Isticmaal
Badeecadani waa xasiliye iftiin leh oo leh waxqabad wanaagsan, oo awood u leh inuu nuugo shucaaca UV ee hirarka 240-340 nm oo leh astaamaha midabka iftiinka, aan sun ahayn, iswaafajin wanaagsan, dhaqdhaqaaq yar, habayn fudud iwm. Waxay ilaalin kartaa polymer-ka ilaa heerka ugu sarreeya, waxay gacan ka geysaneysaa yareynta midabka. Waxay sidoo kale dib u dhigi kartaa huruudaynta waxayna caqabad ku noqon kartaa luminta shaqadiisa jireed. Waxaa si weyn loogu dabaqaa PE, PVC, PP, PS, galaaska dabiiciga ah ee PC, polypropylene fiber, ethylene-vinyl acetate iwm. Intaa waxaa dheer, waxay leedahay saameyn aad u wanaagsan oo xasillooni iftiin ah oo ku saabsan qalajinta phenol aldehyde, varnish of alcohol and acname, polyurethane, acrylate, expoxnamee iwm.
