ER2218 Black Epoxy Resin

In Stock

ER2218 is a low viscosity epoxy resin with excellent thermal stability. The product has been specifically designed for compatibility with reflow applications, therefore remaining stable for short term, high temperature excursions. The system utilises a hardener free of DDM or other aromatic amines. The flame retardant filler used is a non-halogenated ‘clean’ type leading to relatively low toxicity fumes and low smoke emission.
