Origin And Key Applications of Room Temperature Fluorine-free Waterproofing Agents

In recent years, fluorine-free waterproofing has become increasingly popular in the industry. However, those who have actually used it know that most water-based fluorine-free waterproofing agents require drying temperatures of 150℃ or even higher to achieve the desired effect. Insufficient temperature results in poor film formation and a significant drop in water repellency. This high-temperature process also presents numerous challenges in terms of energy consumption, equipment, and fabric compatibility.

While traditional solvent-based fluorine-free waterproofing agents are easy to form films, their flammability, strong odor, and health risks prevent large-scale production, thus hindering widespread adoption.

Because of these limitations, Sylic's R&D team turned their attention back to the film-forming mechanism, developing a new system that can form waterproof films at low temperatures or even room temperature. Simply put, this involves introducing a low-temperature film-forming monomer into the fluorine-free waterproofing system, combined with our proprietary polymerization process, allowing the polymer to form a film on the fabric surface without requiring high temperatures. This means that many fabrics that previously required high temperatures can now achieve effective results at room temperature or even low temperatures.

Several key applicable process scenarios:

1. Dyeing and finishing plant liquid coating process

Suitable for various fluorine-free waterproof finishing processes, especially for materials with poor heat resistance such as SMS and paper.

Fabrics that previously required drying at 170℃ can now be dried at temperatures below 130℃, resulting in significant energy savings and emission reductions.

2. Spray-on waterproofing

Suitable for spray coating applications on garments, shoe materials, webbing, etc.

The biggest advantage of this system is that it dries naturally at room temperature, contains no solvents, and has no odor. It can directly replace solvent-based systems and is currently a highly sought-after environmentally friendly solution by brands.

3. Washing plant finishing

For example, finishing garments, cut pieces, and shoe materials, as well as waterproofing treatments for household cleaning products.

The process is simplified and easier for operators to learn.

Two Product Options and Their Differences

Room temperature fluorine-free waterproofing agents are available in FU5234 and FU5234S for various applications.
