Odake Adhesive Expert Insight: Why Food-Contact Appliances Need True “Food-Contact Adhesives”
In modern household appliances such as smart tea makers, health kettles, water dispensers and insulated cups, components that come into contact with drinking water, steam and hot liquids must meet strict requirements: food safety, high-temperature resistance, waterproof sealing, multi-material compatibility and clear appearance.
As the Odake Adhesive Experts, we developed CT775A Food-Contact Adhesive — a clear silicone glue / silicone sealant engineered specifically for food-contact applications. It combines food-grade safety, strong bonding performance and long-term durability, and has fully passed customer validation tests.
1. Food-Contact Safety: Truly Meets FDA Requirements
From the beginning, Odake CT775A was designed as an adhesive suitable for drinking-water pathways.
Key advantages include:
Food-grade silicone formulation
Alcohol-release curing system: non-corrosive and non-toxic
Formulation aligned with FDA food-contact safety requirements
Low odor, solvent-free, compliant with ROHS/REACH/VOC regulations
Ideal for:
glass parts in tea makers, silicone tubing in water dispensers, glass pot sealing, insulated cup lid gaskets, ceramic components in tea ware and more.
2. Multi-Material Compatibility: True Engineering-Level Bonding
Based on customer test feedback, CT775A successfully achieved strong bonding in the following combinations:
Glass ↔ PC
Glass ↔ Stainless steel
Silicone tubing ↔ Silicone tubing
Sealing ring ↔ Stainless steel
Ceramic ↔ Ceramic
The high-performance silicone system of CT775A allows it to bond both rigid smooth materials (glass, stainless steel) and flexible substrates (silicone), making it ideal for complex food-contact appliance structures.
3. Temperature Resistance: Continuous 100°C, Peak up to 235°C
According to TDS data, CT775A features a wide operating temperature range of -60°C to 235°C.
Engineers will appreciate its stability under conditions such as:
Hot-water sections inside tea makers
Sealing zones at the bottom of health kettles
Silicone tubing joints in drinking-water systems
Insulated cup lid seals
CT775A maintains flexibility without cracking or delamination, and resists yellowing even under long-term heat.
4. Waterproof Sealing Performance: Designed for IPX Protection
As a silicone sealant, CT775A cures into a flexible elastomer that provides:
Long-term waterproof and immersion resistance
Reliable adhesion under hot–cold cycling
Clear, non-yellowing appearance
Smooth dispensing with minimal bubbles and low shrinkage
These characteristics are essential for appliances that require IPX waterproof ratings or long-term liquid exposure.
5. Real Engineering Parameters (from TDS) Demonstrate Reliability
Viscosity: 15,000–20,000 CPS (high viscosity, non-sag)
Shore A hardness: 18–28
Tensile strength: ≥1 MPa
Elongation at break: ≥200% (absorbs vibration and impact)
Tack-free time: 10–15 minutes
Full cure: 24 hours
Excellent insulation: ≥1×10¹⁴ Ω·cm (safe for components near electrical circuits)
These specifications allow CT775A to achieve a balanced performance between bonding strength, flexibility and long-term sealing stability.
The Most Trusted Adhesive for Food-Contact Appliance Manufacturing
If you are looking for:
A true food-contact adhesive
An adhesive that meets FDA safety standards for drinking-water paths
A clear, high-temperature silicone glue that resists steam, heat and yellowing
A durable silicone sealant with both structural bonding and waterproof sealing performance
Then Odake CT775A is the professional solution engineered specifically for food-contact home appliances.
