摘要:
The invention relates to pavements for thoroughfares and related safety and/or marking elements having enhanced reflective properties, comprising 10 to 80% by weight of glass debris which contains at least 10% by weight of essentially reflective glass debris less than 20 mm in size. It also relates to a composition for such thoroughfare pavements or related elements. The invention applies more particularly to the construction of thoroughfares such as roads, cycle tracks, walkways, etc. or related elements such as concrete crash barriers, curbs of pedestrian pavements, bollards, etc.
摘要:
An improved finely divided rubber-reinforcing clay mineral composition can be produced by employing a hydrous kaolin clay surface treated with a functional silane, a methylene donor compound such as hexamethylenetetramine, and a multifunctional methylene acceptor such as resorcinol. A novel process of preparation is provided. The improved reinforcing, treated clay filler can be combined with natural or synthetic elastomer compositions which can be cured to elastomer products which have improved physical properties, such as modulus, tensile, tear, wear resistance and/or resistance to heat build-up.
摘要:
There is disclosed a cement plaster composition wherein an additive having from about 10% to about 75% of a silicone treated powder and from about 90% to about 25% of a pozzalanic filler is combined with a type I Portland cement and a crushed aggregate to form a water repellent coating for plastering a swimming pool surface. The additive may also include rheology modifiers, water reducing agents, or set time modifiers.
摘要:
Cycloaliphatic compounds, which have one or more ethylenically unsaturated substituents, are disclosed as components of borehole-filling masses, optionally together with other curable components.
摘要:
An aqueous liquid or sludge waste is solidified by mixing it with a clay selected from the group consisting of sodium Montmorillonite, attapulgite, sepiolite, and mixtures thereof and a cementitious material coated with a fluid silicone polymer.
摘要:
An inorganic pigment comprising a content of at least 0.1% by weight and at most 5% by weight of one or more polyorganosiloxanes, wherein the polyorganosiloxanes have viscosities of 10 to 100,000 mPa.s and a relative molecular weight of 500 to 500,000, have no reactive or crosslinking groups, contain at least one C.sub.9 -C.sub.25 Si-alkyl and/or one C.sub.9 -C.sub.25 Si-aryl group per molecule, the total content of these groups in the polyorganosiloxane being 7-70% by weight and the other organic radicals contained in the polyorganosiloxane having 1 to 8 carbon atoms. Such pigments can be used in lacquers, emulsion paints, plastics, toners, magnetic recording materials, building materials and enamels.
摘要:
A 1 to 8 micron organic/inorganic (epoxy/glass) wear surface coating over a clear, protective layer provides excellent stain and gloss protection. An acid hydrolyzed silicate is combined with an acid hydrolyzed silicone coupling agent; an epoxy monomer; a photoinitiator and silicon oil surfactant to produce a coating composition which is dried to remove alcohol/water solvent and U.V. cured.
摘要:
A grout material comprises a pulverulent body having a silicone coating portion formed on at least a part of the surface of a base material. The particle size of the pulverulent body ranges from 1 to 10 .mu.m. A grouting method using a grout material comprises the steps of boring a hole in a predetermined portion of an area to be grouted, supplying to the hole a powdery grout material containing a pulverulent body having a silicone coating portion formed on at least a part of the surface of a base material and thereby grouting the grout material into the periphery of the hole.
摘要:
A water repellent composition being liquid at room temperature, which comprises a silicone oil and a substantially non-volatile paraffinic oil or low molecular weight resin, wherein the separation index of the paraffinic oil or low molecular weight resin to the silicone oil is at most 0.4.
摘要:
Expanded perlite coated with an amino-functional siloxane and a silicone wetting agent, and a joint compound incorporating same, which, when applied to gypsum wallboard, has improved bonding properties and greater uniformity in paint gloss appearance between the surface of the joint compound and the surface of the wallboard.
