Gladiator

WhatsApp Order

Gladiator is a high-performance structural adhesive based on methyl methacrylate (MMA) chemistry. Designed as a two-part reactive acrylic system, it offers exceptional bonding strength for demanding industrial and structural applications. With a shear strength exceeding 3,000 psi, Gladiator is particularly effective for bonding metals, plastics, and composite materials. It cures at room temperature and offers excellent resistance to mechanical stress, impact, vibration, and thermal cycling. Widely used in construction, automotive, marine, and maintenance applications, it features rapid setting, gap-filling capacity, and superior durability—even under harsh conditions.

Gladiator

Primary Uses

Construction & Manufacturing

Structural bonding of dissimilar materials such as aluminum, stainless steel, ABS, acrylic, and fiberglass.
Metal fabrication and frame assembly for equipment housings, enclosures, and panel systems.
Composite bonding in architectural panels, doors, and signage applications.
High-performance joining in load-bearing structures, offering mechanical integrity with minimal surface preparation.
Automotive panel and component assembly, including dashboards, brackets, door skins, and body kits.
Replacement for welding or riveting in applications requiring clean aesthetics or minimal thermal distortion.
Bonding of HVAC and ductwork components, providing thermal and vibration resistance.

Secondary Uses

Marine Applications

Boat hull repairs involving composite and metal substrates.
Sealing and bonding in deck fittings, cleats, and interior components.
Underwater or wet-environment curing, making it suitable for emergency patch jobs in marine settings.
Anti-corrosion joining where marine-grade metals or fiberglass are bonded.

DIY & Maintenance

High-strength tool repair, e.g., cracked handles or broken components.
Reinforcement of high-stress joints, such as brackets, frames, and equipment casings.
Adhesive for hobby and crafting where long-term mechanical strength is critical.
Household appliance or utility repairs, especially with dissimilar materials.
