Le Fa'aogaina o le Polyester Epoxy Combined Chemistry mo le fa'alavaina o le pauta UV

O le tu'ufa'atasiga o le polyester methacrylated ma le resin epoxy acrylated e ofoina atu se fa'afefiloi manaia o meatotino i le ata fa'amalolo. O le iai o se polyester backbone e maua ai le tete'e lelei o fa'alavalava i su'ega tau. O le ivi epoxy e tu'uina atu ai le fa'agata fa'ama'i, fa'aleleia atili le pipii ma lamolemole. Ose vaega aulelei maketi mo nei UV paʻu paʻu e fai ma sui mo laminates PVC i luga o panels MDF mo fale gaosi meafale.
Ole fa'afefiloi polyester/epoxy e maua ile fa la'asaga tetele.

1. O le polycondensation i le liusuavai o se phthalic dicarboxylic acid derivative (PA) ma se glycol e pei o le neopentyl glycol (PG ) i le 240 °C i le i ai o se esterification catalyst e pei o le butyl stannoic acid e maua ai se polyester fa'amuta carboxy.
2. O le fa'aopoopoina o le glycidylmetacrylate (GMA) i le polyester fa'amuta fa'ameamea fa'ameamea a'o tausia i lalo ole 200 °C. O vaega o le Methacrylate e fa'apipi'i i le pito o filifili polyester e ala i se tali vave o le fa'aopoopoga "epoxy/carboxy". Mo mafuaaga oona, glycidylacrylate e leʻi faʻaaogaina. O le faʻaogaina o fusi faʻalua e aloese mai le faʻaaogaina o inhibitors talafeagai.
3. O le fa'aopoopoina o le acid acid (AA) i se resini diepoxy liusua e maua mai ai se polymer epoxy diacrylate.
4. O le polyester methacrylated ma le resin epoxy acrylated o loʻo faʻafefiloi tutusa e ala i le extrusion.
