  • Patent number: 4263093
    Abstract: A low-cost mineral-fiber board having a natural-appearing highly textured surface, and improved uniformity of density is produced by coating the wet-textured surface of a perlite-containing mineral-fiber mat to a depth at least equal to the peak height of the texture with a layer of silicone-coated perlite prior to press-forming the board. The perlite layer fills the voids on the textured surface and provides a buffer layer between the board and press roll, enabling uniform pressure to be applied to the board without disturbing the textured surface. The top perlite layer may be removed by vacuum units before or after drying the board.

  • Patent number: 4066805
    Abstract: Mineral or wood fiberboard is provided with a disrupted or embossed decorative surface, painted overall with a paint containing yellow pigment grade ferric oxide pigment, and the high areas contacted with a heated surface at a temperature such that the ferric oxide pigment is heated to drive off the water of hydration and convert it to a red ferric oxide, thus achieving a two-toned decorative painted board product.
