Pu Mould Resin
Pu Mould Resin
KAUPAPA
Kei roto ko te waahanga A&B, ko te A he polyol, ko te B ko te Iso-terminated polyurethane prepolymer.
NGA KAUPAPA
He pai rawa nga ahuatanga o te tukatuka, he wa poto, he totoka i te pāmahana noa.Ko te hua kua oti he pai nga ahuatanga o te abrasion resistance, anti-hydrolyzing, transparence, pai te resilience me te rahinga pumau.
TONO
Ka whakamahia mo te hanga hu me nga momo momo PU.Whakakapi i te rapa Silicon ki te hanga i te pokepokea ai o te kohatu ahurea.
PUTANGA
Whakaorangia ki te waahi makariri me te maroke.Ki te kore e taea e koe te whakamahi i te pahū kotahi i te wa kotahi, whakakiia te hau Nitrogen me te hiri pai te pahū.E 6 marama te roanga o te taake taketake.
