I-Absorption ye-UV i-UV-928 yi-benzotriazole i-Absorption ye-UV, ekwazi ukufunxa i-270-380 nm ukukhanya kwe-ultraviolet, kunye nesantya esiphezulu se-303 nm kunye ne-345 nm. Ineempawu zokuhambelana kakuhle, ukuguquguquka okuphantsi, ukusasazwa kakuhle, ukuhamba okuphantsi, ukuzinza okuhle kwe-thermal kunye nokusebenza kakuhle kokufunxa, kwaye ifanelekile kwinkqubo yokunyanga ubushushu obuphezulu, i-powder yokugqoka kunye ne-rolling steel coating. Idityaniswe ne-UV292 yokukhanya kunye ne-UV123, iphucula kakhulu ukuqina kwengubo, kwaye inqanda ukulahleka kokukhanya kokukhanya, ukuguquka kombala, ukuqhekeka, kunye ne-delamination.
Isetyenziswa kakhulu kwi: i-automotive coating, icoil coil, i-powder coating.
Isixa esicetyiswayo: 1.0-3.0%, isixa esithile sinqunywe ngokuhambelana novavanyo lwesicelo somthengi
Ipakishwe kwi-20 okanye i-25 Kg / ibhokisi.
Gcina kwindawo epholileyo, eyomileyo kwaye engenamoya; kuphephe ukukhanya kwelanga.
Nceda uqhagamshelane nathi ngawo nawaphi na amaxwebhu anxulumeneyo.
I-New Venture Enterprise izinikele ekuboneleleni ngezizinzisi zokukhanya ezikumgangatho ophezulu ukuhlangabezana neemfuno ezahlukeneyo zala mashishini, ukuqhuba ukutsha kunye nokuzinza kuphuhliso lwemveliso, nceda uqhagamshelane nathi:
