Litaelo
Ha BG-2655-100 e qhalakanngoa, viscosity ea eona e tla eketseha. Ha e kopantsoe le li-dispersions tsa hydrophilic polyol, e ka hlapolloa ka metsi esale pele kapa ho ka eketsoa mokelikeli o monyenyane ho laola ho eketseha ha viscosity, joalo ka propylene glycol methyl ether acetate (PMA), propylene glycol diacetate (PGDA), le eona. e kgothaletswa ho sebelisa polyurethane grade solvents (metsi a mangata <0.05%) bakeng sa dilution, ka litaba tse tiileng tse seng ka tlase ho 40%. Etsa liteko tse khethehileng le liteko tsa botsitso pele u sebelisoa. Haeba motsoako ka mor'a ho eketsa BG-2655-100, o tlameha ho sebelisoa ka harebophelo ba pitsa.
