Introduction to weather resistance of photosensitive color changing powder

reversible photosensitive color changing powder has far less light resistance, heat resistance, aging resistance and other properties than ordinary pigments. Attention should be paid in use:

1. Light resistance: photosensitive color changing powder has poor light resistance and will fade and fail quickly under strong sunlight exposure, so it is only suitable for indoor use. Strong sunlight and ultraviolet light should be avoided, which is beneficial to prolong the service life of color-changing paint.

2. Heat resistance: avoid working at temperatures above 75℃ for a long time.

The exposure time of photosensitive toner applied in different resin is different. The continuous exposure time may only be 5-12 hours, and the discoloration effect will be greatly weakened. But when used indoors at room temperature, the color changing effect can reach several years. For example:

it can be used for two years after being dried for 10 minutes every day.

15 minutes a day can be used for one and a half years.

It can be used for one year after being dried for 20 minutes every day.

It can be used for three months after 25 minutes of sun exposure every day.

Note: The above exposure service life should be judged according to the actual application, and the service life of each product will be different depending on the service environment and temperature.
