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.
