Uses of Food-Grade Silicone Adhesive
14 Oct 2026
Food-grade silicone adhesive is a bonding agent certified under the GB 4806.1-2016 safety standard for food-contact materials. Upon curing, it is non-toxic, odorless, and free from harmful substance leaching, making it safe for direct contact with food, drinking water, and heating appliances. It also offers high/low-temperature resistance, waterproof sealing, and strong flexibility, serving applications across industrial production, healthcare, and household settings.
I.Food Processing and Food-Contact Equipment
①Sealing and repair of food-contact components: Used to repair broken seals in health kettles, glass cups, and water dispensers, as well as to seal joints in food-grade silicone tubing and hot-air ducts for baking equipment; it withstands high-temperature steaming and standard food-grade CIP (Clean-in-Place) processes.
②Food mold making and bonding: Suitable for bonding silicone components in molds for chocolate, candy, and cakes; also used to reinforce joints in flexible food-grade silicone connectors to prevent leakage during material transport.
③Food production equipment assembly: Used in dairy and beverage processing lines to seal and bond joints between food-grade pipes and reaction tanks of varying diameters, reducing potential leak points during disassembly and cleaning.
II.Healthcare and Medical Fields
①Medical device manufacturing: Used to bond silicone components for wearable monitoring devices, wound care products, external orthotics, and prosthetics; passes biocompatibility testing for safe direct contact with human skin.
②Medical consumable assembly: Suitable for bonding silicone parts in ostomy care products, surgical dressings, and patient monitoring electrodes; ensures low irritation and low allergenicity, allowing for gentle removal from the skin.
III.Industrial and Electronics Manufacturing
①Silicone product assembly: Used for the direct bonding of silicone components in products such as adult products, children's silicone toys, and baby bottles; for most products, it achieves a bond where the silicone material itself tears before the adhesive fails, eliminating the need for primers.
②Sealing and protection for electronic devices: Used to seal the housings of electronic devices requiring high environmental protection standards; leverages excellent insulation, moisture resistance, and chemical resistance to protect internal components from moisture ingress.
IV.Everyday home repair scenarios
①Kitchen appliance repair: Repairs cracked glass seasoning jars, stove anti-slip mats with failed adhesive, and washing machine door seals; the bond is odorless and does not turn white, remaining secure even with prolonged exposure to water and high temperatures.
②Bonding of everyday items: Used to bond silicone components in products that come into contact with skin or food—such as facial cleansing devices and silicone kitchenware—meeting safety and durability requirements for daily use.
