Ingredient disclosure

Comments19 20 :

A thermally unstable substance liable to undergo a strongly exothermic decomposition. Laboratory testing performed on the substance as packaged is nescessary to determine the category (Type A to G) of this hazard class.

This product could belong to the hazard class "Combustible dust", based on various factors related to the combustibility and explosiveness of its dust, including composition, shape and size of the particles.
