Dowsil 527 Silicone Gel Conductive Plastic For Electronic Equipment Coating

​​Product Overview​​
SYLGARD® 527 Silicone Dielectric Gel is a two-part, addition-cure system with a 1:1 mixing ratio. It is characterized by its low viscosity, room temperature or rapid heat cure capabilities, and self-healing properties. This gel is designed to provide long-term sealing against moisture and atmospheric contaminants, making it an excellent choice for applications requiring high purity and reliability.

​​Product Description​​
SYLGARD® 527 is a versatile silicone dielectric gel that cures to form a flexible, stable material capable of withstanding temperatures from -50°C to +200°C. It offers excellent dielectric properties and permanent pressure-sensitive adhesion to most materials without the need for a primer. The gel is purity tested, ensuring it meets stringent requirements for sensitive applications, particularly in the electronics industry.

​​Special Properties​​
One of the standout features of SYLGARD® 527 is its self-healing capability, which allows it to recover from minor mechanical damage, maintaining its sealing integrity over time. The gel also exhibits a low dissipation factor and high dielectric strength, making it suitable for electrical insulation applications. Its compatibility with a wide range of materials, combined with its ability to cure without by-products, ensures a clean and efficient application process. The gel's pot life of approximately 1.7 hours at room temperature provides ample time for application, while its rapid cure schedules allow for quick turnaround in manufacturing processes.

​​Application Scenarios​​
SYLGARD® 527 is commonly used for sealing and protecting delicate electronic circuits, hybrid devices, and small appliances. Its purity-tested formulation makes it particularly suitable for applications in the medical and aerospace industries, where high reliability and minimal contamination are critical. The gel is also used in the encapsulation of sensors and other electronic components that require long-term protection against moisture and environmental factors.
