Phytic acid based novel optically transparent intumescent fire-retardant coating for protection of combustible substrates with retention of aesthetic appearance

Phytic acid-based novel optically transparent intumescent fire-retardant coating is a new and exciting development in the field of fire safety. It holds the potential to revolutionize the way we protect combustible substrates, not only by enhancing fire resistance but also by maintaining their aesthetic appeal. Here’s a breakdown of this innovative coating:

Key components:

  • Phytic acid: This naturally occurring organic acid acts as a phosphorus source, a crucial element in intumescent fire retardancy.
  • Intumescent system: This combination of ingredients, often including a carbon source and blowing agent, expands upon exposure to heat, forming an insulating char layer that protects the underlying substrate.
  • Transparency modifiers: These carefully chosen additives ensure the coating remains optically clear, allowing light to pass through and preserving the visual appearance of the substrate.


  • Enhanced fire resistance: The intumescent char layer formed during a fire slows down the spread of flames and heat, providing precious time for evacuation and firefighting.
  • Optically transparent: Unlike traditional fire-retardant coatings, which can be opaque or heavily pigmented, this novel coating maintains the visual appeal of the substrate. This is particularly beneficial for applications where aesthetics are important, such as architectural elements, display screens, and decorative finishes.
  • Environmentally friendly: Phytic acid is a naturally occurring and biodegradable compound, making this coating a more sustainable option than some traditional fire retardants.
  • Durable: The coating is designed to be long-lasting and withstand weathering and wear and tear.


  • Building elements: Walls, ceilings, doors, windows, and other architectural components made from wood, plastic, or other combustible materials.
  • Transportation: Interiors of airplanes, trains, and buses.
  • Electronic devices: Display screens, circuit boards, and other sensitive components.
  • Decorative finishes: Furniture, artwork, and other decorative items.

Current research:

While this technology is promising, research is ongoing to further optimize its performance. Areas of focus include:

  • Improving transparency: Increasing the clarity of the coating while maintaining its fire-retardant properties.
  • Fine-tuning the intumescent system: Enhancing the char formation and insulation capabilities for even better fire protection.
  • Expanding compatibility: Developing formulations that adhere to a wider range of substrates.

Overall, phytic acid-based novel optically transparent intumescent fire-retardant coating is a significant advancement in fire safety technology. It offers the potential to save lives, protect property, and maintain the aesthetic beauty of our built environment.
