Abstract: A rigid foam having increased flame retardance comprises the reaction product of an isocyanate component and an isocyanate-reactive component. The isocyanate component and an isocyanate-reactive component are reacted in the presence of an isocyanurate catalyst component and a carbodiimide catalyst component. The isocyanurate catalyst component comprises 1,3,5-tris(3-(dimethylamino)propyl)-hexahydro-s-triazine and the carbodiimide catalyst component comprises 3-methyl-1-phenyl-2-phospholene-1-oxide. A method of forming the rigid foam on a surface comprises the steps of providing the isocyanate component, providing the isocyanate-reactive component, providing the isocyanurate catalyst component, providing the carbodiimide catalyst component, and spraying the isocyanate component, isocyanate-reactive component, isocyanurate catalyst component, and carbodiimide catalyst component onto the surface to form the rigid foam on the surface.
