  • Patent number: 5368803
    Abstract: A fibrous resinated panel is provided which when used in a closed environment releases relatively minor amounts of trimethylamines, aldehydes and phenolic compounds into the closed environment. The panel is formed by compressing a fibrous mat impregnated with a thermosetting resin system in a mold cavity defined between an upper and a lower inner mold surface at a temperature between 400.degree. to 600.degree. for 45 to 90 seconds whereby the thermosetting resin is substantially cured and the mat is shaped to conform to a desired contour prior to removing the mat from the mold cavity. The thermosetting resin system used to impregnate the mat includes an essentially aqueous A-stage form resole-melamine composition containing residues of free melamine(s) to free aldehyde(s) to free phenolic compound(s) in a molar equivalent ratio ranging from about 0.2:1.5:1 to about 0.8:3.5:1.
