Surface Coating / Alfa Chemistry

Customized Nanocoating on Porcelain Substrate


Porcelain is a ceramic material manufactured by firing heated ingredients at extremely high temperatures in a kiln. Porcelain is made primarily of the mineral kaolin. Porcelain has a wide range of engineering applications, particularly in ceramic engineering. Porcelain is a strong high-voltage insulator, particularly in outdoor applications. Porcelain can be utilized for construction in the shape of tiles or huge rectangular panels. Glazed porcelain has been utilized for personal hygiene because of its longevity, lack of corrosion, and impermeability.

Porcelain with a functional surface has a variety of unique qualities that can be used in a variety of applications. Alfa Chemistry provides porcelain substrates with unique functionalized surface coating services. You can change the surface properties of practically any product made of porcelain materials using our wide and simple surface modification procedures. Working with us guarantees that you will be able to modify the surface of your product with ease!

Extensive Surface Modification Technology Options

Alfa Chemistry provides a comprehensive range of coating processes for glass and ceramic surfaces to its customers. We can offer porcelain surfaces a range of unique surface qualities by functionalizing them. The following are some of our surface modification technology possibilities, however they are not exhaustive. For more technical details, please contact us.

  • Surface Waterproof Coating Technology - We can add hydrophobic and oleophobic properties to the surface of porcelain substrates, making them highly water and oil resistant and effectively impervious to all liquids.
  • Hydrophilic Coating Technology - We can make the porcelain surface very hydrophilic by functionalizing it, allowing water to absorb and travel through it readily.

Chemically stable, optically transparent, and long-lasting nanoscale coatings are shown above.

Case 1: Porous surface coating to inhibit microbial adhesion

Porous surface (SLIPS) coatings have a lot of potential for preventing biofilms caused by algae and bacteria. Alfa Chemistry uses a less difficult approach to create smooth lubricant-infused porous surface SLIPS coatings on fluorosilylated porcelain substrates to inhibit biofilm adhesion.

We looked into how effective SLIPS surfaces are in preventing biofilm adhesion to porcelain substrates. First, we took advantage of porcelain's intrinsic porosity, which was enhanced by piranha solution etching. Second, we chose a lubricant made of perfluoropolyether (PFPE). Furthermore, due to their low surface energy and immiscibility with most liquids, PFPE lubricants can offer hydrophobicity and oleophobicity to substrates, making them extensively repelling. The incorporation of piranha to activate and hydroxylate the ceramic substrate surface to achieve a higher degree of silylation is the method's novelty.

The key component to the SLIPS coating's ability to hinder microbial adhesion and colony growth is its liquid-like surface. Toxicity tests revealed that the lubricant's toxicity was unimportant. The effect of the degree of algal accumulation on SLIPS coatings was also examined. According to the findings, SLIPS coating can inhibit the settling of algal biofilms by 90%. When there are germs present, this ratio drops to 75%.
