Shaped bodies such as board can be made from a mixture of comminuted vegetable matter and an isocyanate binder by forming the mixture with a moisture content in excess of that required to cure the binder, then coating a support for the mixture with a layer of a liquid parting agent, depositing the mixture on the support, coating the mixture with another film of the parting agent and hot pressing the mixture to form the board.
