Product Overview​​
Dow Corning 3165 is a ​​non-flowing, one-part moisture-cure RTV (Room Temperature Vulcanizing) silicone adhesive sealant​​ designed for high-performance bonding and sealing applications in electronics and industrial manufacturing. Known for its rapid tack-free cure at room temperature and exceptional flame resistance, this adhesive eliminates the need for mixing or ovens, streamlining production workflows. Its UL 94V-0 flammability rating and strong initial adhesion make it ideal for demanding environments where safety and reliability are critical.

Product Introduction​​
Dow Corning 3165 is a versatile silicone adhesive engineered to provide fast, reliable bonding for a wide range of materials, including metals, ceramics, glass, and select plastics. Its unique formulation allows for ​​immediate handling strength within 5 minutes at 25°C​​, reducing production downtime. The adhesive cures through exposure to atmospheric moisture, achieving full physical properties in 24–72 hours (accelerated by mild heat if needed). With a shelf life of 12 months when stored properly, it offers long-term stability and ease of use. Applications span from sealing electrical enclosures and wire harnesses to reinforcing components on printed circuit boards (PCBs).

Special Attributes​​

​​Rapid Curing​​: Achieves tack-free status in just 5 minutes at room temperature, enabling faster assembly cycles.

Enhanced Flame Resistance​​: UL 94V-0 certification ensures compliance with strict fire safety standards, making it suitable for automotive, aerospace, and consumer electronics.

​Mechanical Stability​​: Delivers 125 psi (0.9 MPa) tensile strength and a Shore A hardness of 35, balancing flexibility and durability.

​​Low-Temperature Flexibility​​: Maintains performance from -45°C to 200°C (-49°F to 392°F), resisting thermal cycling and vibration.


Application Scenarios​​
While specific case studies for Dow Corning 3165 are proprietary, typical use cases include:

​​Sealing Electronic Modules​​: Protecting sensitive components from dust, moisture, and thermal stress in automotive ECUs, industrial controllers, and IoT devices.

​​PCB Assembly​​: Bonding connectors, capacitors, and other components while withstanding mechanical shock and vibration.

​​Wire Harness Sealing​​: Insulating and securing wired connections in harsh environments (e.g., marine, oilfield equipment).

​​Consumer Electronics​​: Encapsulating speakers, sensors, and buttons in smartphones, wearables, and home appliances.
