Wothandizira makanema ndi gawo lalikulu la chiberekero chagalasi, nthawi zambiri amawerengera 2% mpaka 15% yazovuta za ulusi, ndikupanga zofuna kutetezedwa ndi zinthu zomwe zimachitika muzogulitsa zagalasi. Othandizira makanema omwe amagwiritsa ntchito makanema mu mitsuko yagalasi minyewa ndi ma polima, kuphatikizapo epoxy amayendera, polsulic, zosinthika, zosinthika za polyprocylene, kapena emulsions. Ntchito yopanga mafilimu makamaka imatengera kapangidwe kake ndi kutukwana kwa polymer. Kwa othandizira omwewo-omwewo, kuuma kwaFiberamatha kuwongolera ndi kuchuluka kwa olemera opanga filimu, ndipo othandizira mafilimu omwe ali ndi kulemera kwakukulu kumakhala ndi kufooka kwakukulu kwa galasiKulimbikitsanso zodulidwa za thermoplastic, pomwe wothandizira wa filimu ndi kulemera kwam'munsi ndioyenera kupanga ulusi womwe umagwiritsidwa ntchito poumba ndikuumba. Epoxy restin polims amakhala ndi aliphatic hydroxyl, ma ether, ndi epoxy magemu, ndipo amakhala ndi chidwi chachikulu pakati pa epoxy ndi chomatira ndi ulusi wagalasi;

Kuphatikiza apo, gulu la Epoxy mu EPoxy Offictory Aget Atha Kuchita ndi Gulu la Hydroxyl, gulu lina la Carboxyl, ndi magulu ena ogwirira ntchito mu pct, Othandizira mafilimu okhala ndi ma polyester ali ndi magulu ambiri a ester, zomangira zamankhwala, ndi magulu a hydrophilic m'chipinda chachikulu, ndipo magwiridwe awo amatengera mtundu wa asidi ndi mowa womwe umagwiritsidwa ntchito mu kapangidwe ka polyester ndi kuchuluka kwake. Pamene maziko a polyester sanatheretu, zolumikizira kawiri konse mu Colyerter film-forment ndi zolumikizira ndi zomangira ziwiri zapansi pamunsi kapena kukopeka kwamphamvu, komwe kumapangitsa kugwirizanitsa kwa ma informac. Makina opanga ma polyester nthawi zambiri amakhala ndi zonyowa bwino kwambiri komanso kugwiritsidwa ntchito ngati chonyowa popereka chipongwe, kuwongolera, kupopera, kupopera mbewu mankhwalawa, Chevron, ndi zinthu zina. Polyurethane filimu-forming amtundu wa mankhwala ali ndi kapangidwe kake kabera, komwe kumapangitsa kuti polarethane azikhala ndi zigawo zambiri, nthawi yomweyo, pounion Mankhwala Accorce, Kulimbikitsa Kulumikizana Kwa Kugawana, kukonza magwiridwe antchitoZipangizo ZophatikizikaZogulitsa.
