Description
LORD® Signlok™ 810 is a specialty two-component acrylic adhesive designed specifically for ACM (Aluminum Composite Material) and thin-gauge metal-to-metal or metal-to-plastic bonding. Formulated to eliminate bondline read-through, also known as telegraphing, Signlok 810 is the preferred adhesive where clean surface aesthetics are critical—especially in architectural panels and signage.
This adhesive is part of the Signlok 210ml cartridge line (alongside Signlok 403, 406, and 7550), and is compatible with the NEW-3-203-XSP dispensing gun and MCQ 08-24T mixing tip. Whether you’re bonding glossy pre-finished metals or fabricating high-end signage, Signlok 810 offers the flexibility and performance needed for premium visual results.
