Non-fluorinated durable water repellent and stain resistant coating

Fluorinated materials have been broadly used in the industry of water repellent and stain resistance. Because fluorinated materials have low surface tension, and the coatings could easily be manufactured as water-repellent and stain-resistant, fluorinated materials dominate the market for breathable waterproof textiles. However, these materials had substantial health hazards because of the toxicity of fluorinated materials. Moreover, many governments also regulate fluorinated materials for health reasons. As a result, non-fluorinated materials replacing fluorinated materials have become a trend in the industry. As a result, many companies are actively looking for solutions for non-fluorinated water-repellent and stain-resistant materials. This literature review will give a comprehensive understanding of water-repellent properties, materials surfaces, and stain-resistance properties, materials, and surfaces.Moreover, this review would also include reviews of natural water repellent and stain repellent. Furthermore, this review will also talk about the theories behind the materials. Additionally, the fabrication process limitation and future outlook will be discussed in this review.
