Silicone-based food sealing compounds are indispensable in many sectors, especially food processing and packaging. These polymers offer a flexible, long-lasting, and safe way to seal joints and spaces where food may come into contact. It is essential to maintain the integrity of these seals in order to avoid contamination and uphold hygiene standards.

The outstanding resistance to temperature extremes exhibited by silicone-based food sealing compounds is one of their main characteristics. Their ability to maintain their sealing properties in extreme temperatures makes them perfect for use in a range of settings, including hot food processing areas and cold storage rooms. These compounds also maintain their flexibility over time, which guarantees long-term dependability.

Food-grade silicone sealants have a high level of resistance to UV light, chemicals, and moisture. This means that they can be used in places like kitchens, food factories, and outdoor spaces where food is prepared where they will be exposed to sunlight and cleaning agents. They are a reliable option for sealing applications in the food industry due to their non-toxic nature and adherence to food safety regulations.

It’s easy to use food sealing compounds made of silicone. Applying them is simple and requires only a standard caulking gun. They stick well to metal, glass, and some plastics. After curing, these sealants create an elastic, strong bond that holds up well under pressure, protecting food and maintaining hygienic conditions.

The food industry relies heavily on silicone-based food sealing compounds because of their special qualities, which include flexibility, durability, and resistance to high temperatures. These substances guarantee that containers have airtight seals, maintaining freshness and avoiding contamination. They are perfect for a range of applications, from large-scale food processing plants to home kitchens, thanks to their non-toxic, food-grade formulations that ensure they are safe for direct contact with food. Silicone food sealants are a dependable option for preserving hygiene and prolonging the shelf life of food products because they are simple to use and durable.

Properties and technical characteristics of food sealant

When baking silicone sealant comes out of the tube, it looks like a colorless, transparent, or white matte paste. Depending on the brand and composition, it freezes when it comes into contact with airborne moisture at different intervals. The material’s safety for human health, lack of hazardous contaminants, and ability to release harmful substances at high temperatures set it apart from other silicone sealants. These characteristics allow the product to be used with dishes, kitchen appliances, ovens, and other household items.

These sealants are typically utilized for the following uses:

• filling the joints in containers with water, filtering devices, tanks;
• strengthening joints, gaps at facilities in the food industry, dairy farms, cattle -boomes, catering establishments;
• sealing the seams of the pipeline for supplying warm, cold water in the city, rural areas;
• sealing various surfaces in institutions where sterility (operating, other facilities of hospitals) is required;
• Repair of home and professional household appliances: gas and electric slabs, electric kettlebells, multicoars, moonshine, etc. D.

The sealant can be applied vertically or horizontally, without draining or displacement for any reason. Following polymerization, the seam becomes a resilient silicone tire that is loved and safe to come into contact with food and water. The sealant must bear a label on the packaging that reads, "with a tolerance for use in the food industry," attesting to its non-toxicity.

Because the majority of food sealants are heat-resistant and high-temperature stable, they can be used to repair heating products without running the risk of property loss or seam destruction. Water resistance and outstanding adherence to metal, glass, ceramics, solid plastic, enameled, and painted materials are characteristics that set sealants apart. Alcohols, cleaning products, fats, and oils have no effect on the sealant-created seam. Since it is elastic, freezing does not cause it to crack.

The following are the technical attributes of premium silicone sealants:

• high mechanical resistance, the ability to stretch when the cracks are formed on the main product;
• significant chemical stability, the ability to withstand the effect of weak acids and alkalis;
• wear resistance, non -possession of atmospheric factors;
• the ability to quickly form a protective film (after about 10 minutes) and an early final drying (from 2 hours to a day);
• The tolerance of temperatures from -40 to +180-350 degrees or more.

The most widely used food sealant grades are Master Sil, Gebsicone Mastic Silicone, Tytan "Hermetic Silicone Foods," and others.

Composition of ordinary and food silicone

It is believed that silicone is entirely safe, so it can be utilized in the production of dishes. All silicones, which are a type of synthetic rubber, are members of the silicon-atom-based polymer family that connects organic groups to an inorganic silicon-acid chain. Both one- and two-component silicones need to be cured with a specific hardener.

Depending on the type of lateral organic groups and the length of the main molecular chain, silicone has different specific properties. The silicone used in food has a carefully regulated composition, and it is unique from other types due to additional ingredients that provide it with heat resistance and shield it from deterioration when it comes into constant contact with food and water. Make sure silicone products are non-toxic and susceptible to heating before purchasing. If not, silicone should not be used in the kitchen.

How to distinguish a fake from silicone

100% of premium food silicone is safe for human health. It is created with the GOST requirements and other regulatory acts pertaining to contemporary technologies in mind. Not only are there many genuine silicone products on the market, but there are also a lot of imitations. The following are the primary indicators that help differentiate them:

• dubious type of packaging;
• unpleasant odor;
• lack of description in Russian;
• white veins noticeable on the break;
• Too low price.

The best silicone to buy is silicone that has a CE marking on the package, indicating that the material complies with European standards. The FDA will mark silicone products if the management of food quality control (USA) approved them for sale after inspection.

Recommendations for the use of food sealant from silicone

Make sure a sealant has a high degree of adhesion and is well suited for the materials you plan to use before purchasing it. The item that needs to be sealed must then be expertly prepared. The following is the work order:

1. Elimination of pollution. The seams are cleaned, remove any dirt, dust, foreign particles that will reduce the quality of the clutch of the sealant with the surface.
2. Degreasing. To remove fat spots, oils before applying sealant, alcohol or acetone is used. The same solvents are suitable for cleansing integral bases with a smooth surface.
3. Grinding. This cleaning method is used for porous objects before the sealant. Manual cleansing is used using sandpaper, steel brushes or a grinding machine processing.

It is imperative to ensure that the base is completely dry and that the room temperature is between +5 and +40 degrees before beginning work with the sealant. Painting tape can be used to glue the seam’s edges first, then removed for a more precise and practical sealant.

Without using any drying accelerators, he should let the sealing layer dry after it reaches the appropriate thickness. A day later, the sealant layer is polished, and if necessary, the crawled areas are removed. White spirit, acetone, and ethyl alcohol are combined with mechanical scraping to clean the tool of sealant. Using a sealant based on granite or marble silicone is not advised. A test on elastomers, copper, and zinc should be conducted first in a discrete location.

For food preparation and storage areas to remain safe and long-lasting, silicone-based food sealing compounds are a must. Their special qualities, which include flexibility, toughness, and resistance to high temperatures, make them perfect for use in a variety of settings. By producing airtight seals that ward off contamination and spoiling, these substances preserve the nutritional value of food items.

The fact that silicone-based food sealants are non-toxic is another important benefit. They adhere to strict health and safety regulations and are designed to be safe for direct contact with food. Because of this, they are especially useful in kitchens, food processing facilities, and other settings where maintaining food safety is crucial.

Food sealants made of silicone are easy to apply and effective. They are a flexible solution for numerous sealing requirements because they stick well to a range of surfaces, such as plastic, glass, and metal. Silicone-based sealants work reliably when used to seal workspaces, equipment, or containers.

In conclusion, food sealing compounds with a silicone base are an essential tool for preserving food quality and safety. They are an essential option in both residential and commercial settings due to their dependability and simplicity of use.
