<p>A temperature indicating paint comprises 4wt% to 40wt% sodium alumino sulpho silicate, 1wt% to 38wt% nickel antimony titanate and the binder comprises 25wt% to 50wt% silicone resin 10wt% to 30wt% acrylic resin each excluding solvent. This composition undergoes colour changes occur, these are; Blue 520-560°C; Light Blue 950-990°C; Light Yellow 1000-1040°C; Glazed Black 1160-1200°C. The colour changes are particularly distinct and enable accurate analysis particularly, but not exclusively, in gas turbine engines.</p> |
