Thermo chromic material
1. C olor change principle :
The rmochromic pigment is microcapsule product which is reversible, it changes color at different temperature.
2. T he 15 standard colors:
Colo rs appear i n low tempe rature rang e and change to opaqu e in high te mperature r ange. Besides the 15 c olors, other can be assign ed.
Red ,Rose Red ,Magenta ,Vermillion ,Ora nge ,Yellow ,Y. Green ,C. Green, Gre en , Sky Blu e, T. Blue ,Blue , D. Bl ue ,Violet, Bl ack
3. Reference of a pplied color s:
The colors can be mixed tog ether, and also by adding other pigment to get ot her color effects. Temperature range from 15 to 70 (The standard colors shown above are p rinted by general ink, please apply the correct c olor from Thermochromic ink.)
5. The styles and property of the thermochromic materials:
?The particle dimension of thermochromic MC powder is about 1~10 µm, the highest temperature of heat endurance is 280 . It has the good property to resist solvents and disperses into them. (MC powder means microcapsule powder).
?Aqueous slurry of thermochromic product is water dispersion containing microcapsule. The solid content of the slurry is about 48%, the slurry may apply for water-based screen printing, coating, spraying, and dying.
?Thermochromic plastic master batch, which contains MC powder around 12~18% depending on the color density of different color material could use in plastics production. ?Thermochromic material should be kept in a dry place, under room temperature and in a place where not exposed to light. The storage time of thermochromic powder and master batch is not more than 2 years.
6. Application and usage of the produces:
Suggested working concentration
MC powder for oil-based coating 5% ~ 30% w/w MC powder for water-based coating 3% ~ 30% w/w MC powder for plastic injection & extrusion 0.2% ~ 3% w/w Aqueous slurry for water-base coating 5% ~ 60% w/w Master Batch for plastic injection & extrusion 1% ~ 5% w/w Thermochromic products are available in many fields.
Paints: For a variety of surface coating on plastics including ABS, Polyethylene, Polypropylene, and Polystyrene, PVC, PVA and other substrates. Inks : For lots of printing types, including screen, gravure, and flexographic printing and mammy substrate like fabrics, paper, synthetic films, glass, ceramics, wood est.
Plastics: Plastic concentrates for molding with ABS, Polyethylene, Polypropylene, Polystyrene, PVC, PVA, Polyester, and Nylon.
