Fa'asao: 207 °F
Tulaga Teuina: Teu i totonu o se faleteuoloa malulu ma fa'aalili. Taofi ese mai le afi ma le vevela. Taofi ese mai le malamalama. O le vevela o le faatanoa e le tatau ona sili atu i le 30 ℃. Taofi fa'amaufa'ailoga pusa ma 'alofia le pa'i atu i le ea.
Paketi: E maua i le 200 Kg pa'u po'o fa'apipi'i fa'apitoa filifiliga.
Talosaga:
Gaosiga o Resins Acrylic: O le HEMA e taua tele i le gaosia o vaega malosi ole hydroxyethyl acrylic resin, faʻafaigofieina le faʻatulagaina o faʻamau faʻafefe.
Alamanuia Coatings: E maua ai le tele o le fa'aoga i fa'alavalava, e saofagā i le fa'aleleia atili o le tumau ma le fa'atinoga.
Alamanuia Suau'u: Auauna atu o se fa'aopoopoga i le lubricating suau'u fufulu faiga, fa'aleleia lelei ma le umi.
Lua-vaega Coatings: Vaega taua i le gaosiga o mea e lua-vaega faʻapipiʻi, faʻamautinoa le malosi ma le umi.
Manatuga mo le Saogalemu:
Mata'utia o le Ea: HEMA e ma'ale'ale le ea; o le mea lea, e tatau ona fa'aeteete e puipuia ai fa'alavelave e le mana'omia.
Tulaga mautu: E mafai ona fa'apolopoloina pe a leai ni fa'amautu; o lea, e mana'omia ai faiga fa'amautu talafeagai.
Le fetaui lelei: Aloese mai le fa'afeso'ota'i ma vaila'au fa'ama'i malolosi, fa'atupu fa'ama'i fa'asa'oloto, ma peroxyide e puipuia ai fa'alavelave mata'utia.
I le faaiuga, o le 2-Hydroxyethyl Methacrylate (HEMA) o loʻo tu o se maatulimanu i faiga faʻapisinisi eseese, ofoina atu le faʻamaoni, agavaʻa, ma le aoga. Faatasi ai ma le tele o faʻaoga eseese ma faiga faʻapolopolo saogalemu, o loʻo faʻaauau pea ona vaneina e le HEMA lona faʻailoga i le laufanua vailaʻau, faʻamalosia mea fou ma le alualu i luma i pisinisi i le lalolagi atoa.
