Composite facer for wallboards

   
   

A composite facer material for use with cementitious wallboards, where the composite facer is embedded in a top and bottom face thereof. The composite facer material, in a most preferred embodiment, comprises two layers. The first layer is preferably a carded polyester nonwoven mat, which is bonded to a second layer comprising preferably a tri-directional laid scrim fabric reinforcement layer made of continuous glass fibers. The two layers are preferably bonded together using an acrylic adhesive, which offers superior adhesion between the layers as well as superior adhesion between the composite facing material and the cementitious core.

Un material compuesto del facer para el uso con los cartones de yeso de cemento, donde el facer compuesto se encaja en una tapa y una cara inferior de eso. El material compuesto del facer, en una encarnación preferida, abarca dos capas. La primera capa es preferiblemente una estera no tejida carded del poliester, que se enlaza a una segunda capa que abarca preferiblemente una capa puesta tri-direccional del refuerzo de la tela de la crehuela hecha de fibras de cristal continuas. Las dos capas se enlazan preferiblemente junto con un pegamento de acrílico, que ofrece la adherencia superior entre las capas así como la adherencia superior entre el material compuesto de los revestimientos y la base de cemento.
