In terms of processing performance
Easy to process and shape: It should be easy to apply to the surface of corresponding food contact products through common coating processes (such as spray coating, immersion coating, brush coating, etc.), and can be smoothly formed according to the set process parameters during the curing process, ensuring uniform and stable coating quality to meet the needs of large-scale production.
Good compatibility with other materials: In some cases, silicone resin coatings may need to be used in conjunction with other materials, such as the underlying metal, ceramic, or other substrates, or with additives used to enhance performance. It is required that they have good compatibility with each other, and there will be no issues such as delamination or incompatibility that affect the overall performance of the coating.
Hygiene and cleanliness aspects
Cleanliness: The coating surface should be easy to clean, capable of easily removing food residues, oil stains, etc. attached to it, ensuring the hygiene of the food contact surface, preventing bacterial growth, and maintaining good performance after multiple cleaning processes, without being damaged by friction, chemical cleaning agents, etc. during the cleaning process.
Microbial resistance: It can resist the erosion of microorganisms (such as bacteria, mold, yeast, etc.), prevent the growth and reproduction of microorganisms on the coating surface, avoid food safety risks caused by microbial contamination, and maintain the cleanliness and hygiene of the food contact environment.
