Thermal Color Changing Powder Description:
Ranbar Orange WS2030 is a thermal color changing powder produced using microcapsule coating technology. It has the appearance of fine spherical powder. Due to its sensitivity to the external environment, microcapsule technology is employed to enhance its stability and durability. Ranbar WS2030 Thermal Color Changing Powder transitions from colorless to orange with a rise in temperature and reverts to its original color when the temperature is restored.
Suggested Dosage of Thermal Color Changing Powder:
It is recommended to use 0.5% to 2% of Thermal Color Changing Powder for resin or plastic casting, or other plastic products. If the product material is already colored, up to 2.5% of Thermal Color Changing Powder should be used. Plastic fillers such as titanium dioxide, calcium carbonate, carbon black, flame retardant, or other pigments can cover the color of Thermal Color Changing Powder. For printing inks and paints, it is advisable to add 8% to 12%.
Precautions for Thermal Color Changing Powder:
- Mixing and Friction:
To prevent mechanical damage, minimize friction during the manufacturing process. Use low-speed mixers, hand mixing, three-roller mills, or other gentle methods. Avoid high-speed agitators or ball mills, as they can quickly damage the pigment structure. Steer clear of repeated extrusion operations, and consider using dispersants to reduce mixing times. - Media Requirements:
The microcapsules containing Thermal Color Changing Powder are a few microns in size. Use solvents with no more than 3 carbon atoms (e.g., methanol, ethanol, or acetone) cautiously, as they can penetrate the thin walls of the microcapsules and disrupt the pigment structure. Solvents with 6 or more carbon atoms in the particles are considered safe for the pigment. - UV Resistance:
Thermal Color Changing Powder is sensitive to UV rays. If the product is frequently exposed to direct sunlight outdoors, cover the finished product colored with Thermal Color Changing Powder with a lacquer containing UV protection.
