Solvent Free Two Component Polyurethane Adhesive High Strength

Product Description:

The Polyurethane Adhesive is a high-performance solvent-free lamination adhesive designed for plastic bonding, soft packaging, and food packaging applications. Its advanced formulation delivers excellent adhesion, durability, and flexibility, making it a reliable choice for demanding packaging lamination needs.

A key feature is its Component B packaging options: 20 Kg/drum and 210 Kg/drum, catering to different production scales for cost-effectiveness. When mixed with Component A (25 Kg/220 Kg drums) at the recommended ratio, it forms a stable adhesive system with consistent performance.

This adhesive appears as a pale yellow transparent liquid, ensuring purity and quality. Its clarity avoids affecting the visual appeal of final packaging products, which is crucial for food and soft packaging industries.

The recommended mixing ratio is A:100 to B:65—adhering to this ratio is critical for optimal curing, bond strength, and flexibility, ensuring the adhesive withstands processing stresses and environmental exposure.

For best results, apply the adhesive at a coating temperature of 45–50℃. This range ensures smooth flow, uniform coating, and strong bonding, reducing defects like bubbles or incomplete lamination.

It excels in bonding common packaging films (polyethylene, polypropylene, etc.), providing the flexibility and strength needed for soft packaging. It also meets food packaging safety standards, ensuring no contamination of food products.

In summary, this solvent-free polyurethane adhesive is a versatile, reliable solution for plastic bonding, soft packaging, and food packaging. Its balanced formulation, flexible packaging, and clear application guidelines make it ideal for modern packaging manufacturing, delivering superior performance and safety.
