Advantages
Excellent bonding strength for diverse materials such as wood, metal, and composite panels.
Outstanding flexibility and impact resistance, maintaining performance under stress or vibration.
Superior weather, heat, and moisture resistance for long-term durability.
High solid content with slight foaming ensures gap filling and stability.
Room-temperature or heat curing, suitable for multiple production conditions.
Classification
Polyurethane adhesives are available in:
One-component reactive PU — moisture-curing type, simple to use, ideal for wood and panel bonding.
Two-component PU — chemically curing system with high solid content, designed for industrial applications requiring maximum strength and heat resistance.
PUR hot melt — reactive melt adhesive that combines strong bonding with fast setting.
Applications
Polyurethane adhesives are widely used in:
Flooring — bonding wood, composite, or multi-layer parquet with excellent dimensional stability and no deformation.
Wood Jointing — ensuring strong structural joints in furniture and building components.
Wooden Doors — ideal for composite door panels, metal-wood or UV-painted board lamination.
Composite Panels — bonding stone, calcium silicate board, steel, or iron plates to wood materials.
Decorative Boards — suitable for UV-painted or veneer panels that require superior bonding and durability.
FAQs
Q1: What’s the difference between one-component and two-component polyurethane adhesives?
A1: One-component PU cures with moisture in the air and is easy to apply, while two-component PU cures by chemical reaction, providing higher bonding strength, heat resistance, and stability.
Q2: Can polyurethane adhesives be used on metal and stone materials?
A2: Yes. PU adhesives show excellent adhesion to metal, stone, and wood, making them ideal for composite panels or hybrid structural applications.
Q3: Are polyurethane adhesives suitable for high-temperature or outdoor environments?
A3: Absolutely. Polyurethane adhesives offer excellent weather, UV, and heat resistance, ensuring long-term performance for outdoor and architectural use.
