Photochromic pigments are a special type of pigment whose color changing principle is based on the chemical structure of photosensitive molecules and the action of light. After irradiated by sunlight/ultraviolet rays, it can absorb the energy of sunlight/ultraviolet rays and produce the change of molecular structure, which leads to the change of absorbing wavelength and..

In today’s world, personal protective equipment (PPE) has become an essential requirement in various industries. PPE, such as safety glasses, helmets, and gloves, are designed to protect workers from potential hazards like chemicals, flying debris, and extreme temperatures. While selecting the appropriate protective gear is crucial, it is equally important to choose the right type..

Photochromic pigments are a fascinating class of materials that change color when exposed to light, often in response to UV radiation. These pigments are widely used in various industries for their unique optical properties and ability to change the color of an object, making them a popular choice for products like eyeglasses, toys, and security..

Photochromic pigments are also called light sensitive pigments, uv reactive pigment powder, uv sunlight activated pigment, etc. The principle of color change is to absorb the ultraviolet light source with a specific wavelength and change the powder to a certain wavelength. The energy of the light source produces a color change to blue. When the..
