Abstract: Disclosed are methods for coating a substrate. These methods include: (a) preparing a two-component coating composition by mixing a first component and a second component to make a mixture thereof, and (b) depositing the mixture over the substrate to form a film having a 60° gloss of no more than 35 gloss units (measured according to ASTM D523-89). In these methods: (i) the first component includes: (A) an aqueous anionic, aliphatic polyurethane dispersion comprising a polyurethane having terminal methylol groups; and (ii) the second component comprises an aqueous anionic acrylic polymer solution having a viscosity of 25,000 to 60,000 mPa·s at 20° C. when measured according to DIN EN ISO 3219 at a non-volatile content of 9% to 11% by weight, based on the total weight of the solution, measured according to DIN 53189.

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.
