HYDROCHROMIC FILM REACTS TO WATER
PRODUCT INFORMATION
SFXC Hydrochromic film is a moisture-sensitive, water-reactive material that reduces in opacity when exposed to water and certain liquids. This effect is reversible, transitioning from white (dry) to translucent when activated.
This behaviour allows images, colours, or text beneath the film to be hidden when dry and revealed when wet, creating a clear and visually engaging wet-reveal effect.
CHOOSING THE RIGHT SHEET
For creative, educational, and interactive applications:
This hydrochromic film sheet provides a flexible, easy-to-use solution for visual wet-reveal and water-reactive effects.
For precision thermal mapping and controlled performance:
Our SFXC Precision-Calibrated Liquid Crystal Sheets offer defined temperature ranges, repeatable results, and engineered Colour Play behaviour for engineering, laboratory, and R&D use.
APPLICATION
This adhesive-backed hydrochromic film provides a simple and effective way to apply a water-reactive effect to a wide range of surfaces without the need for spray equipment or coatings. To apply, remove the backing liner and position the film onto a clean surface.
The material is flexible and can be cut to size using scissors, a craft knife, or a guillotine, making it suitable for prototyping, design work, printed materials, demonstrations, and production applications.
Hydrochromic materials are used across a wide range of applications, including drinks labels, packaging, fashion, art installations, printed materials, wet-and-reveal promotions, moisture indicators, and educational demonstrations.
As a smart material, hydrochromic film is also widely used in schools, colleges, and museums as part of learning programmes covering responsive materials and surface interaction.
ADDITIONAL USES
Beyond traditional applications, hydrochromic film is increasingly used in interactive and experiencedriven projects where a wateractivated reveal adds surprise, engagement, or functional value. Examples include:
- Interactive signage and displays: Reveal graphics, instructions, or branding when sprayed with water or exposed to rain.
- Escape rooms and puzzle design
