6. Resin epoxy na gama gari, wakilai masu warkarwa da ƙari suna da asali da yawa, babban samarwa, mai sauƙin ƙirƙira, ana iya yin ƙera matsin lamba ta hanyar tuntuɓar juna, ana iya amfani da su a babban sikelin.

Yadda ake zaɓaresin epoxy

Lokacin zabar resin epoxy, akwai abubuwa da yawa da za a yi la'akari da su, gami da:

1. Amfani: Za a iya amfani da epoxy don amfani na gaba ɗaya ko ƙarin aikace-aikacen masana'antu?
2. Rayuwar Aiki: Har yaushe za a buƙaci a yi amfani da epoxy kafin a warke?
3. Lokacin Warkewa: Har yaushe zai ɗauki samfurin ya warke kuma ya warke gaba ɗaya ta amfani da epoxy?
4. Zafin Jiki: A wane zafin jiki ne sashin zai yi aiki? Idan ana son siffa, shin an gwada epoxy ɗin da aka zaɓa don tantance yanayin zafi?

Halaye:

• Babban halayen thixotropic, ana iya amfani da shi don gina façade.
• Babban halayen aminci ga muhalli (tsarin warkarwa mara narkewa).
• Babban sassauci.
• Babban ƙarfin haɗin kai.
• Babban rufin lantarki.
• Kyakkyawan kayan aikin injiniya.
• Kyakkyawan zafin jiki da juriya ga ruwa.
