Abstract: Rounded quartz sand particles (22) are each enclosed in a hardenable resin skin (23) which is integrated with the skins on adjacent particles and which creates a binding of the particles to a primed base (20, 21). A significant fraction of the particles may be remote from the base and only integrated with adjacent particles so that a contoured or embossed effect is created to provide a supplementary non-slip feature. In a process for forming such a surface coating the particles are wetted with a functional liquid, mixed with a binder related to the functional liquid and sprayed. The spraying process is powered by a progressive cavity pump (37) with a selection of particle/resin ratio such that the pump operates under a Sigma effect.

These BUR products are made using improved glass fiber mat structures having unusual tear resistance in place of organic felts.The glass fiber mats are constructed from two fibrous components, namely, individual filaments, which provide the uniform denseness required for impregnation of saturant asphalt in the interstices of the mat, and extended fiber elements formed by longitudinal extension and connection of fibers from bundles of glass fibers in a wet-laid process, which furnish tear resistance and tensile strength to the BUR membranes and systems.The BUR membranes and systems of this invention have exceedingly high strengths compared with commercially available products of similar construction, and, advantageously, they can be manufactured by a very economical process.

Abstract: Asphalt roofing material is made fire-retardant by inclusion of a layer of intumescable hydrated soluble silicate particles. Preferred soluble silicate particles carry a protective moisture-resistant coating which increases the life of the roofing material, and also makes possible convenient manufacture of the particles. The protective coating includes a metal cation capable of reacting with the silicate ion of the core particle to form a reaction product that is less soluble than the core particle. The reaction is believed to seal any openings in the protective coating, thereby lengthening the effective life of the coating. Besides utility in roofing materials, the coated particles are useful as fire-retardant additives in many other products, including polymeric articles, sheet materials, coating compositions, etc.

Abstract: A particle having superior bonding properties comprising crystalline portions connected together by a bonding material. The bonding material is relieved at the surface of the particle to provide capillaries extending into the particle between adjacent crystals. This results in the fusing material having a terminal surface recessed from the surface of the particle. The particle, when added to an elastomeric material, achieves superior mechanical, chemical and vacumatic bond strength as the elastomeric material is anchored to the particles by occupation of the capillaries, achieving increased bonding area.
