1、 Floor UV wear-resistant layer

Modern high-performance floor wear-resistant UV coatings typically adopt a multi-layer structure design, with each layer having specific functions, collectively forming a complete protective system. Taking the common SPC stone plastic flooring as an example, its topmost UV wear-resistant layer is the outermost layer of the coating system, which is in direct contact with the usage environment and therefore requires the best surface performance

The UV wear-resistant layer is responsible for providing key properties such as high hardness, high wear resistance, scratch resistance, anti graffiti, and pollution resistance, and is an important parameter for consumers when making purchases. Tech-UV2727 is added to the UV wear-resistant coating by forming a wear-resistant functional layer on the coating surface, providing properties such as scratch resistance, abrasion resistance, stain resistance, and waterproofing

By forming an organic silicon enriched surface on the outermost layer, Tech-UV2727 can maximize its scratch resistant, wear-resistant, stain resistant, and waterproof functions. At the same time, due to its location on the surface of the coating system, it has little impact on the overall mechanical properties of the coating

 

2、 The source of long-term scratch resistance

Tech-UV2727 provides the following advantages for the UV wear-resistant layer of SPC flooring by directional migration towards the liquid gas interface and reactive crosslinking with resin:

●  Strong scratch and wear resistance: The UV coating containing Tech-UV2727 provides a hard protective layer, significantly improving the scratch resistance of the floor. The organic silicon surface layer reduces the friction coefficient and minimizes the cutting effect of sharp objects on the coating

●  Long term stain resistance: The low surface energy organic silicon layer formed by Tech-UV2727 makes it difficult for liquids such as soy sauce, coffee, and vinegar to spread and penetrate on the surface, providing self-cleaning properties similar to the “lotus leaf effect”

●  Improved surface texture: SPC flooring is sometimes criticized for its plastic feel. The surface smoothness provided by Tech-UV2727 can simulate the touch of natural materials, and the UV coating can be designed with different glossiness (high gloss, matte, semi matte) to enhance the high-end feel of the floor

●  Productivity:In the production of SPC flooring, the curing speed of UV coating to some extent affects production efficiency. Tech-UV2727 participates in UV curing reaction without affecting the curing speed, and its anti adhesion properties facilitate rapid stacking and packaging of the floor after curing, improving the efficiency of the production line

●  Environmental Protection and Safety: The Tech-UV2727 is halogen-free, which is in line with the environmental advantages of SPC flooring itself. Especially in overseas export markets, this feature ensures that the product complies with strict environmental regulations for halogen-free (HF) standards in multiple regions

In the field of SPC/PVC flooring, small improvements in surface performance often mean significant product advantages and market acceptance

 

3、 Antibacterial demand

The rapid development of modern high-performance flooring (such as ABA SPC flooring) has led consumers to consider not only the scratch resistance, wear resistance, and durability of the flooring, but also the health and safety of children and the elderly, as well as places with high hygiene requirements such as hospitals, schools, kitchens, and food processing plants. Using coated flooring with Tech-UV2505 makes it easier to maintain surface cleanliness and reduce microbial breeding grounds

Bacteria usually need two key steps to grow on the surface of an object: 1 Initial attachment; 2. Form a biofilm. Tech-UV2505 mainly affects the first step

After adding the UV wear-resistant layer, the organic silicon segments of Tech-UV2505 will migrate to the outermost layer of the coating, forming an ultra-low surface energy interface, making it difficult for bacteria to adhere to the surface from the beginning and easy to clean

●  Create “non stick” properties: This low surface energy surface allows liquids to form high droplet angles, making it difficult for bacteria, microorganisms, and their metabolites (such as proteins and polysaccharides) to stably adhere to the coating

●  Waterproof and easy to clean: Even if there are a small amount of pollutants or microorganisms attached, due to their weak adhesion, they are easier to remove under routine cleaning (such as wiping, water flushing), making it difficult to form stable colonies and biofilms
