SYLGARD™ 170 Silicone Elastomer Kit is a two-part, room-temperature curing silicone system developed for potting, encapsulation, and protection of electronic components. It offers thermal stability, flexibility, and environmental resistance, making it suitable for high-reliability applications in demanding environments.
The kit consists of:
Part A (Base)
Part B (Curing Agent)
It cures to a soft, resilient rubber when mixed in the proper ratio, typically 1:1 by weight or volume.
Key Features
Room-Temperature Cure: No need for ovens or elevated temperatures.
Low Viscosity: Easy to mix and pour, even into tight cavities.
Excellent Dielectric Properties: Insulates and protects electrical components.
Thermal Stability: Operates effectively across a wide temperature range (typically -55°C to +200°C).
Flexible After Cure: Maintains mechanical properties under thermal and mechanical stress.
Good Adhesion: Bonds to a variety of substrates including metals, plastics, and ceramics.
Low Exotherm: Suitable for large-volume potting without thermal degradation.
UL Recognition: Often recognized for flammability and dielectric strength (check specific version certification).
Applications
SYLGARD™ 170 is widely used in:
Electronics Potting & Encapsulation:
Printed circuit boards (PCBs)
Sensors
Transformers
Connectors
Power Modules: Insulates and protects power electronics from moisture and contaminants.
LED Modules: Used to protect components while maintaining flexibility.
Automotive Electronics: Engine control units, battery protection systems.
Telecommunications: Component encapsulation in base stations and signal units.
Aerospace & Defense: Protects sensitive components from vibration, shock, and temperature extremes.
Safety & Handling
Safe Handling
Handle in well-ventilated areas.
Prevent contact with skin, eyes, and clothing.
Avoid breathing vapors or mists.
Personal Protective Equipment (PPE)
Gloves: Chemical-resistant (nitrile recommended)
Eye Protection: Safety glasses or splash goggles
Respiratory: If ventilation is inadequate, use an approved respirator
Storage
Store in a cool, dry place, ideally 15°C to 30°C (59°F to 86°F).
Keep containers tightly closed to avoid moisture contamination.
Shelf life: Typically 12 months from manufacture date.
First Aid Measures
Eye contact: Rinse cautiously with water for 15 minutes. Seek medical attention.
Skin contact: Wash with soap and water. Remove contaminated clothing.
Inhalation: Move to fresh air. Seek medical help if symptoms develop.
Ingestion: Do not induce vomiting. Rinse mouth and seek medical help.
Disposal
Dispose in accordance with local, regional, and national regulations.
Cured material is typically non-hazardous and may be treated as solid waste.
Uncured material may be flammable or hazardous – dispose accordingly.
