Abstract:
The present invention relates to coloured fiber cement products as well as to methods for manufacturing such products. In particular, the present invention provides coloured fiber cement products, which fiber cement products are coloured in the mass, and at least comprise on at least part of their outer surface one or more cured layers of a coating composition, which composition at least comprises a binder and a pigment and/or a filler and is characterized by a pigment volume concentration (PVC) of between about 1% and about 20%. The present invention further provides processes for producing these coloured fiber cement products. Finally, the present invention provides uses of the coloured fiber cement products as building materials. In particular embodiments, the fiber cement products produced by the processes of the present invention can be used to provide an outer surface to walls, both internal as well as external, a building or construction, e.g. as fagade plate, siding, etc.

Abstract:
Stimuli responsive self-cleaning aqueous coating compositions for masonry and other substrates involving coatings that are durable, storage stable, ambient curing and recoatable comprising of smart polymers, which said coatings exhibits reversible super-hydrophobic and super-hydrophilic behaviour in response to external stimuli based variable environmental conditions such as variations in at least one temperature, pH, humidity and light; also exhibiting low contact angle hysteresis of 25 degrees with external stimuli. Said aqueous coating composition comprising a polymeric dispersion of either acrylic, fluorinated and amine backbone or acrylic, fluorinated and acid backbone in combination with hydrophobic and hydrophilic silicones and at least partially surface treated particles also including particulate mixture of micro and nano particles having balance of hydrophobicity and hydrophilicity, advantageously facilitates the attainment of contact angle hysteresis of
Abstract:
The present invention relates to a cementitious coating with hydrochromatic properties for micro-concrete or normal concrete, mortar, or other construction materials based on cement and ceramics. This cementitious coating in acrylic solution changes its opacity depending on the presence of water and moisture. This color change is reversible after some drying time leaving invisible the markings already existing on the substrate. This cementitious coating comprises the following components, in percentage in weight of the components relative to the total weight of the composition: a) 0.5-30% of hydrochromatic acrylic copolymer emulsion; b) 5-30% of white or gray Portland cement; c) 0.1-30% of finely ground limestone filler; d) 0.01-2% of powdered super-plasticizer; e) 0.01-3% of modified polyvinyl resins; f) 0.01-5% of dispersant of vinyl acetate and ethylene copolymers; g) 15-70% of aqueous acrylic emulsion; and optionally h) 0.1-15% of inorganic pigments.

Abstract:
Radiation-curable coating compositions for a surface such as a concrete floor, which include at least one multifunctional monomer or oligomer, at least one photoinitiator, at least one glossy band matting agent, and at least one matte band matting agent are described and claimed. These low gloss coating compositions allow for application of the coating composition over an area larger than a UV radiation source, while minimizing the formation of gloss bands or gloss lines that exhibit a different level of gloss in the areas where light leakage from a side light shielding of the UV radiation source results in a very weak radiation intensity, as compared to the areas subjected to high radiation intensity. These low gloss coating compositions are optionally clear topcoat compositions. In addition, a method for coating a surface with a radiation- curable coating composition that results in a cured surface with minimal differences in gloss exhibited following curing by a UV radiation source, and a surface coated with the radiation curable coating compositions of the instant claimed invention are described and claimed.
