DOWSIL™ CC-2588 Conformal Coating for Protection of Electronic Components

DOWSIL™ CC-2588 is a one-component, solvent-based silicone conformal coating produced by Dow. It appears as a clear/slightly cloudy liquid with a sweet odor. Its primary function is to be applied to electronic assemblies such as printed circuit boards (PCBs) to form a protective film that resists environmental factors like moisture, dust, chemicals, and stress.

Product Introduction

This product is applied by methods such as spraying, dipping, or brushing and cures at room temperature. According to the Safety Data Sheet (SDS), DOWSIL™ CC-2588 is a flammable liquid and harmful to aquatic life. It contains multiple components, including Petroleum, light alkylate naphtha (<10.0%) and Trimethoxymethylsilane (<9.0%). Safety precautions listed in the SDS must be strictly followed during use, including operation in well-ventilated areas, keeping away from heat sources and open flames, and wearing appropriate personal protective equipment such as chemical-resistant gloves and safety glasses.

Special Characteristics

DOWSIL™ CC-2588 possesses specific physical and hazardous properties. Its flash point (Seta closed cup) is 33°C, classifying it as a Flammable Liquid Category 3. It has a dynamic viscosity of 1,000 cP at 25°C, a relative density (water=1) of 0.97, and is insoluble in water. The product can cause mild skin irritation, and under fire conditions, its hazardous combustion products may include silicon oxides, formaldehyde, and carbon oxides. Therefore, for storage, containers must be kept tightly closed in a cool, well-ventilated place, and separated from incompatible materials such as oxidizers.

Application Scenarios

DOWSIL™ CC-2588 is designed to protect delicate electronic circuits and components, suitable for applications requiring resistance to harsh environments. The document confirms its use as a “coating." The document does not detail specific application scenarios, but based on my general knowledge of conformal coatings, typical applications for such products include automotive electronic control units (ECUs), industrial sensors, outdoor LED lighting drivers, and communication base station modules, providing them with moisture-proof, anti-corrosion, insulation, and dust-proof protection. Please note that the parameter table below is compiled exclusively based on the DOWSIL™ CC-2588 SDS document you provided, and does not include data from other models.
