Lord Adhesives Signlok 810 Adhesive System
Categories: Polymer; Adhesive; Thermoset

Material Notes: LORD® Signlok™ 810 adhesive is a two-component adhesive system designed for bonding metals, such as aluminum, aluminum composite material (ACM), galvanized steel and CRS, and engineered plastics, such as PC-ABS**. LORD Signlok 810 adhesive delivers fast cure speed and strong bonding with minimal bondline read-through (BLRT). LORD Signlok 810 adhesive is flammable. Do not store or use near heat, sparks or open flame.

Features: bonds thin and flexible substrates with little to no bondline read-through. requires little or no substrate preparation for bonding metals and plastics. remains in position when applied on vertical or overhead surfaces, allowing for greater process flexibility. allows precise control of the adhesive bondline thickness due to its content of glass beads. resists dilute acids, alkalis, solvents, greases, oils and moisture; provides excellent resistance to UV exposure and weathering. UL 746C certified.
