Application of silicon adhesive sealant | Sealing of slip ring motor welding plate and lead wire sealing

Slip ring motors are widely used in automation equipment, wind power generation, medical instruments, and other fields. Their stable operation relies on efficient solder plate sealing and lead wire sealing. The selection of sealing materials is crucial as motors are subjected to high temperatures during operation and may be affected by external environments such as dust, moisture, and vibration. Therefore, it is important to select the right sealing material. customer demandA certain motor manufacturer encountered the following technical challenges while producing slip ring motors:Sealing requirements: Ensure the reliability of welding plate sealing and lead sealing, prevent external pollutants from entering, and ensure long-term stable operation of the motor.High temperature resistance: The temperature of the motor may reach 150 ℃ during operation, so the sealing material needs to have excellent temperature resistance.Curing speed: Production efficiency requires the sealant to cure quickly to improve assembly efficiency.Suitable viscosity range: The sealant needs to have moderate fluidity, be easy to apply, and not sag.Solution Sealing of welding plates and sealing of leads for slip ring motorsFor the needs of this customer, we recommend using BaiGao SIPC 1821 (black, viscosity 25000 CPS) or SIPC 1823 (white, viscosity 35000 CPS) silicone adhesive sealant. These two products have the following advantages:RTV SIPC 1821 neutral dealcoholized silicone adhesive sealant is a flowable moisture absorbing cured silicone gel that forms a flexible rubber body after curing, fully complying with the EU ROHS directive requirements. During the curing process, alcohol substances are released, which are non corrosive to materials such as polycarbonate (PC) and copper. RTV SIPC 1821 silicone adhesive sealant has good bonding and sealing properties for the vast majority of materials. The cured elastomer has the following characteristics:▶ Single component, easy to use, short non stick time▶ Excellent chemical resistance▶ Resist moisture, dirt, and other atmospheric components▶ Reduce…
