Abstract
Disclosed is a solid binder composition containing from about 70 to about 98 percent by weight of TDI residue and correspondingly from about 2 to about 30 percent by weight of a select ester derived from a dicarboxylic acid. When the binder composition is used in making lignocellulosic composite materials, such as particle board, the ester acts as an effective internal mold release agent, facilitating release of the composite material from the mold.
