What is PU glue?

PU glue refers to Polyurethane glue, which is a type of adhesive that belongs to the family of polyurethane-based adhesives. PU glue is known for its strong bonding properties and versatility. PU glue is commonly used in various applications due to its ability to bond a wide range of materials, including wood, metals, plastics and more.

What are characteristics and features of PU glue?

1. Versatility

PU glue is suitable for bonding different types of materials, making it a versatile adhesive for various applications.

2. Strong Bonding Strength

PU glue is known for providing strong and durable bonds. It often creates bonds that are resistant to heat, water and various environmental conditions.

3. Flexibility

PU glue exhibit flexibility in their cured state, making them suitable for applications where a degree of flexibility in the bond is desirable.

4. Moisture Curing

Many PU glues are moisture-curing, meaning they react with moisture in the air or on the material surfaces to cure and form a bond. This can be advantageous in certain bonding applications.

5. Water Resistance

PU glue generally has good water resistance, making them suitable for both indoor and outdoor applications.

6. Gap-Filling Properties

PU glue often has good gap-filling properties. They can bond eneven or irregular surfaces effectively.

7. Application Methods

PU glue is available in various forms, including liquids, gels and foams. This allows for different application methods depending on the specific needs of the project.

8. Common Uses

PU glue is commonly used in woodworking for bonding ffurniture, cabinets and other wooden structures. It is also used in construction, automotive applications and general bonding tasks.

9. Curing Time

The curing time for PU glue can vary depending on the specific formulation and product. Some PU glues may have relatively longer curing times compared to certain fast-setting adhesives.
