Release time:2026-05-19


Environmental friendliness, adhesion, water resistance and lamination strength have long been core pain points in flexible packaging, film printing and heat bonding industries. Leveraging years of R&D strength in water-based polyurethane, Guangdong KDD Functional Materials Co., Ltd. launches PU2501 water-based PVC heat-bonding polyurethane resin. Featuring one-component eco-friendly formula, excellent compatibility with pigments and colorants, superior PVC adhesion and outstanding heat bonding performance, it delivers stable and efficient green solutions for the industry.
 

Core Product Advantages

 

One-component water-based system, easy operation & eco-friendly

 

Using water as dispersion medium, it features low VOC content and simple application. Ready-to-use without complex proportioning, compatible with high-speed printing and automatic coating, greatly boosting production efficiency and reducing safety hazards.

 

Excellent color matching performance for vivid printing effect

 

Stable dispersion for pigments and colorants with uniform color development and great compatibility. Suitable for gravure and various water-based ink processes, presenting full-color printed products free from delamination and coarsening reversion.

 

Strong adhesion & superior water resistance for reliable quality

 

Boasts outstanding adhesion to PVC and PET films and remarkable water resistance of dry film. It resists humid environments and daily water immersion, preventing whitening and peeling of coating and ink layers.

 

High heat bonding strength for firm lamination

 

High thermal bonding activity ensures tight lamination without glue separation or delamination, meeting high-temperature hot pressing requirements for packaging films, label films, decorative films, etc.

 

Stable physical & chemical indicators for worry-free mass production

 

Milky white translucent liquid; solid content: 39%; viscosity below 500cps at 25℃; pH value: 7-9. It enjoys stable storage performance and is fully applicable to large-scale continuous production.

 

Full Coverage of Downstream Applications & Multi-scenario Adaptation
