Since early 2000, all CARTEC items grade 80 and grade 100 are supplied with photochromatic paint.
This paint has the characteristic of being an excellent overheating indicator because it can change its colour while temperature rises.
Over 390ºF, the product colour changes from red/orange to brown and it becomes black at 750ºF.
