Product Description
LORD® 810S paired with LORD Accelerator 20GB, creates a high-performance, flexible acrylic adhesive system specifically engineered for thin-gauge substrates. This "Low Read-Through" (LRT) formula is designed to bond metals and engineered plastics without the surface distortions or "ghosting" typically caused by exothermic heat during the curing process. By incorporating specialized glass beads, LORD®810S/20GB ensures a uniform, controlled bondline thickness every time, making it the premier choice for visible, high-aesthetic assemblies.
Product Key Features
- Superior Aesthetics (LRT) – bonds thin and flexible substrates with little to no bondline read-through.
- Precision Bondline Control – contains integrated glass beads in the Accelerator 20GB to maintain exact adhesive thickness and prevent over-clamping.
- Non-Sag - remains in place on vertical or overhead surfaces to support bead control during assembly.
- Environmental Resistance - cured adhesive resists weathering, humidity, salt spray, and many solvents.
Applications
This adhesive fits composite and mixed-material assemblies that require structural bonding, controlled bead placement, and curative options matched to production timing.
- Thin-Gauge Metal Assembly: bonding aluminum and galvanized steel panels where welding would cause warping or require extensive post-finishing.
- Engineered Plastics: provides high-strength, flexible bonds for materials like PC-ABS and other plastics with simple cleaning.
- Outdoor & Industrial Equipment: resists weathering, indirect UV exposure, dilute acids, and solvents, making it ideal for enclosures and exterior signage.

Additional Information
LORD® 810S / Accelerator 20GB
LORD® 810S is a flexible, Low Read-Through (LRT) acrylic adhesive system specifically engineered for bonding thin-gauge metals and engineered plastics like PC-ABS. When paired with LORD Accelerator 20GB, it provides high-speed structural bonding with minimal surface distortion. The system features integrated glass beads for precise bondline control and excels at cutting through mill oils, reducing the need for extensive substrate preparation.
Key Features
- Aesthetics: Bonds thin substrates with little to no bondline read-through (BLRT).
- Integrated Glass Beads: Accelerator 20GB ensures precise and consistent bondline thickness.
- Low Prep: Excellent adhesion to "as-received" metals with standard mill oils.
- Fast Cure: Achieves 90% strength in 30 minutes at room temperature.
- Resilience: Resists dilute acids, solvents, UV exposure, and weathering.

Process Notes
- Remove grease, dirt, and poorly adhering oxides.
- Mill oils typically do not require removal for metal bonding.
- Plastics usually require simple cleaning; some may need abrasion.
- Ensure 2:1 ratio (Adhesive:Accelerator).
- Level plungers before attaching mixer.
- Handheld cartridges or meter/mix equipment are compatible.
- Clean uncured adhesive with IPA, Acetone, or MEK.
- To separate cured parts, heat to 400°F (204°C) to soften the bond.
