A fire retardant coating composition for lignocellulosic materials which comprises expandable graphite particles, an absorbent material, a polymeric binder, a carbonific material, a blowing agent, and a wetting agent. The expandable graphite particles include from about 20 to about 95% by weight of the combined amount of the expandable graphite particles and the absorbent material. The polymeric binder comprises from about 5 to about 50% by weight of the combined amount of the polymeric binder, the expandable graphite particles, and the solid absorbent material.
L'invention concerne une composition de revêtement ignifuge pour matériaux ligno-cellulosiques qui comprend des particules de graphite expansibles, un matériau absorbant, un liant polymère, un matériau générateur de carbone, un agent d'expansion et un agent mouillant. Les particules de graphite expansibles sont composées à raison de 20 à 90 % en poids environ de la combinaison particules de graphite expansibles et matériau absorbant. Le liant polymère est composé à raison de 5 à 50 % en poids environ de la combinaison liant polymère, particules de graphite expansibles et matériau absorbant solide.
