Introduction
Waterborne polyurethane dispersion(PUD) have emerged as pivotal materials in modern industrial production, favored for their environmental friendliness and versatile performance. Among them, the waterborne PUD discussed herein stands out with its exceptional film-forming elasticity, reliable adhesion, and broad applicability, making it a preferred choice across multiple fields.
Core Performance Advantages
This waterborne PUD is characterized by outstanding flexibility and elastic performance, which endow the formed film with excellent resilience—enabling it to recover quickly after being subjected to external forces without permanent deformation. Meanwhile, it exhibits strong adhesion on a variety of substrates, ensuring stable bonding and long-term performance retention in different application scenarios. The product appears as a bluish liquid, with a solid content of 40±1%, a pH value ranging from 7.0 to 9.0 (measured at 25°C), and a viscosity of less than 800 mPa·s (tested by Brookfield at 25°C), presenting favorable processing properties for subsequent production operations.
Versatile Application Fields
Thanks to its comprehensive performance, this waterborne PUD has found wide application in multiple key fields. In the paper plastic-substitute sector, it serves as an ideal material for manufacturing environmentally friendly paper-based products that replace traditional plastics, contributing to reduced plastic pollution. Additionally, it performs excellently in the leather industry, where it enhances the softness and durability of leather products. It is also suitable for the textile field, providing functional modifications to textiles to improve their comfort and performance. Its versatility allows it to meet the diverse requirements of different industrial sectors.
Storage and Handling Guidelines
To maintain the product's stable performance, proper storage and handling are essential. When stored in intact original packaging, the product remains stable for 6 months at 20°C after delivery. The recommended storage temperature range is 5°C to 30°C. Freezing or exposure to temperatures exceeding 30°C may adversely affect the product's viscosity and average particle size, potentially leading to sedimentation or coagulation. Moreover, contamination by bacteria, fungi, or algae can cause irreversible damage to the product, so strict hygiene control during storage and use is necessary.
Conclusion
This waterborne polyurethane dispersion excels with its excellent film formation elasticity, reliable adhesion, and favorable physical and chemical properties. Its wide applicability across paper plastic-substitute, leather, textile, and other fields highlights its strong practical value in industrial production. By adhering to the recommended storage and handling requirements, users can ensure the product maintains its optimal performance, making it a trustworthy and efficient material choice for enterprises pursuing high-quality and environmentally friendly production solutions.
