Fluorine-free waterproofing agents are increasingly used in the fields of textiles, leather, etc. and shoe materials.

Fluorine-free waterproofing agent is a new type of environmental protection product. Compared with traditional fluorine-containing waterproofing agent, it has better environmental protection performance, does not contain fluorine compounds, has less impact on the environment, and can better protect the earth.

Ecological environment. Fluorine-free waterproofing agent has good biodegradability, is not easy to deposit in living organisms, and has little impact on the human body and living organisms. Therefore, it has great applications in the field with high environmental protection requirements.

Advantage. In addition, fluorine-free waterproofing agents are safe for the human body and the environment, and will not cause irritation or allergic reactions to the human body. Therefore, it is increasingly used in textiles, leather and other fields with direct contact with the human body.

However, fluorine-free waterproofing agents also have some disadvantages. Compared with fluorine-containing waterproofing agents, the waterproof performance of fluorine-free waterproofing agents is relatively weak, which can only give the fabric waterproof performance, but not oil-proof performance.

And the durability is poor. After a period of use, its waterproof effect may gradually weaken. In addition, the production cost of fluorine-free waterproofing agent is relatively high, resulting in a relatively high price, which makes it cost-sensitive.

It is difficult to promote and apply on a large scale in the field.

In terms of technological development, there are many types of fluorine-free waterproofing agents, mainly including silicone fluorine-free waterproofing agents, fluorine-free water-based polyurethane waterproofing agents, polyacrylate fluorine-free water-repellents, and modified amino resins.

Waterproofing agent, etc. For example, silicone fluorine-free waterproofing agents are copolymerized with organic polymer emulsion and reactive silicone emulsion, and the treated textiles have good hydrophobicity and do not affect the textiles.

Breathability. As a non-toxic and pollution-free material, water-based polyurethane has also attracted much attention and has become the best material for high-end fabric coating agents.

In general, fluorine-free waterproofing agents are valued for their environmental protection characteristics, but they also need to overcome their performance and cost challenges to achieve a wider range of applications.
