Te tono hua

PMAHe whakarewa ahumahi pai rawa atu tēnei, he iti te paitini, ā, he kaha te wairewa mō ngā matū polar me ngā matū kore-polar, ka taea te whakamahi mō ngā peita matatau, te waituhi tā me ētahi atu pūmua, tae atu ki te amido, te methyl ester, te ethyl, te polyester, te cellulose acetate, te glycol acid resin, te crylic acid resin, te epoxy resin me te nitrocellulose, me ētahi atu. Ka taea hoki te whakamahi hei whakarewa mō te peita, te waituhi, te tae kakahu me te hinu miro.

He iti te kakara, he iti te matotoru, he pai te wairewa, he ngawari te mimiti me te pai o te kaha honohono,DPMAKa taea te whakarewa i te nuinga o ngā kapia pēnei i te: kapia kiriaku, te kapia epoxy, te kapia alkyd me te kapia polyester. E whakamahia ana i roto i te peita whakarewa me te waituhi tā mata hiraka. Haunga tēnā, ka taea e ia te whakarewa i te kapia motuhake, ā, ka whakamahia whānuitia i roto i ngā ahumahi kakara me te kakara.
