Figure 3.
The horizontal axis shows temperature from 50 to 600 degrees Celsius and the vertical axis shows weight from 0 to 100 per cent. The D D S A curve remains near 100 per cent until about 150 degrees Celsius, then decreases rapidly to 0 per cent by about 220 degrees Celsius. The top layer formulation remains near 100 per cent until about 150 degrees Celsius, decreases gradually to about 93 per cent near 300 degrees Celsius, then declines sharply to 0 per cent by about 470 degrees Celsius. A dashed vertical line marks 150 degrees Celsius, and an annotation indicates loss of anhydride.Thermogravimetric curves of uncured top layer formulation and DDSA
