Pu Mold Resin
Pu Mold Resin
COMPOSITION
Ili ndi gawo la A&B, A ndi polyol, ndipo B ndi Iso-terminated polyurethane prepolymer.
MAKHALIDWE
Ili ndi katundu wabwino kwambiri wopangira, nthawi yayitali ya gel osakaniza, yolimba pakutentha wamba.Chomalizidwacho chimakhala ndi zinthu zabwino zotsutsana ndi abrasion, anti-hydrolyzing, kuwonekera, kulimba mtima komanso mawonekedwe okhazikika.
APPLICATION
Amagwiritsidwa ntchito popanga nsapato ndi mitundu yosiyanasiyana ya PU.M'malo mwa mphira wa Silicon kuti apange nkhungu yamwala wachikhalidwe.
KUSINTHA
Sungani pamalo ozizira ndi owuma.Ngati simungathe kugwiritsa ntchito ng'oma imodzi nthawi imodzi, chonde dzazani mpweya wa nayitrojeni ndikumata bwino mgolowo.Nthawi ya alumali yonyamula koyambirira ndi miyezi 6.
