摘要:
A system and a method include a substrate wrinkled coating having a substrate, and a curing layer on top of the substrate. The curing layer includes a partially cured portion directly atop the substrate, and a completely cured portion having light-diffusive wrinkles on top of the partially cured portion. Properties of the light-diffusive wrinkles are controlled by one or more curing parameters, and a composition of the partially cured portion is the same as a composition of the completely cured portion.
摘要:
A process for imparting a simulated patina appearance to a copper substrate including selecting a colorant having the desired initial patina color tone and producing a noncontinuous layer of the colorant on a surface of the copper substrate to provide the appearance of patination of the desired tone via interspersed spots of the colorant. The remaining portion of the substrate is exposed for natural patination.
摘要:
A method for the temporary protection of patinated surfaces of copper products, in which an aqueous polymer dispersion is applied to the patinated surface, so that the polymer dispersion penetrates regions of the porous patina that are close to the surface, and in which the aqueous polymer dispersion is subsequently dried, so that it forms a composite with the patina that is permeable to water vapor diffusion. The polymer dispersion binds loose dust located on prepatinated copper products and simplifies the handling of the copper products. It behaves in a hydrophobic manner, but on the other hand it permits the required access of air moisture and water to the patina layer for further weathering.
摘要:
A curable coating composition includes a polyester, a curing agent for curing the polyester, a curing catalyst, a composite solvent having at least two solvents with different dissolving powers for the polyester, and a wax incompatible with the polyester. A method for making a coated metal plate having an embossment-like texture formed from the coating composition, and the coated metal plate made thereby are also disclosed.
摘要:
A method of weathering a model of an object is described. The model to be weathered most desirably is a hobbyist model, such as used by model railroaders and military modelers, and it is rust that is simulated. A suspension of a rust-colored coloring agent is applied to the surface of the model within a carrier which is adapted to spread the same as flakes over the surface. The carrier is then removed by drying the model to leave the flakes. A second coloring agent of a different color is applied to the model over the dried flakes to enhance weathered appearance.
摘要:
The present invention relates to a three-stage UV curing process whereby a UV-curable substrate is initially exposed to long wave length light of low intensity, thereby causing the bottom portion of the substrate to gel while leaving the top surface essentially unaffected. The first stage irradiation is followed by irradiation with shorter-wave length UV light under an inert atmosphere, thereby causing the surface of the substrate to gel. The final stage of the curing process involves conventional exposure to strong UV light whereby the entire structure is cured to give a product having finely controlled surface texture. The resulting products are useful as surface coverings, and particularly as floor and wall coverings.
摘要:
An epoxy coating powder applied in a fusion coating process that yields a low gloss, wrinkled finish. The coating composition is a heat reactive epoxy resin in which the wrinkled finish results from the use of methylene disalicylic acid as the curing agent for the epoxy resin.
摘要:
A process for the preparation of decorative articles having a patterned coating of an inorganic paint, which comprises coating a solvent having a water solubility of at least 20% or a mixture of said solvent with an organic or inorganic binder or an inorganic filler on a substrate, allowing the coated substrate to stand, coating an inorganic paint of the silicate type on the coated surface of the substrate, and then drying and hardening the coating.
