Waterproof Liquid Polyurethane Adhesive For Plastic Two Part Adhesive

This two-component solvent-free polyurethane adhesive is engineered for outstanding bonding performance and long-term durability in film lamination. Built with advanced polyurethane formulation, it delivers reliable adhesion and excellent appearance, making it a preferred solution for high-barrier flexible packaging.

One of the core advantages of this adhesive is its superior leveling property. It ensures smooth, uniform coating and ideal visual performance especially on high-barrier film structures, supporting high-quality lamination for premium packaging products.

This adhesive also features excellent heat resistance, enabling reliable performance in spout pouches, gear heat sealing and other heat-resistant applications under proper processing conditions. It maintains stable bonding strength and appearance even in thermal processing scenarios.

The two-component system (Part A and Part B) is designed for stable processing and easy operation. At 25℃, Part A features a viscosity of 1200–2400 mPa·s and density of 1.21 g/cm³; Part B has a viscosity of 1600–2800 mPa·s and density of 1.16 g/cm³. The recommended mixing ratio is 100:65 (A:B), with suggested coating temperature of 45–50℃.

It shows strong compatibility with common lamination substrates including PE, CPP, BOPP, PET and PA films. The adhesive works well with 2-in-1 and 3-in-1 solvent-free laminators, supporting stable mass production.

This product is supplied in standard industrial packages: Part A in 25 kg and 220 kg drums; Part B in 20 kg and 210 kg drums, suitable for small-batch trials and large-scale industrial production.

It should be stored sealed in a cool and dry environment at 15–30℃, with a shelf life of 12 months in original unopened packaging. To ensure optimal performance, preheat the adhesive at 40–45℃ before use and avoid mixing with other adhesive types.

In summary, this two-component solvent-free polyurethane adhesive combines excellent leveling, high heat resistance, stable processing performance and broad equipment compatibility. It is specially developed for high-barrier film lamination and flexible packaging, providing consistent, durable bonding performance for packaging manufacturers pursuing high quality and reliability.

Whether you produce high-barrier composite films, spout pouches or other flexible packaging structures, this two-component solvent-free polyurethane adhesive offers stable performance, easy operation and trusted durability to meet demanding industrial lamination requirements.
