KV-LITE CLASS - D

KV-LITE CLASS-D fuses at temp. of above 600 °C and has high latent heat of fusion. The powder melts by absorbing s heat from the burning metal. It then forms a layer on the metal surface which is strong and provides a blanketing effect. Oxygen supply & heat radiation are thereby cut off from the burning metal surface. Anionic radicals of powder react with the free radicals of metals responsible for the fire propagation, this results into retardation of fire propagation chain reaction.
