Parker LORD® Structural Adhesives

Precision Adhesives for Sign Fabricators.

Stronger Bonds. Cleaner Aesthetics. Faster Builds.

LORD® Signlok™ adhesives control costs, reduce waste, and enhance productivity and performance by replacing welding, riveting, and other traditional mechanical fasteners.

LORD Signlok Adhesive Series

The Cost of Mechanical Fastening

  • Wasted Labor: Welding aluminum and steel requires highly skilled labor, specialized equipment, and extensive post-weld grinding.
  • Poor Aesthetics: Rivets, screws, and weld marks interrupt clean designs and require patching or filling before paint.
  • Material Limitations: Traditional fasteners struggle to cleanly join dissimilar materials like ACM panels to raw aluminum frames.

The Signlok™ Advantage

  • Invisible Bonds: Achieve smooth, flush finishes with no read-through on thin-gauge metals or ACM panels.
  • Built-In Spacing: Contains glass beads to enable precision bondline control and manage waste.
  • Minimal Prep: Requires minimal surface preparation. Remove grease, loose contamination, or poorly adhering oxides.
  • Universal Dispensing: Utilizes one set of dispensing equipment for a variety of products and jobs.
