Versilok® 253LGB/254 Adhesive
LORD Versilok® 253LGB/254 adhesive is a two-component, epoxy-modified acrylic adhesive used to bond a variety of automotive sheet metals, including hot-dip galvanized, electro-galvanized, bare aluminum, and cold rolled steel. Versilok 253LGB/254 adhesive can be either room temperature cured or heat cured for faster processing.
Glass beads are included in the adhesive system providing a mechanical lock between substrates. For customized dispensing, Versilok 253LGB/254 adhesive contains a lower level of glass beads compared to other Versilok adhesives.
Versilok 253LGB/254 adhesive is approved by Mercedes-Benz AG.
Shelf life is six months from date of shipment when stored at 25°C (77°F) in original, unopened container.
Features and Benefits
• Easy to Apply - utilizes non-sagging rheology; replaces the need for spot welding which degrades metal and allows rusting to occur.
• Strong Mechanical Lock - contains glass beads which provide a mechanical lock that will prevent shifting of substrate panels. • Low Temperature Cure - develops a high strength bond in less than one hour at room temperature, eliminating metal warpage caused by high curing induction temperatures and allowing assemblies to be handled prior to the E-coat prime or bake process.
• 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).
