Photochromic Pigment Purple Manufacturer,Supplier and Exporter in India
Product Code : EL-MTP-11675
The photochromic pigment purple is a light-activated smart material used for demonstrating reversible colour change under sunlight or ultraviolet light. Supplied as 3g in a plastic syringe, it helps staff and students observe how photochromic dye microcapsules respond visibly to changing light exposure.
Product Description
Photochromic Pigment Purple from School Equipments India is designed for practical lessons on materials and their properties. The pigment normally has a pale, off-white appearance away from sunlight or UV light and changes to a bright purple colour when exposed to activating light.
The active photochromic dye is contained in micron-size microcapsules dispersed in water, giving the pigment a thick cream-like consistency. When mixed with a suitable binder, such as an acrylic base, it can be applied to surfaces for classroom samples, UV-warning demonstrations, smart graphics, packaging examples and garment-design activities.
Key Features
- Verified 3g supply: Supplied in a plastic syringe for controlled classroom and laboratory use.
- Light activation: Changes colour when exposed to sunlight or ultraviolet light.
- Purple colour response: Develops a bright purple colour under activating light.
- Reversible behaviour: Returns to a pale colour when removed from sunlight or UV light.
- Smart material example: Demonstrates stimulus-responsive material behaviour clearly.
- Microcapsule formulation: Uses photochromic dye in micron-size microcapsules dispersed in water.
- Flexible application: Suitable for brush painting, block printing, stencilling and screen-printing demonstrations.

How to Use the Photochromic Pigment Purple
- Place a small amount of pigment on a clean mixing surface.
- Mix the pigment with a suitable clear binder, such as an acrylic base, when an applied sample is required.
- Start with a small trial mixture; a 50:50 pigment-to-binder mix is a practical starting point.
- Apply the mixture by brush painting, block printing, stencilling or screen printing.
- Allow the prepared sample to dry according to the binder instructions.
- Expose the sample to sunlight or UV light and observe the purple colour change.
- Move the sample away from sunlight or UV light and observe the return to a pale colour.
Safety and handling: Use under staff supervision. Avoid ingestion, eye contact and unnecessary skin contact. Follow the safety instructions for any binder, medium or UV light source used with the pigment.
Care & Maintenance
- Keep the syringe sealed when not in use to reduce drying and contamination.
- Store away from direct sunlight, UV lamps and excessive heat.
- Test the pigment-to-binder ratio on a small sample before preparing a final demonstration piece.
- Clean brushes, screens and tools promptly according to the binder or medium being used.

Frequently Asked Questions
```
What is Photochromic Pigment Purple used for?
Photochromic Pigment Purple is used to demonstrate reversible colour change under sunlight or UV light. It is suitable for smart-material lessons, STEM activities and applied surface demonstrations.
What colour does Photochromic Pigment Purple change to?
The pigment normally appears pale or off-white away from sunlight or UV light. Under sunlight or UV light, it changes to a bright purple colour.
How much pigment is supplied?
The product is supplied as 3g of Photochromic Pigment Purple in a plastic syringe.
Can it be mixed with acrylic binder?
Yes. The official product information states that the pigment can be mixed with a binder such as an acrylic base and applied to surfaces.
Is the colour change permanent?
No. The colour change is reversible. The pigment returns to its pale colour when it is moved away from sunlight or UV light.
Can students use this pigment in school?
Yes. The product is listed for staff and student use. It should still be handled under supervision, especially when mixed with binders or used near UV light sources.
