Abstract: Cold-pressed mats of lignocellulosic material having a Push Off Test extension equal to at least 85% of that of a mat made with a urea-formaldehyde resin are produced from a lignocellulosic material and binder system. These mats are produced at ambient temperature by separately adding each component of the binder system to the lignocellulosic material, blending the lignocellulosic material and binder system to coat the lignocellulosic material with the binder system, forming the coated lignocellulosic material into the desired form and applying pressure to the formed lignocellulosic material to obtain the desired thickness. The binder system includes: (i) at least one polyfunctional isocyanate and (ii) at least one aqueous dispersion of an adhesive or tackifier.
