Pu Pwm Resin
Pu Pwm Resin
COMPOSITION
Nws muaj A & B tivthaiv, A yog polyol, thiab B yog Iso-terminated polyurethane prepolymer.
CHARACTERISTIS
Nws muaj cov khoom ua haujlwm zoo, lub sijhawm luv gel, khoom hauv qhov kub thiab txias.Cov khoom tiav lawm muaj cov khoom zoo ntawm kev puas tsuaj, tiv thaiv hydrolyzing, transparence, zoo resilience thiab ruaj khov dimension.
APPLICATION
Siv los ua khau thiab ntau hom PU pwm.Hloov ntawm Silicon roj hmab los ua cov pwm ntawm kab lis kev cai pob zeb.
KHOOM
Khaws rau hauv qhov chaw txias thiab qhuav.Yog tias koj siv tsis tau ib lub nruas ib zaug, thov sau Nitrogen roj thiab kaw lub nruas kom zoo.Lub neej txee ntawm cov khoom qub yog 6 lub hlis.
