CYASORB UV-3638 CAS 18600-59-4 ke eng?

Light stabilizer 3638 ke boima bo phahameng ba limolek'hule, bofokoli bo tlaase le letheba le se nang mebala. Haholo-holo e loketse litlhoko tse phahameng tsa 'mala oa phetisetso ea indasteri ea optical. Light stabilizer 3638 e na le stabilizer e phahameng ea mocheso e nang le TGA (10%) e kholo ho feta likhato tse 371 tsa Celsius. Light stabilizer 3638 ke moloko o mocha oa mohanyi o sebetsang hantle oa ultraviolet, o se nang tikoloho ebile o sebetsa hantle. Bakeng sa UVB, UVC e na le bokhoni bo phahameng ba ho monya.
