Features and Benefits
Strong Mechanical Lock – contains glass beads which provide a mechanical lock that will prevent shifting of substrate panels.
Easy to Apply – utilizes non-sagging rheology; replaces the need for spot welding which degrades metal and allows rusting to occur.
High Impact Resistant – delivers excellent dynamic resistance to cleavage under ISO 11343:2003.
Low Temperature Cure – develops a high strength bond in one hour at room temperature, eliminating metal warpage caused by high curing induction temperatures. Induction heating should be conducted at 110°C (230°F) or below.
Bonds Unprepared Metals – bonds exceptionally well through the various stamping lubricants typically present on metals, eliminating the need for advance cleaning and surface preparation.
Environmentally Resistant – provides excellent resistance to moisture, sunlight, salt spray and thermal cycling; sustains short exposure to postbakes up to 204°C (400°F).
