Abstract: A roofing granule can include a base particle having a base material and a layer covering the base particle of the roofing granule. The layer can has a first material and a second material that includes a metal carbonate, wherein the first and second materials include a same metal element, and the base material is different from the first material. In a process of forming the roofing granule, the layer can have pores. The process can include infiltrating a fluid into the pores of the layer while the base particle is present and adjacent to the layer, wherein the fluid includes a carbonate. The process can further include reacting the carbonate with a metal compound within the layer to form a metal carbonate within the layer. The roofing granules can be used in roofing products.

Abstract: A composite board is produced by the method of blending a cellulosic filler having sufficient extractable organic content and an expandable thermoplastic polymer, adding a tacifier agent during blending for producing a pre-blown mixture, heating the mixture in a mold to a temperature above the glass transition temperature of the polymer for a period of time sufficient to permit expansion of the beads and bonding of the expanded beads with the cellulosic filler to thereby form a composite board. The board may be laminated by a solvent based adhesive or a thermal insult coating so as to form rigid macro-voids between the laminate and the composite board surface.

Abstract: Improved moisture-resistant fire-retardant decorative floor and wall covering laminates and a method for making the same are described, having an asbestos backing, an intermediate layer of wood veneer and a face wear-resistant layer of vinyl, through which the decorative wood veneer may be seen. The vinyl wear resistant layer is usually clear and colorless. An optional colored vinyl layer may be laminated between the wood veneer and asbestos layer. The asbestos backing resists moisture penetration and transmits the moisture laterally to the edges of the laminate where it escapes. The asbestos and the vinyl face protect the wood veneer from fire, thus providing a highly fire-retardant and moisture-resistant, but decorative floor and wall covering.

Abstract: Porous friction facing materials containing cellulose fibers are coated with an impregnant of ethyl silicate to provide automatic transmission clutch plate and band linings of improved frictional properties, durability, wear and heat resistance, without use of asbestos. A sheet of paper-like fibrous material may be first impregnated with a phenolic resin binder which is cured to form a first coating and then impregnated with a hydrolyzed solution of ethyl silicate in a solvent. The material is further heated to drive off the solvent and cure the ethyl silicate to form a second outer coating having a higher coefficient of friction than the first coating. The silicate impregnated lining is then bonded to the steel plate or band. Alternatively, the resin impregnated lining material may be first bonded to the metal plate and then the entire plate assembly is impregnated with the ethyl silicate solution and cured.
