Wood Adhesive Technicqll polyurethane D4 250 ml (C2-R123)

Technicqll polyurethane D4 wood adhesive in a 250 ml cartridge is a moisture-resistant structural glue designed for bonding solid wood and wood-based materials. Classified as D4, this polyurethane adhesive forms strong, durable joints that resist high humidity and occasional water exposure, making it suitable for demanding indoor and outdoor woodworking tasks such as furniture assembly, joinery, and repair. The cartridge format supports application with a standard caulking gun for controlled dispensing and precise bead placement.

Advantages

This polyurethane wood adhesive offers long-lasting, water-resistant bonds and high initial tack for secure assembly. It cures to a rigid, gap-filling joint that compensates for minor surface irregularities and wood movement. The cartridge packaging ensures convenient application, reduced waste, and compatibility with common dispenser guns. Suitable for use on various wood types and engineered wood products, the adhesive provides reliable performance in conditions with elevated humidity.

Suitable for

• Furniture assembly and repair
• Carpentry and timber joinery
• Bonding solid wood, plywood and MDF
• Interior and exterior applications with occasional moisture exposure

Key specifications

• Cartridge volume: 250 ml
• Adhesive type: polyurethane
• Classification: moisture-resistant D4 performance
• Curing: moisture-activated polymerization
• Bond characteristics: structural strength, gap-filling, high initial tack
• Application method: standard caulking gun

How to use

Prepare bonding surfaces by cleaning off dust, grease and loose particles; surfaces should be fit for contact but can be slightly damp to support curing. Cut the cartridge nozzle to the required bead size and apply with a standard caulking gun, laying a continuous bead to one of the mating surfaces. Clamp or press assembled parts together immediately to ensure contact and alignment; maintain clamping pressure until the adhesive has cured sufficiently for handling. Typical handling strength is achieved within hours depending on temperature and humidity; full cure occurs over a longer period under recommended conditions.

Usage recommendations

Store cartridges in a cool, dry place and avoid freezing. Use personal protective equipment such as gloves and eye protection when dispensing. Ensure adequate ventilation during application. Follow recommended clamp times and test on a small area if bonding unfamiliar substrates or finishes.
