This local maximum exists because the pressure behind the shock decreases as a result of the exothermicreaction and/or geometric expansion. This is an exothermicreaction, so steps must be taken to control the temperature. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Temperature is sometimes increased in a step-wise fashion to control the rate of curing and prevent excessive heat build-up from the exothermicreaction.
