Lord Adhesives 852 Toughened Structural Acrylic Adhesive with Lord Accelerator 25GB Adhesive System
Categories: Polymer; Thermoset; Acrylic/Cyanoacrylate Adhesive

Material Notes: LORD® 850 and 852 acrylic adhesives in combination with LORD Accelerator 25GB can be used to replace welding, brazing, riveting and other mechanical fastening methods. These toughened structural adhesives perform particularly well in low-temperature environments and applications that are subject to high impact, high peel loads or high fatigue. LORD 850 and 852 adhesives provide a range of working times to accommodate a wide variety of process requirements. LORD 850 and 852 adhesives, when mixed with LORD Accelerator 25GB, create adhesive systems that bond a wide variety of prepared or unprepared metals and some engineered plastics. These adhesive systems are 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.

Features: bonds a wide range of unprepared metals with minimal substrate preparation, as well as polymer composite substrates such as FRP. provides high strength for high-end structural bonding applications; 100% elongation improves impact strength and fatigue resistance. 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). resists dilute acids, alkalis, solvents, greases, oils, moisture, salt spray and weathering; provides excellent resistance to indirect UV exposure. remains in position when applied on vertical or overhead surfaces, allowing for greater process flexibility.
