Polyurea Txheej rau Waterproof Sealant Khoom Series
TSW-601
Taw qhia
DSPU-601 yog ob lub ntsiab lus polyurea tshuaj tsuag hom kev sib xyaw ua ke, uas yog siv ntau yam khoom siv tiv thaiv.100% cov ntsiab lus khoom, tsis muaj kuab tshuaj, tsis muaj volatile, me me los yog tsis muaj ntxhiab, nruj me ntsis raws li VOC txwv tus qauv, belongs rau ib puag ncig cov ntaub ntawv.

KHOOM PLIG
200kg / nruas
KHOOM
B tivthaiv (isocyanate) yog noo noo rhiab heev.Cov khoom siv raw uas tsis siv yuav tsum tau muab khaws cia rau hauv lub nruas kaw, tsis txhob ya raws .Ib feem (polyether) yuav tsum do zoo ua ntej siv.
Ntim
DTPU-401 raug kaw hauv 20kg lossis 22.5kg pails thiab thauj hauv rooj ntoo.
TSEEM CEEB
Ntu B (isocyanates) txhawb lub qhov muag, ua pa thiab tawv nqaij los ntawm kev ua pa thiab sib cuag ntawm daim tawv nqaij, thiab tejzaum nws rhiab heev.
Thaum tiv tauj rau ntu B (isocyanates), kev tiv thaiv tsim nyog yuav tsum tau ua raws li cov ntaub ntawv kev nyab xeeb cov ntaub ntawv (MSDS).
NYIAJ NYIAJ
Nrog rau kev siv cov ntaub ntawv kev nyab xeeb ntawm cov khoom (MSDS) ntawm cov khoom, lossis ua raws li cov cai hauv zos thiab cov cai.
