WHAKATOKANGA

Ko te DonSpray504 he polyols whakakotahitanga rehu, he 245fa te kaihoko pupuhi hei utu mo te HCFC-141B, ka tauhohe ki te isocyanate ki te whakaputa pahuka he pai nga mahi, e whai ake nei,

1) pūtau pai me te riterite

2) iti te kawe waiariki

3) tino parenga mura

4) pai te pūmautanga inenga iti-mahana.

E pa ana ki nga momo miihini whakawera waiariki e whakamahi ana i te hangarau rehu, penei i nga ruuma makariri, nga kohua, nga paipa nui-nui me te hanga metope etc.
