Experience the Wonder of Water-Revealed Transformations

Imagine films that magically transform when they come into contact with water. Our hydrochromic technology appears opaque when dry, concealing hidden colours, messages, or designs. With a simple splash or spray of water, the film becomes translucent, revealing the magic beneath. This effect is fully reversible, resetting as the surface dries—ideal for moisture reactive applications across various industries.

Versatile Applications:

  • Interactive Art & Design: Murals and decor that transform in the rain.
  • Promotional Materials: Water-activated stickers, coasters, and interactive business cards.
  • Educational Tools: Engaging science experiments and visual aids for the water cycle.
  • Security & Safety: Water-sensitive markings and "Slippery When Wet" warnings.

Self-Adhesive Options Available

Many of our hydrochromic films are available with a pressure-sensitive adhesive backing for easy application to paper, plastic, metal, and glass.
