Product type
Laminating PU adhesive is a type of polyurethane adhesive specifically designed for laminating various substrates. It is typically composed of a mixture of polyols and isocyanates, which react to form a strong, flexible bond. This adhesive is known for its excellent adhesion properties, durability, and resistance to moisture and chemicals, making it suitable for a wide range of applications in the manufacturing and construction sectors.
| Base type | Polyurethane |
| Curing method | Moisture curing or heat curing |
| Viscosity | 1000 to 5000 mPa.s |
| Bonding strength | High tensile and shear strength |
| Temperature resistance | Up to 80°C |
When selecting laminating PU adhesive, consider the specific substrates you will be bonding, as compatibility is crucial for optimal performance. Additionally, specify the required curing method based on your production processes, whether moisture or heat curing is preferred. It is also important to discuss the desired bond strength and any environmental resistance requirements, such as moisture or chemical exposure.
