Chief there was an article in a fire service publication about this very subject and the research that the wife did. It didn?t gain much attention at the time. I?ll share if I can find it again. The chemicals in question are used to raise the TPP level of the gear which is the thermal rating of the gear. The higher the thermal rating the more marketable the gear is. If this gains the ground it should it will be a huge blow to the manufacturers and vendors as it should be. As she said. It?s the ultimate deception.
