me mau ki te whakahaere i enei hua:
Me whakarite kia pai te hau
Mau karapu, karaehe haumaru me nga kakahu parepare.
Mo etahi atu korero, tirohia te pepa raraunga haumaru rawa.

Nga tikanga rokiroki
E 6 marama te ora mo te wahanga a me te 12 marama mo te wahanga b i te waahi maroke me nga ipu taketake kare ano i tuwhera i te mahana kei waenga i te 59 me te 77°f/(15 me te 25°c).Ko nga ipu kua tuwhera me tino kati i raro i te hauota maroke.
