Thermochromic dye causes the change of color by the heat-induced chemical structure change. Since it is very sensitive to the external environment, it is made as a microcapsule-type product for protection, increasing its repetitive durability.
Chameleon T Series features the change of color into colorless by the increase of a specific active temperature.
Bichrom T Series features the change of color into another color by the structural change in specific conditions.
Manufacturing temperatures: 0~70°C
Note: Since thermochromic dye products come in 2~5㎛, the outer wall of capsule is damaged if they go through a milling machine or high-speed disperser with cutters, affecting the feature of color changing.
Product features
Solvent resistance: Color-changing dye used in thermochromic capsules is sensitive to aliphatic solvent with a few carbons and resistant to aliphatic or aromatic solvent with a lot of carbons.
Thermal resistance: If high temperature needs to be applied, less than 10 minutes at 230℃ is recommended. A prolonged operation at high temperature higher than 75℃ must be avoided because thermochromic organic matters may be resolved at higher than 80℃.
Light resistance: Thermochromic products have the grade 1 light fastness, so extended exposure to sun may considerably reduce its color-changing effect.
FAQ
Q, What are the strengths of Thermochromic products?
A. The strengths of Insilico's Thermochromic products are high dispersibility, Clear color density, and rapid discoloration.
Q. What applications are available for slurry and powder products?
A. Slurry products have excellent dispersibility as the solvent is water. Applicable to water-based ink.
Powder products can be applied to solvent base oil-based ink and plastic injection.
Q. What is the ionicity of microcapsules?
A. Microcapsules become anionic under the influence of emulsifiers and dispersants used in manufacturing, and when used in combination with cationic surfactants such as most fabric softeners, it may cause agglomeration and troubles of the capsules. Avoid mixing them as much as possible, or use them within a range that does not cause trouble.
Q. What is the expiration date of the product?
A. It is safe for more than 2 years when stored in a cool dry place away from direct sunlight. Aggregation and delamination are normal during the storage period of the slurry and can be used after redistributing in a 45C water bath before use.
Q. How long does the discoloration function last when thermochromic product are applied to the product?
A. Thermochromic products are vulnerable to sunlight, so it is recommended to use indoor products. When applied to indoor products, the discoloration function can be maintained for more than 1 year, and the number of times of discoloration can be repeated 1000 times or more. Thermochromic products are react sensitively to the external environment, and their actual durability may vary depending on the user.
