Nā Kūlana Hoʻoponopono
E wela i nā ʻāpana ʻelua (isocyanate a me polyol) ma 73°F(23°C) inā mālama ʻia ma ka wela haʻahaʻa.
Mea nui : E lulu ikaika i ka hapa A ma mua o kēlā me kēia kaumaha.
E kaupaona i nā ʻāpana ʻelua.
Ma hope o ka degassing no 10 mau minuke ma lalo o ka hoʻoheheʻe ʻia ʻana no

2 minuke me PX 226-226/L
E hoʻolei ʻia ma lalo o ka ʻūhā i loko o kahi poʻi silicone, i hoʻomehana ʻia ma 158°F(70°C).
E hoʻoemi ma hope o 25 - 60 minuke ka liʻiliʻi ma 158°F(70°C) (e ʻae i ka ʻāpana e maʻalili ma mua o ka wehe ʻana).
