The tools required for coating silicone depend mainly on the specific coating process and application scenario. Here are some common tools required for coating silicone:
Mixing container: A container used to mix and stir silicone and its curing agent (if necessary). It is usually recommended to use a plastic container and ensure that the silicone solution does not exceed 1/3~1/2 of the container to prevent overflow.
Mixing knife or stirrer: A tool used to evenly stir silicone and its curing agent in a container. The mixing knife has different sizes and can be selected according to the amount of stirring.
Vacuum defoaming machine: Used to eliminate bubbles in the silicone mixture to ensure that the surface of the silicone after coating is flat and free of bubbles. If food-grade AB silicone is used, and the hardness is within 30 degrees and it is not particularly thick, sometimes a vacuum machine can be omitted and a small amount of curing agent can be added to delay solidification to achieve the purpose of defoaming. However, if it is industrial mold silicone, it is best to purchase a vacuum machine for long-term production.
Brush: If the coating is done by brushing, a brush is required. The choice of brush should be determined according to the viscosity of the silicone and the coating area.
Scraper: Used to scrape the silicone evenly on the surface of the substrate, especially in the coating process that requires a certain thickness uniformity.
Coating machine: For large-scale coating operations, coating machines can be used to improve efficiency and precision. Coating machines can be customized according to process requirements, such as silicone coating machines, automatic dispensing machines, etc.
Mold: In some coating processes, such as silicone mold turning, molds are required to shape silicone. The selection and production of molds should be determined according to specific product design and requirements.
Release agent: Used to prevent silicone from bonding to molds. Although silicone will not bond to some materials, using a release agent can be more secure.
Other auxiliary tools: such as electronic scales (used to accurately weigh the ratio of silicone and its curing agent), wooden boards or baffles (used to prevent silicone from overflowing or protecting the surrounding environment), scissors (used to trim excess silicone or mold materials), etc.
Please note that the specific coating tool selection should be determined according to the type of silicone, the requirements of the coating process, and the scale of production. When selecting and using tools, be sure to follow the relevant safety operating procedures to ensure the safety of operators and coating quality.
