Product Description

  • KEY-216Herun PFAS-free superhydrophobic nanocoating utilizes the sol-gel method to generate an ultrathin nano-organic-inorganic hybrid coating of only 5-15μm. It is a high-tech environmentally friendly coating product that meets environmental standards.

  • It can be applied to various metal surfaces, including high-end consumer electronics, power energy, rail transportation manufacturing, medical facilities, kitchen appliances, textiles, large building glass curtain walls, cultural relic protection, and municipal facilities. It is long-lasting and easy to clean, replacing traditional electrophoretic treatment to achieve high-strength anti-corrosion function. It also provides high wear resistance, scratch resistance, maintains good heat dissipation, enhances the metallic texture, and keeps the metal surface clean and bright forever.

  • The KEY-216Herun series products have gained high recognition in high-end industrial sectors such as automotive manufacturing, rail transportation, and aerospace due to their superior performance, becoming a preferred solution for these industries. This innovative technology and environmentally friendly characteristics have won widespread market acclaim.


Product Features

  • Serves as a primer protective coating for unchromated light metals.

  • Delivers outstanding corrosion resistance and oxidation resistance.

  • Dust-repellent and anti-adhesive properties enable easy cleaning and maintenance with exceptional scratch resistance.

  • Supports surface coloring and personalized decorative designs, achieving rich metallic effects.

  • Meets customers' high-precision requirements for product dimensions across multiple dimensions.

  • Combines high-temperature protection with resistance to sudden temperature changes.

  • Significantly cost-effective, requiring only 1/10th the coating volume per unit area compared to conventional coatings, substantially reducing overall operating costs.
