Molecular Structure


Syna-Epoxy-28E is an electronic grade SYNA-28. It is a standard cycloaliphatic epoxy resin. It can be used in high viscosity demand areas and in flexible film materials such as cationic inks, dual-cure adhesives, shock-resistant foams for mounting equipment to be shockproof during satellite launch. Its difference from ordinary SYNA-28 is the control of total chlorine.
Conventional applications include metal decorative coatings, varnish, and flexible packaging composite adhesives.
