73585976 - Dow 340 Thermal Grease 14 oz Cartridge

High-Performance Thermal Management

The Dow 340 Heat Sink Compound is a premium silicone-based thermal grease designed to provide efficient heat transfer between heat-generating components and heat sinks. Supplied in a substantial 14 oz container, this compound is an essential consumable for industrial maintenance, electronics repair, and facility management. Its grease-like consistency allows for easy application, filling the microscopic air gaps between mating surfaces to significantly lower thermal resistance and ensure optimal cooling performance.

Reliable Industrial Formulation

Formulated from silicone fluid thickened with metal oxide fillers, Dow 340 is engineered to maintain its consistency over a wide range of temperatures. Unlike lower-quality pastes that may dry out, crack, or harden over time, this compound exhibits low bleed and low evaporation characteristics. This stability ensures that the thermal interface remains intact for the service life of the equipment, reducing the need for frequent maintenance intervals. It is chemically inert and provides excellent resistance to oxidation, making it suitable for harsh industrial environments.

Versatile Applications

This heat sink compound is widely used across various industries for thermal coupling. It is particularly effective for mounting studs of transistors, diodes, and silicon-controlled rectifiers (SCRs). By facilitating the flow of heat away from sensitive electronic parts, it prevents overheating and prolongs the lifespan of critical machinery. Whether you are maintaining HVAC control systems, industrial power supplies, or general electronics, Dow 340 offers the reliability professionals demand.

Key Benefits

• Thermal Conductivity: Effectively bridges the gap between hot components and cooling surfaces.
• Stability: Retains grease-like properties without hardening or melting out of place.
• Electrical Insulation: Non-conductive nature prevents short circuits if applied near electrical leads.
• Economy Size: The 14 oz size is ideal for workshops and frequent users.
