DuPont BETAMATE™ 73345G Epoxy (discontinued **)
Categories:	Polymer; Thermoset; Epoxy
Material Notes:	BETAMATE™ 73345G is a one-part, high performance, heat curing, epoxy adhesive. It is capable of bonding oily galvanized and cold rolled steel without a primer and has corrosion resistance. BETAMATE™ 73345G also has sag resistance and peel strength. It accepts E-coat primer which also enhances corrosion resistance and reduces shadowing. It can be gelled to give handling strength by induction or use of hot air. If desired, handling strength can be achieved by controlling hemming pressure as the glass beads in the product will provide a mechanical lock-up of hems. Information provided by Dow This former Dow product line is now a DuPont product line.
