Assembly Adhesive Technicqll Colos Force R-438 290 ml – high-strength construction adhesive

Technicqll Colos Force R-438 290 ml is a high-strength assembly adhesive designed for demanding construction and installation tasks. The product is formulated to bond a wide range of common building materials including metals, wood, ceramics and many plastics, delivering a durable adhesive layer suitable for mounting profiles, panels, skirting and stair components. The cartridge format and 290 ml capacity make it compatible with standard assembly pneumatic or manual guns for controlled application.

Advantages

Colos Force R-438 provides a high initial tack and strong final bond strength across diverse substrates, reducing the need for mechanical fasteners in many applications. The adhesive cures to form a resilient joint with good shear resistance and long-term adhesion, offering reliable performance in interior and sheltered exterior installations. Its cartridge packaging allows precise dosing and cleaner application compared with bulk adhesives.

Suitable for

• Mounting decorative and protective panels on walls and ceilings
• Bonding skirting boards and profiles where nail or screw fixing is impractical
• Securing stair nosing and wooden components
• Joining metal trims and brackets to building substrates
• General assembly and repair of ceramic tiles, some plastics and composite materials

When it may not be suitable

The adhesive is intended for use on many common substrates but may not be suitable for continuous underwater exposure or applications requiring certified structural load-bearing connections unless specifically tested for that use. Some low-surface-energy plastics and highly flexible materials can be difficult to bond without prior surface preparation or a compatible primer. Always verify compatibility on a small inconspicuous area when in doubt.

Key specifications

• Volume: 290 ml cartridge
• Adhesive type: high-strength assembly adhesive
• Typical substrates: metals, wood, ceramics, many plastics, common building substrates
• Application method: cartridge for manual or pneumatic gun
• Cure behavior: forms a resilient cured bond with good shear resistance

How to use

Ensure surfaces are clean, dry and free of dust, oil or loose particles. Cut the cartridge tip and fit a suitable nozzle, then apply adhesive in a continuous bead to one of the surfaces. Press parts together within the product's open time and secure with temporary supports or clamps if required until the adhesive has developed sufficient strength. Allow full cure time as required by temperature and humidity conditions before placing the bonded assembly into service.

What to consider before purchase

• Confirm substrate compatibility, especially for low-energy plastics or painted surfaces
• Check required joint gap and fit-up; adhesive performance can vary with bond line thickness
• Consider environmental conditions: temperature and humidity affect cure rate
• Verify whether mechanical fastening is still needed for safety-critical or structural applications

Usage recommendations

For best results, roughen smooth surfaces lightly and clean with a suitable solvent where safe to do so. Apply adhesive at room temperature and allow adequate cure time; use temporary supports for heavy components. Store cartridges in a cool, dry place and follow local disposal regulations for empty containers.
