The polyurethane dispersion (PUD) must possess an Appropriate solid content to ensure efficient film formation while minimizing curing energy consumption. It requires high mechanical performance, including tensile strength ≥15 MPaand elongation ≥400%, with adjustable hardness or modulus via soft/hard segment tuning. The dispersion enables uniform foam structures using nitrogen or azodicarbonamide foaming agents, coupled with silicone/fluorocarbon stabilizers to maintain foam stability. Process compatibility demands viscosity control and gradient curing to prevent defects.

Product Introduction

WL-PU215A is an aliphatic polyurethane waterborne dispersion with low viscosity, high elasticity, and good resistance to yellowing, suitable as the main resin for mechanical foaming coatings.

Specification

Properties

• The film is relatively soft, has a good hand feel, and the surface is not sticky;
• Excellent resistance to yellowing, up to level 5;
• Good elasticity, elongation greater than 800%, rapid rebound, good rebound;
• It can be directly used for mechanical foaming, and the foam is stable and delicate;
• Excellent resistance to twists and turns;
• Good dispersibility of pigments and fillers;
• Good compatibility with other resins.

Application

This product is ideal for applications in apparel jackets, bags, shoe uppers, and similar items. It serves as the primary resin for textile printing inks and can be flexibly blended with acrylic resins to meet specific formulation needs.

Furthermore, by utilizing our extensive technical knowledge, we deliver customized solutions and adapt formulations to strictly adhere to defined quality criteria and performance objectives, guaranteeing superior compatibility and operational effectiveness across various applications.

Storage Condition

Store this formulation in an airtight container at ‌5°C to 40°C (41°F–104°F)‌. Under proper storage, the product retains chemical stability and performance integrity for ‌≥6 months‌. Post-opening, expedited usage is critical: The evaporation of water will cause the product to form a film that cannot be further dispersed, which is irreversible

Packaging

Package: 125 KG/Barrel
