Polyurethane sealant (PU Sealants)
Sealant yog ib qho khoom siv los ua voids (qhov, pob yas qej, pob qij, pob qij, thiab lwm yam) thiab muaj ob txoj haujlwm ntawm kev sib txuas thiab sib khi. Polyurethane sealant, silicone sealant thiab polysulfide sealant tshwm sim rau peb yam loj ntawm high-grade sealant.
Polyurethane sealant yog dav siv rau hauv kev ua vaj tsev, tsheb thauj mus los thiab lwm yam lag luam:
Daim ntawv thov nyob rau hauv kev tsim kho - txhaws thiab kaw qhov rooj, qhov rais, iav, thiab lwm yam .;
