Isicelo

I-UV Stabilizer i-UV-1 sisongezo esisebenzayo sokulwa ne-ultraviolet. I-Uv-1 ikwasetyenziswa kwizixhobo ze-polyurethane ezifana negwebu logwebu, ii-elastomers, ufele, izihlangu, izinto zokuncamathelisa, iingubo njalo njalo. Ngaphandle koko, i-UV stabilizer UV-1 iyakwazi ukuphucula ngokufanelekileyo ukuxhathisa ukutyheli kweemveliso.
