Siser Chroma Sun Photochromic | Cut-Only Heat Transfer Vinyl

Siser Chroma Sun Photochromic | Cut-Only Heat Transfer Vinyl Overview Siser Chroma Sun heat transfer vinyl is a photochromic material that reacts to UV light. The material appears white before exposure and changes colour when ultraviolet light reaches the surface. Current options change from White to Blue or White to Pink. UV-Responsive Colour Change Chroma Sun uses photochromic technology to create a dynamic colour-changing effect. The visual transformation occurs when the material is exposed to UV light. This makes it ideal for garment graphics designed to react to outdoor conditions. White Indoors, Coloured in UV Light The material begins with a clean white appearance before UV exposure. Under suitable ultraviolet light, the colour develops into the selected Blue or Pink effect. The result adds a changing visual feature to decorative garment graphics. 90 Micron Face Film Siser Chroma Sun uses a 90 micron face film. The construction is suited to professional cut-only garment decoration. It also supports straightforward cutting, weeding and heat application. White to Blue and White to Pink The current live range contains two colour-changing options. White to Blue develops a blue appearance under UV exposure. White to Pink develops a pink appearance under UV exposure. Adhesive Polyester Liner Chroma Sun is supplied on an adhesive polyester liner.
