FM Dowcorning Dowsil 732 Sealant 300ml FDA Food Grade Sealant RTV Gasket Neutral Silicon Sealant

Dow Corning 732 is a high-performance silicone sealant designed for demanding applications across industries. Below is a structured breakdown of its key uses, features, and benefits based on the provided information:

Key Features

• Waterproof & Dustproof: Creates durable seals to protect against moisture, humidity, and contaminants.

• Thermal Stability: Resists extreme temperatures (commonly -50°C to +200°C for similar silicones).

• Electrical Insulation: Safe for use in electronic components due to non-conductive properties.

• Chemical Resistance: Withstands exposure to fuels, oils, and environmental stressors.

• Flexibility: Maintains adhesion under vibration or movement (critical for automotive and aerospace).

• UV Resistance: Suitable for outdoor/solar applications.

Primary Applications

1. Electronics & Electrical Equipment

• Seals circuit boards, connectors, and sensors.

• Protects against moisture, dust, and short circuits.

2. Automotive Industry

• Seals engine components (e.g., spark plug gaskets, O-rings).

• Resists oil, fuel, and high-temperature environments.

3. Industrial Manufacturing

• Seals pipe joints, flanges, pumps, and valves to prevent leaks.

• Ideal for chemical processing or hydraulic systems.

4. Lighting Equipment

• Waterproofs lamp housings and protects bulbs/electronics.

5. Household Appliances

• Seals refrigerators, air conditioners, and washing machines.

6. Aerospace

• Bonds and seals aircraft components exposed to extreme pressure/temperature.

7. Solar Equipment

• Seals solar panel edges and junction boxes against weather damage.

8. Communication Systems

• Protects base stations, antennas, and outdoor telecom equipment.

Benefits

• Versatility: Compatible with metals, plastics, glass, ceramics, and most substrates.

• Durability: Long-lasting performance in harsh environments (UV, humidity, chemicals).

• Safety: Non-corrosive and electrically insulating for sensitive electronics.

• Ease of Application: Typically cures at room temperature (RTV silicone).

Technical Considerations (Typical for Silicone Sealants)

• Cure Time: 24 hours (full cure, depending on thickness and humidity).

• Shore Hardness: ~25–35 Shore A (flexible yet durable).

• Color: Clear or translucent (common for electronics/aesthetic applications).

• Certifications: Likely meets UL, RoHS, or industry-specific standards.

Limitations

• Not for High-Pressure Systems: Best for static or low-pressure seals.

• Surface Preparation Required: Substrates must be clean and dry for optimal adhesion.

• Temperature Limits: Verify exact operating range from datasheet (varies by formulation).

Why Choose Dow Corning 732?

• Reliability: Trusted brand for industrial and electronic applications.

• Multi-Industry Use: Reduces inventory needs by serving diverse sectors.

• Long-Term Protection: Extends equipment lifespan in harsh conditions.

Ideal For: Engineers, manufacturers, or maintenance teams needing a robust, flexible sealant for critical applications. Always consult the product datasheet for precise specifications and compatibility.
