Aliphatic Polyurethane Water Based Dispersion For Thermal Transfer Printing Elastic Layer

The primary resin characteristics of polyurethane dispersions (PUDs) used in heat-transfer printing pastes for elastic layers or waterproof fabrics include:

• High elasticity and flexibility‌, enabled by their molecular structure to withstand substrate deformation;
• ‌Water-based eco-friendliness‌, free of solvents, formaldehyde, and APEO, meeting stringent environmental standards;
• ‌Strong adhesion and wash resistance‌, forming dense, crosslinked films that resist water penetration and mechanical wear;
• ‌Thermal stability‌ to maintain integrity during heat pressing while enabling low-temperature curing to protect heat-sensitive fabrics;
• ‌Inherent anti-blocking properties‌, reducing surface tackiness to prevent adhesion during transfer processes;
• ‌Compatibility with additives‌ for viscosity control and process adaptability. PUDs outperform acrylics in elasticity and wash durability, making them ideal for stretchable textiles and waterproof applications.

Product Introduction

WL-PU209 is an aliphatic polyurethane water-based dispersion with low viscosity, high elasticity, and good resistance to yellowing. It is suitable as the main resin for printing adhesives of heat transfer elastic layers or waterproof fabrics.

Specification

Properties

l Soft film formation and good hand feel;

l Excellent resistance to yellowing, up to level 5;

l Good elasticity, high elongation, elongation greater than 800%;

l Good washing fastness;

l Good dispersibility of titanium dioxide, able to quickly wet and disperse titanium dioxide;

l The semi dry alcohol soluble ink has excellent adhesion;

l Very good adhesion to waterproof nylon cloth

Application

WL-PU209 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.

Additionally, leveraging our deep technical expertise, we provide tailored solutions and customize formulations to align with precise quality standards and performance targets, ensuring optimal compatibility and functionality for diverse end uses.

Storage Condition

This product should be stored in a sealed manner within the temperature range of 5 ℃ to 40 ℃. Under these conditions, the product can maintain stable performance for more than 6 months. The evaporation of water causes the film to no longer disperse. Please use it as soon as possible after opening.
