Development of a new coating raw material based on a mixture of epoxidized palm olein and diglycidyl ether of bisphenol a / Reihan Mohd Taharim

Epoxy coatings are highly in demand due to their excellent corrosion protective properties. Currently, raw materials for epoxy coatings mainly originate from diglycidyl ether of bisphenol A (DGEBA), a compound derived from petrochemicals. However, health concerns associated with bisphenol A, combine...
