LORD® 850 Toughened Structural Acrylic Adhesive Where To Buy

Product Information

LORD® 850 acrylic adhesive in combination with LORD Accelerator 25GB can be used to replace welding, brazing, riveting and other mechanical fastening methods. This toughened structural adhesive performs particularly well in low-temperature environments and applications that are subject to high impact, high peel loads or high fatigue.

LORD 850 adhesive, when mixed with LORD Accelerator 25GB, creates an adhesive system that bonds a wide variety of prepared or unprepared metals and some engineered plastics. This adhesive system is specifically formulated to provide the highest impact and peel strengths available in a room temperature curing adhesive with exceptional cohesive failure mode.

LORD Accelerator 25GB allows precise control of the adhesive bondline thickness due to its content of glass beads. For further detailed information, refer to the LORD Accelerator 25GB data sheet.

Shelf Life

Shelf life is six months when stored below 77°F (25°C) in original, unopened container. Storage temperatures of 40-50°F (4-10°C) are recommended. If stored cold, allow product to return to room temperature before using. Protect from exposure to direct sunlight.

LORD 850 adhesive is flammable. Do not store or use near heat, sparks or open flame.

Features and Benefits

Versatile - bonds a wide range of unprepared metals with minimal substrate preparation, as well as polymer composite substrates such as FRP.

Durable - provides high strength for high-end structural bonding applications; 100% elongation improves impact strength and fatigue resistance.

Temperature Resistant - performs at temperatures from -40°F to +300°F (-40°C to +149°C); tolerates e-coat bake with cohesive failure at 338°F (170°C).
Note: Based on test results, LORD 850/25GB adhesive system exhibits post bake/powder coating temperature resistance up to 400°F (204°C) for 90 minutes. Customer specific substrates should always be evaluated for specific application performance.

Environmentally Resistant - resists dilute acids, alkalis, solvents, greases, oils, moisture, salt spray and weathering; provides excellent resistance to indirect UV exposure.

Non-Sag - remains in position when applied on vertical or overhead surfaces, allowing for greater process flexibility.
