Expandable Graphite in painting industry

As a kind of physical expansion filler, expandable graphite will expand and absorb a lot of heat after heating to its initial expansion temperature, which can significantly reduce the system temperature and improve the fire performance of fire retardant coatings. The intumescent carbonized layer of the fire retardant coating after adding expandable graphite is burned by flame, and the odor and smoke generated in the expansion process are less than that of the ordinary fire retardant coating; Sungraf recommends that the appropriate addition of expandable graphite is 6%; The addition of expandable graphite with small particle size can effectively improve the fire resistance of the coating; In practical application of expandable graphite fire retardant coating, necessary curing time is required after coating.
