500ml Illbruck PU220 Polyurethane Wood Adhesive - Moisture‑Curing D4‑Class Adhesive

500ml Illbruck PU220 Polyurethane Wood Adhesive is a high‑strength, moisture‑curing D4‑class adhesive designed for structural and non‑structural timber bonding. It provides exceptional adhesion to softwood, hardwood, engineered timber, and many non‑porous construction materials, making it suitable for demanding interior and exterior applications. The single‑component polyurethane formula expands slightly during curing, filling gaps and irregularities to create a permanent, waterproof bond. PU220 is ideal for load‑bearing joints, exterior joinery, laminated timber, and bonding wood to metals, concrete, insulation boards and plastics. Once cured, the adhesive forms a rigid, chemical‑resistant bond with excellent durability under moisture, temperature changes and mechanical stress.

CHARACTERISTICS

• D4 waterproof rating - suitable for exterior and high‑moisture environments.
• Moisture‑curing polyurethane - reacts with ambient moisture for strong, reliable bonding.
• Gap‑filling - slight expansion fills voids and irregular surfaces.
• High bond strength - suitable for structural timber joints.
• Multi‑material adhesion - bonds wood, metal, concrete, insulation boards and plastics.
• Temperature‑ and chemical‑resistant - stable under heat, cold and environmental exposure.
• Fast curing - rapid strength development for efficient installation.

APPLICATION

• Structural timber bonding - beams, frames, laminated elements.
• Exterior joinery - doors, windows, cladding components.
• Wood‑to‑metal or wood‑to‑concrete bonding - mixed‑material assemblies.
• Insulation board fixing - XPS, PIR, EPS and mineral boards.
• Furniture and carpentry - high‑strength interior joints.
