Txawm li cas los xij, seb polyurethane sealant zoo dua li silicone sealant nyob ntawm daim ntawv thov tshwj xeeb thiab cov cai. Nov yog qee qhov sib txawv tseem ceeb los xav txog:
Adhesion: Polyurethane sealantsfeem ntau muaj qhov zoo dua adhesion rau ntau qhov chaw, suav nrog ntoo, hlau, thiab pob zeb, ua rau lawv tsim nyog rau kev thov ntau dua.
Flexibility:Ob leeg sealants muaj kev yooj yim, tab sis polyurethane nyhav dua elastic, cia nws nqus txav tau zoo dua, uas muaj txiaj ntsig zoo hauv thaj chaw muaj kev nthuav dav thiab kev cog lus.
Durability:Polyurethane sealants feem ntau siv tau ntev dua thiab tiv taus kev puas tsuaj, tshuaj lom neeg, thiab UV raug, ua rau lawv zoo tagnrho rau kev siv sab nraum zoov thiab kev lag luam.
Dej tsis kam:Ob hom muab cov dej tsis zoo, tab sis polyurethane sealants feem ntau ua tau zoo dua hauv cov dej ntub dej thiab tuaj yeem tiv taus cov dej noo ntev.
Lub sijhawm kho:Silicone sealants feem ntau kho sai dua polyurethane sealants, uas tuaj yeem ua tau zoo dua hauv cov haujlwm tseem ceeb hauv lub sijhawm.
Kev zoo nkauj:Silicone sealants muaj nyob rau hauv ntau yam xim thiab tuaj yeem ua kom zoo nkauj dua rau cov ntawv pom, thaum polyurethane sealants yuav xav tau pleev xim rau qhov zoo.
Temperature Resistance: Silicone sealants feem ntau muaj qhov zoo dua qhov kub thiab txias, ua rau lawv haum rau cov ntawv thov raug tshav kub.
