LORD Signlok 810 (210mL Cartridge) Non-Sag MediumSet 8-12 min MMA adhesive

Product Name

- LORD Signlok 810 (210mL Cartridge) Non-Sag MediumSet 8-12 min MMA adhesive

Brief Description

- LORD Signlok 810 is a two-component, non-sag, medium-set Methyl Methacrylate (MMA) adhesive system. It is engineered for high-performance structural bonding of a wide range of metals and engineered plastics. This adhesive is particularly noted for its fast cure speed, strong bonding, and minimal bondline read-through (BLRT), making it ideal for applications where aesthetic appearance is critical.

Popular Applications & Uses

- Bonding Aluminum Composite Material (ACM) panels to frames and structures.- Assembly of sign boxes, channel letters, and structural skins.- Bonding glossy or pre-finished metals where visual quality is key.- Architectural cladding systems where welding is not feasible.- Cross-bonding metal to engineered plastics.- Automotive and transport applications, including attaching panels and brackets.- Minivan manufacturing for bonding composite flooring to wood.

Industries that Commonly Use It

- Sign & Display- Metal Fabrication- Plastic Fabrication- Construction/ Building Services (specifically for architectural cladding and bonding panels to buildings)- Transportation/ Specialty Vehicle (automotive, bus, minivan manufacturing)- General Manufacturing

Special and Unique Features

- Low Bondline Read-Through (BLRT) formula, preventing surface distortion on thin and flexible substrates like ACM and glossy panels.- Non-Sag formulation, allowing it to remain in position on vertical or overhead surfaces for greater process flexibility.- Contains glass beads to ensure precise bondline thickness and material control, and to insulate against galvanic corrosion.- Requires little to no substrate preparation for bonding metals and plastics.- UL 746C Recognized, approved for use in UL-listed sign and enclosure assemblies.- Flexible and durable with 190% elongation, allowing bonding of thin and flexible materials without cracking.

Known backups / known substitutes

- LORD Signlok 403: Rapid cure for structural bonding of metal and plastic.- LORD Signlok 406: High-strength acrylic adhesive for bonding metal and plastics.- LORD Maxlok MX/T3, MX/T6, MX/T18: Tough, high-strength acrylic adhesives designed to replace welding, brazing, and riveting, offering superior impact and peel resistance with varying work times.- Other MMA adhesives from brands like Permabond, ASI, Plexus, Sika, Loctite, Infinity Bond.

Comparison Note

- LORD Signlok 810 is specifically formulated to prevent bondline read-through on thin-gauge metals and ACM, a key differentiator for aesthetic applications compared to some other structural adhesives. While other MMA adhesives offer strong bonds and fast cure, Signlok 810's emphasis on aesthetics and minimal surface preparation makes it particularly suitable for the sign and architectural industries.
