Kugwiritsa ntchito

UV- 329 ndi chithunzi chokhazikika chapadera chomwe chimagwira ntchito pamakina osiyanasiyana a polymeric: makamaka ma polyesters, polyvinyl chlorides, styrenics, acrylics, polycarbonates, ndi polyvinyl butyal. UV-329 imadziwika kwambiri chifukwa cha kuyamwa kwake kosiyanasiyana kwa UV, mtundu wocheperako, kusasunthika kochepa, komanso kusungunuka kwabwino kwambiri. Zomwe zimagwiritsidwa ntchito pomaliza zimaphatikizapo kuumba, mapepala, ndi zinthu zowala zowunikira mazenera, chizindikiro, ntchito zapamadzi ndi zamagalimoto. Mapulogalamu apadera a UV- 5411 amaphatikiza zokutira (makamaka ma themoset pomwe kutsika kudali kodetsa nkhawa), zithunzi, zosindikizira, ndi zida za elastomeric.
