Description
  • Microencapsulated organic thermochromic pigments may have varied industrial applications, such as in windows and greenhouse roofs. Two black coloured commercial microencapsulated pigments from A and B brands are used in this work. The study is conducted with UVA irradiation, and simulation of atmospheric conditions (weathering tester QUV). After a few degradation cycles, the colour of the substrate becomes a yellowish hue, which suggests that chemical degradation of the components of the microcapsule has ccurred. It is concluded that the material of the microcapsules is melamine formaldehyde and two of the core components are probably crystal violet and benzotriazole, which are assumed to act as a UV absorber and promoter of proton transfer. A study is also implemented on the effect of adding DABCO to the suspensions of the pigments, which are then irradiated with UV light. A somewhat protecting effect is observed.
