摘要:
The invention relates to domestic appliances bearing on a powder-coated surface a scratch-resistant and abrasion-resistant topcoat of a coating material which comprises: a) condensates based on hydrolysable silanes containing at least one non-hydrolysable substituent, the hydrolysable silanes having an epoxide group on at least one non-hydrolysable substituent; b) a curing catalyst selected from Lewis bases and alkoxides of titanium, zirconium or aluminium; c) nanoscale particulate inorganic solids having a particle size in the range from 1 to 100 nm; and d) at least one organic monomer, oligomer or polymer containing at least one epoxide group.
摘要:
Domestic appliances are provided with a catalytic deodorizing coating, prepared by applying a coating material containing a polycondensate of at least one hydrolysable organosilane, optionally one or more compounds of glass-forming elements, and particles of one or more catalytically active transition metal oxides, and then heat-treating the applied coating material.
摘要:
A coating solution made from a mixture of at least one silane and at least one polysiloxane which can be hardened on a substrate by hydrolysis and condensation to give a coating on the substrate, wherein the at least one silane is of general formula PxSi(OR′)4−x and the at least one polysiloxane is of general formula [R2SiO]y or R3Si—(O—SiR2)Y—O—SiR3, where R independently=alkyl, aryl, arylalkyl, alkylaryl or H, Rprime independently=H, methyl, ethyl, n- or i-propyl, n-, iso-, sec.- or tert.-butyl, x=0 or 1 (for the first silane), x=0, 1 , 2, 3 or 4 (for each further silane) and y=a whole number of at least 2, wherein the coating solution includes at least one alkali or earth alkali oxide or hydroxide.
摘要:
A cooking appliance having a cooking space with a micro-rough surface. The micro-rough surface is formed on a metal substrate. In order to better clean the micro-rough surface from dried or charred food material, the layer includes an enamel formed of a glass flux with separate crystal zones spaced from one another formed and embedded in the enamel. The crystal zones are formed by crystallizing portions of the enamel into crystalline phases, forming a rough superstructure with a plurality of fine structures on the surface of the superstructures.
