Description
Want to try Thermochromic products without breaking the bank? SFXC's handy pack of colour to colour acrylic inks change from one colour to another when heated to 28°C/82.4F.
These are high quality, water-based, BPA free acrylic inks which change colour when touched with your warm hands! Apply onto fabric, textiles and paper or board.
Our lovely customer Elizabeth can be seen in the picture using a paintbrush to apply these lovely colours onto a cotton T-shirt, painstaking work, and well worth the result. Thank you for sharing this with us Elizabeth!
This pack contains 4 vibrant colour to colour inks, available as 25ml (samples) or 250ml bottles each of:
Blue to Neon Green
Purple to Neon Magenta
Green to Neon Yellow
Orange to Neon Yellow
The 25ml sizes (which are samples) come in a handy re-sealable foil pouch.
Use screen printing method or a thin foam roller when applying this ink. This way, the product will distribute more evenly, especially onto paper and card. Although you can use a brush, the result will be far preferable when using a paint roller.
Coverage is 50ml per square meter per coat.
Once applied to your chosen surface, use a heating device such as a hairdryer, to cure the product so it can last longer.
These inks are great for making colour changing designs or promotional items!
Store this product in a cool, dry place. Do not expose this paint to UV/sunlight for an extended period. Otherwise the ink will degrade and its Thermochromic properties will no longer work as intended.
