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.
