In a preferred embodiment, the phosphorous containing flame retardant has a Surface coating thereon which reduces sensitivity of the flame retardant to water, and thus reduces the amount of the flame retardant that can leach out in the presence of water, thereby enabling the composi (22) Filed: Nov. 13, 2007 tions of the present invention to be utilized outdoors or other environments where exposure to water or high humidity is possible. The hardness of the compositions according to the invention preferably ranges from about Shore A 40 to about (51) Int. Cl. Shore A 90. The compositions exhibit high char formation CSK 3/32 (2006.01) upon burning and also desirable vertical burn characteristics. (21) Appl. No.: 11/983,986
