Encapsulating adhesive is primarily used to seal and secure critical components in kitchen appliances, such as motors, electronic modules, and circuit boards. Its main functions include:
1. Waterproof and Moisture-Resistant: The potting compound effectively repels water and prevents moisture from seeping in, ensuring that home appliances function properly even in humid environments.
2. Insulation Protection: Encapsulating adhesive boasts excellent insulation properties, safeguarding electrical components from safety hazards such as current leakage and short circuits.
3. Shock and noise reduction: Potting compounds can absorb vibrations and noise, enhancing the stability of home appliances during operation.
4. Heat Dissipation: Some potting compounds exhibit excellent thermal conductivity, helping to dissipate heat from electrical components and enhancing overall performance.
Specific recommendations for kitchen appliance potting compounds
1. Soy milk maker and high-speed blender control modules
Recommended ： HNSIL 8730 Silicone Potting Compound
Reason : Soft and highly elastic, waterproof and moisture-resistant, cures quickly, and protects delicate circuits.
2. Microwave oven and oven high-temperature components
Recommended ： Hinnel HNSIL 703 Deoxime-type organosilicon sealant
Reason : Temperature resistance up to 300℃ , resistant to thermal cycling and exhibits excellent long-term stability.
3. Juicer cup lid sealing, soy milk maker heating tube protection
Recommended: HNSIL 770 Silicone Sealant
Reason: Eco-friendly, food-grade certified, semi-flowing paste-like texture—non-drip and ideal for housing sealing.
4. Microwave oven magnetron cooling, coffee machine heating module
Recommended: HNSIL 717 Organic Silicone Thermal Conductive Adhesive
Reason: Thermal conductivity 1.2 W/m·K , excellent adhesion, good insulation performance, and extended service life.
Common Problem Solutions
✅ Leak-proof and watertight : Choose high-elasticity silicone rubber.
✅ Panel Detachment : Switch to acrylic foam tape or silicone adhesive instead of mechanical fasteners.
✅ Unusual Noise and Vibration : Add polyurethane damping rubber to the motor base.
✅ Poor heat dissipation : Replace with high-thermal-conductivity thermal grease.
