Assembly Adhesive Soudal T-REX 380 g — high-strength construction adhesive cartridge

Soudal T-REX 380 g is a high-strength assembly adhesive supplied in a cartridge for use with a standard caulking gun. Designed for structural bonding in construction, renovation and repair projects, this adhesive bonds a wide range of common building materials including metals, wood, concrete, stone and many plastics. The formulation offers strong initial grab, durable adhesion under load and suitability for both indoor and outdoor applications where a long-lasting, load-bearing joint is needed.

Advantages

The adhesive provides high bonding strength and good gap-filling capability, allowing secure joins even on uneven surfaces. It achieves rapid initial tack to reduce the need for temporary mechanical supports and develops a resilient, weather-resistant bond that withstands typical construction stresses. The cartridge format enables use with standard applicator guns for controlled, continuous dispensing and accurate bead placement.

Suitable for

• Bonding metal components such as profiles, brackets and trim
• Joining timber elements, panels and laminated products
• Fixing concrete, masonry and stone elements in repairs and assemblies
• Adhering many types of rigid plastics to other substrates
• Indoor and outdoor structural bonding where mechanical fasteners are impractical

Key specifications

• Form: cartridge for caulking gun application
• Net content: 380 g
• Performance: high-strength assembly adhesive with strong initial tack
• Compatibility: bonds metals, wood, concrete, stone and various plastics
• Application conditions: suitable for interior and exterior use
• Curing: forms a durable, load-bearing elastic bond after curing

How to use

Prepare surfaces by ensuring they are clean, dry and free of dust, grease and loose particles. Cut the cartridge nozzle to the desired bead size and fit into a standard caulking gun. Apply a continuous bead of adhesive to one of the mating surfaces and press parts together within the initial tack time. For vertical or overhead joints, provide temporary support until the adhesive achieves sufficient handling strength. Allow the adhesive to cure fully according to temperature and humidity conditions before applying loads.

Usage recommendations

For optimal adhesion, roughen smooth or non-porous substrates slightly and test compatibility on plastics or coated surfaces before full application. Avoid use on surfaces continuously immersed in water or on materials that bleed plasticizers unless compatibility is confirmed. Store cartridges in a cool, dry place and follow local safety guidance for ventilation and protective equipment during application.
