As the supporting and heat‑dissipating backbone of the entire microwave oven, the base plate’s bonding process is of paramount importance. The base plate’s structural stability, electrical insulation, and thermal shock resistance directly influence the appliance’s performance. High‑quality bonding not only ensures product durability but also enhances overall performance and operational safety.
Recommended for use Hinnel HNSIL 703 Oxime‑type organosilicon adhesive sealant , neutral, low-odor, moisture-resistant and water-repellent; after curing, it exhibits excellent corrosion resistance and chemical resistance, maintains superior electrical insulation over the long term, and can withstand high temperatures up to 300 Degree, suitable for bonding and sealing microwave oven base plates.
Advantages of silicone sealant products:
1. High-strength adhesion: Hinnel’s adhesive boasts exceptional bonding strength, ensuring a tight seal between the baseplate and the housing, effectively preventing detachment and cracking.
2. Excellent temperature resistance: The adhesive maintains stable performance even under high-temperature conditions, ensuring the microwave’s safety across a wide range of operating environments.
3. Environmental safety: Hinnel’s adhesive is non-toxic and harmless, meets environmental standards, and provides a safe, eco-friendly solution for your production line.
4. Easy to operate: The adhesive boasts excellent application performance, is easy to spread, and helps save you time and labor costs.
Application method for silicone sealant:
Pre-processing: Clean the bottom surface of the microwave thoroughly, using a cleaning agent to remove rust, dust, grease, and other residues.
Sizing: Cut the nozzle to the required size and load it into the caulking gun. Extrude the adhesive onto the thoroughly cleaned surface, ensuring even distribution. For bonding, simply bring the surfaces to be joined together and hold them in place. At room temperature, 55 Under conditions of % relative humidity, the rubber compound exposed to air will, in approximately… 15 Complete in about minutes “ Crust ” Therefore, all processing steps must be completed before the skin forms.
Curing: After the rubber compound forms a skin, it continues to cure from the surface inward, in… 24 within hours ( At room temperature, 55 Under % relative humidity ) , the adhesive will cure in approximately 2-3mm The depth of cure. In extremely deep layers—particularly in areas where atmospheric moisture has difficulty penetrating—complete curing will take longer, and the curing time will be even extended under low-humidity conditions. When handling and packaging bonded components, users are advised to allow sufficient time to ensure that the adhesive seal remains unaffected. This depends on numerous factors, and for each specific application, it should be determined by the user.
Note: After use, any unused adhesive should be tightly sealed and stored. When reusing, if a thin skin has formed on the seal, simply remove it; this will not affect normal use.
The cracking of a microwave oven’s bottom plate may affect its normal operation. By selecting the appropriate adhesive and following proper installation procedures, you can ensure the microwave’s normal use and extend its service life.
