摘要:
The present invention relates to coloured fiber cement products as well as to methods for manufacturing such products. In particular, the present invention provides fiber cement products that are coloured in the mass, which fiber cement products 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 coated fiber cement products that are coloured in the mass. 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 façade plate, siding, etc.

摘要:
A method for metallizing a surface of a ceramic substrate includes molding and sintering a ceramic composition to obtain the ceramic substrate, in which the ceramic composition comprises a ceramic powder and a functional powder dispersed in the ceramic powder, radiating a predetermined region of the surface of the ceramic substrate, and performing chemical plating on the ceramic substrate.
摘要:
Radiation-curable coating compositions for a surface such as a concrete floor, which include one or more acrylate monomers or oligomers having at least four crosslinkabie double bonds, at least one photoinitiator, one or more fillers, and at least one pigment or dye are described and claimed. These coating compositions allow for application of at least 0.10 mm (4 mil) thickness of the coating composition over an area larger than a radiation source, without the formation of wrinkles along the shoulder area of each pass of the radiation source in the areas where weak intensity light from a side edge of the radiation source is capable of partially curing only a portion of the coating composition thickness. The coating compositions optionally further comprise one or more tertiary amine compounds comprising zero or one crosslinkabie double bonds, the one or more tertiary amine compounds providing an amine value of at least 7.5 mg KOH per gram of the total radiation-curable resins of the coating composition. In addition, a method for coating a surface, and a surface coated with the radiation curable coating compositions of the instant claimed invention are described and claimed.
摘要:
The invention relates to a process for applying a liquid UV-curable primer sealant to natural stone tiles and related articles followed immediately by the exposure to a requisite amount of low intensity UVA-type UV radiation to partially cure the primer sealant. The partial curing, or pre-setting, of the primer sealant enables control of the ultimate depth of penetration of the primer sealer into the natural stone tiles and natural stone articles of which many examples are quite porous. Because the low level UV irradiation is instantaneous after the primer sealant application the level of primer sealant penetration into the natural stone surface is regulated. The pre-curing of the primer sealant is conducted to intentionally solidify or immobilize the sealant that has actually penetrated into the natural stone surface. The uppermost layers of the primer sealant are left in a semi-liquid or uncured state to allow for wetting and intermingling by the top sealant once it is applied. Thus, the prior art problem of uncontrolled wicking is solved by the present invention.
