Abstract:
The present invention is directed to cement-based coating compositions providing a stable, hard, fast setting and drying cement coating. In particular, the cement-based coating includes a low-flashing, VOC-exempt solvent in combination with cement materials, aggregates, resins and other optional components. Methods of making, application and use of the cement coating composition are further disclosed herein.
Abstract:
A cover composition that can be applied to a bulk material pile, such as landfill refuse, to protect the pile from wind, precipitation, and access by animals and insects is provided. The cover composition is a mixture of a liquid, typically, water; bentonite clay; and synthetic fibers. The composition may be enhanced by the addition of one or more of the following additives: Portland cement, pregelatinized wheat starch, synthetic polymers, soda ash, and latex paint. Unlike prior art cover compositions, the disclosed composition adheres well to waste material, most notably plastics, whereby the composition is easy to apply and provides a substantially uniform, durable protective cover to landfill refuse piles and other bulk materials. Methods of applying the composition to bulk material piles are also disclosed.
Abstract:
Process for the preparation of aqueous dispersions of (co)polymerizates using a polymer with cationic functionality, optionally accompanied by the use of conventional additives, the polymer with cationic functionality being obtained by (co)polymerization in an aqueous medium of olefinically unsaturated (co)monomers, in which at least one (co)monomer has a cationic functionality, further (co)monomers are added and polymerization takes place in the presence of suitable initiators, wherein the polymers and/or (co)monomers are so chosen and the process is so controlled that a (co)polymerizate particle with heterogeneous morphology is formed and the dispersed (co)polymerizate obtained has a glass transition temperature Tg of more than about 50° C. The invention also relates to a process in which the polymer with cationic functionality is formed in situ in the presence of a seed. Redispersible powders and the use thereof are also described.
Abstract:
The present invention relates to a coating composition and method of manufacturing said coating composition. The coating composition is a two-component coating composition for construction surfaces. The present coating composition is effectively bonded to the surface without an additional application of intermediate layer overcoming the existing problems associated with conventional concrete surface treatment methods.
Abstract:
The invention provides a composition having a bulk density of 0.8 g/cm3 or less comprising (a) 25-65 weight % of an inorganic binder comprising (i) 83 to 100 weight % of calcium aluminate cement, (ii) 0 to 14 weight % of calcium sulphate, (iii) 0 to 9 weight % of portland cement wherein the weight % of (i), (ii), (iii) is based on the sum of (i)+(ii)+(iii), (b) 0.5-15 weight % of one or more organic polymers, (c) 30-75 weight % of one or more inorganic fillers wherein the bulk density of the fillers is less than 0.5 g/cm3, wherein weight % is calculated on the total weight of all the non-volatile components in the composition.
Abstract:
The invention provides for the use of dry building materials comprising one or more polymers in the form of water-redispersible powders, and optionally mineral binders, optionally fillers and optionally additives, for the surface treatment of cementitious substrates that are as yet not fully set.
Abstract:
A coating for metal ship decks that provides skid resistance and corrosion protection using a polymer emulsion and aggregate layer over an epoxy layer and sealing the polymer emulsion and aggregate layer with xylene.A method of application of an epoxy layer prior to application of the polymer emulsion to provide a corrosion resistant layer beneath the cementitious coating and then applying a xylene sealant to the cementitious coating.
