AI Technical Summary
Conventional heat-resistant paints used in cooking appliances contain organic viscosity modifiers that oxidize, decompose, or carbonize at high temperatures, leading to discoloration of the heat-resistant resin layer, affecting its appearance.
A heat-resistant paint formulation containing a silicone resin component and transparent fine particles with an average particle diameter of 0.2 μm or less, preferably inorganic barium sulfate particles, is used to form a heat-resistant resin layer on a glass substrate, enhancing coating workability and suppressing discoloration.
The paint improves coating workability, maintains the desired color tone of the resin layer, and enhances storage stability, while preventing discoloration even in high-temperature environments.
