Pu Shoe Upper Resin
Pu Shoe Upper Resin
COMPOSITION
Iyi sisitimu ine zvikamu zvina, polyol, ISO, kurapa agent uye catalyst.
ZVINHU
Kusanganisa Tembiricha 30～40℃, Kurapa Tembiricha 80℃90℃, Demould nguva 8～10 min (inochinjika), Kuoma kwechigadzirwa chakapedzwa kunogona kugadziriswa nekushandura chiyero chemidziyo yechikamu A+C/B.
STORAGE
Chengetedza munzvimbo inotonhorera uye yakaoma.Kana usingakwanise kushandisa dhiramu rimwe chete panguva imwe, ndapota zadza gasi reNitrogen uye uname dhiramu racho zvakanaka.Hupenyu hwesherufu hwekutanga kurongedza ndeye 6 mwedzi.
