Adhesive RFE / DESMODUR RFE CAS 4151-51-3

Cov lus piav qhia luv luv:

Ob-xaim nplaum yuav tsum siv nyob rau hauv lub sijhawm siv tom qab muab tso tom qab tso rau hauv RFE. Lub sijhawm siv tau ntev tsis tsuas yog cuam tshuam nrog cov ntsiab lus polymer ntawm cov nplaum, tab sis kuj tseem muaj lwm cov khoom sib txuas (Zoo li rov ua dua, antioxygen, plasticizer, kuab tshuaj, thiab lwm yam.) Thaum ze rau lub sijhawm siv, feem ntau yog ob peb teev lossis ib hnub ua haujlwm, cov nplaum ua qhov nyuaj dua rau kev khiav lag luam, thiab viscosity nce sai sai, Thaum kawg, nws tiav niam txiv tsis tuaj yeem ua tiav.100 zoo nplaum, Hydroxyl polyurethane (Polyurethane tus account rau ib ncig 20%), RFE koob 4-7. Chloroprene roj hmab (Cov roj hmab account rau ib ncig 20%) , Peb RFE koob 4-7.
