In the home appliance industry, microwave ovens are one of the daily kitchen equipment, and the stability and durability of their internal components directly affect the product’s service life and safety. Especially in the bonding process of the bottom plate of the microwave oven, it is required that the adhesive not only maintains a strong bond at high temperatures, but also adapts to the powder coating process on the surface of the microwave oven bottom plate.
Microwave oven bottom plate bonding
Case sharing
When producing microwave ovens, customers face a tricky bonding problem: the bottom plate of the microwave oven needs to be treated with powder coating technology to improve its surface hardness and wear resistance. But after powder coating treatment, the surface of the bottom plate is very irregular and prone to oil stains, which makes traditional adhesive glue unable to provide sufficient bonding force.
In addition, the internal temperature of the microwave oven is extremely high during use, and the bottom plate, as one of the supporting components, is exposed to high temperatures for a long time. The adhesive material must have strong high-temperature resistance. If the glue fails at high temperatures, it may cause the bottom plate to loosen or even fall off, affecting user safety.
Therefore, customers urgently need a glue that can solve the problem of insufficient adhesion of powder coated parts and withstand high temperatures, to ensure that the bottom plate of the microwave oven is always firm and reliable during long-term use.
Solution
After in-depth research and testing, ELAPLUS recommends using SIPC 1856, a black adhesive designed specifically for precision bonding in high-temperature environments. With a viscosity of 70000 CPS, it can provide strong adhesion on powder coated surfaces without sinking or deformation.
RTV 1856 alcohol free silicone adhesive sealant is a neutral silicone sealing material that absorbs moisture from the air and solidifies at room temperature. It has good adhesion and sealing performance for most plastic, metal and other materials, protecting electronic products in a stable state under harsh conditions. During the curing process, alcohol substances are released, which are non corrosive to materials such as polycarbonate (PC) and copper, and do not release irritating gases.
The elastic material cured with RTV 1856 silicone adhesive sealant for microwave oven bottom plate bonding has the following characteristics:
▶ Excellent chemical resistance and good adhesion
▶ Resist moisture, dirt, and other atmospheric components
▶ Reduce mechanical stress and tension caused by mechanical, thermal shock, and vibration
▶ Excellent outdoor aging resistance, with a service life of up to 20-30 years
▶ Seismic resistance, corona resistance, leakage resistance, excellent insulation performance
▶ Stable mechanical and electrical performance between -60-250 ℃
Actual application effect
In practical applications, after introducing SIPC 1856 into the microwave oven production line, the bonding effect of the bottom plate has been significantly improved by the customer. Even after working in a high-temperature environment for a long time, the bottom plate is still firm and not loose, and there is no sinking phenomenon on the bonding surface, perfectly solving the problems of irregular surface and insufficient bonding force after powder coating process.
Summary
The bonding of microwave oven bottom plate not only requires the adhesive to have good adhesion, but also to withstand the test of high temperature environment. SIPC 1856, with its outstanding performance, not only meets these high requirements, but also brings significant improvements to customers’ production processes. SIPC 1856 demonstrates excellent adhesion on powder coated surfaces and long-term stability against high temperatures, making it an ideal bonding solution for microwave oven manufacturers.
