Pū pūnaha hu haumaru Pu
INtroduction
Ko te punaha Pu Haumaru-FIFE e whakamahia ana hei hanga i nga momo hu haumaru me nga papa o roto. He rauemi pūnaha Porata-a-Polyester, e wha nga waahanga, Plylyol, ISO, uaua me te catalyst. Ko te tukatuka o te punaha e rua nga waahanga. Ko te Catalyst, he uaua, te pupuhi o te kaihoko me te poaka kia whakaranuhia ki te Porohiko Pakeke Ex-3270A, ka uru ki te waahanga ISO Extra-3119B mo te hanga taonga whakamutunga.
