Kugwiritsa ntchito

PM-200 ingagwiritsidwe ntchito kwambiri popanga zinthu zoteteza thovu zolimba za polyurethane; Ingagwiritsidwenso ntchito mu thovu la isocyanurate, zokutira, zomatira, zotchingira zoteteza madzi, thovu lomangira, thovu la khungu lokhala ndi pobowola, ma bumpers agalimoto, ziwalo zamkati, thovu lolimba kwambiri, matabwa opangidwa ndi zinthu zina. Chifukwa cha kapangidwe kake kapadera, ili ndi mphamvu zabwino zotulutsa thovu, ndipo ndi yoyeneranso kupanga zinthu zomwe zimafunikira kuti thovu lizitha kutulutsa madzi.
