PU Adhesives Explained

Polyurethane (PU) adhesives are versatile adhesives that are widely used in various industries due to their strong bonding properties, flexibility, and resistance to environmental factors. Here’s an overview of PU adhesives:

Characteristics:

1. Strong Bonding: provide excellent adhesion to a wide range of substrates, including metals, plastics, glass, wood, ceramics, and composites.
2. Flexibility: They remain flexible after curing, which is beneficial for applications where thermal expansion, contraction, or vibration is present.
3. Moisture Resistance: have good resistance to moisture, making them suitable for outdoor and marine applications.
4. Durability: They exhibit good chemical resistance, UV stability, and long-term durability.
5. Fast or Adjustable Curing Time: are available in formulations with varying curing speeds, from rapid-curing to extended work times.
