In the electronic manufacturing industry, the issue of switch leakage on PCB (printed circuit board) has always been a focus of attention for technicians. With the development of electronic products towards high density, miniaturization, and lightweight, higher requirements have been put forward for sealing materials: colloids are required to have characteristics such as “detachable”, “fast curing”, and “slight fluidity”. This article will share a real case to introduce how to use SIPC 1826 transparent silicone adhesive sealant (RTV 1826 alcohol free silicone adhesive sealant) to solve the problem of PCB switch leakage and achieve the best balance of electronic product protection.
Background and Challenges
On the production line, there is a slight leakage problem in the PCB switch area, which not only affects the appearance of the product, but also poses a hidden danger to the stability of subsequent use. Traditional sealants often have defects such as long curing time, insufficient adhesion strength, or difficulty in disassembly, which cannot meet the high-precision and high-efficiency electronic product manufacturing needs. Therefore, the manufacturer urgently needs a new type of silicone sealant that can cure quickly, be detachable, and have slight fluidity.

SIPC 1826 transparent silicone adhesive sealant (RTV 1826 dealcoholized silicone adhesive sealant) is a neutral curing silicone sealing material that can absorb moisture from the air at room temperature to complete curing. This product has the following major features:
Fast curing: The product has a fast drying speed and can form a protective film in a short period of time, significantly improving production efficiency.
Detachability: Due to the use of a small amount of adhesive application, it can be disassembled even after sealing, making it easy for later maintenance and repair work.
Slight fluidity: ensuring self adjustment after dispensing, filling small gaps without loss or diffusion, ensuring sealing effect while reducing
In summary, SIPC 1826 transparent silicone adhesive sealant provides a new solution and practical case for PCB switch leakage problems through its excellent performance, simple construction and maintenance advantages. In the future, we look forward to seeing more companies continuously innovating in sealing technology and jointly promoting the upgrading and progress of the electronic manufacturing industry.
