ACC34 (Thinner for RTV sealants and Conformal Coatings)

DC Products provides a premium selection of silicone conformal coatings that safeguard delicate electronic components from moisture, dust, thermal stress, and chemicals. As an authorised distributor for Momentive Performance Materials (formerly GE Silicones) and CHT Silicones, we supply high-quality silicone coatings that are trusted within the electronics, automotive, aerospace, and industrial industries.

Our silicone conformal coating products are designed to retain flexibility and insulating qualities even in extreme temperatures, guaranteeing durability and consistent performance in challenging conditions.

How to Apply Conformal Coating Silicone?

Applying a conformal coating of silicone is a straightforward process that can be accomplished using various methods, depending on the production scale and precision requirements. Common application techniques include dipping, spraying, brushing, and selective robotic coating.

For high-volume manufacturing, automated dispensing systems ensure consistent, uniform coverage with minimal waste. For repair or low-volume applications, aerosol sprays or brush-on methods offer excellent control.

Most silicone conformal coatings cure at room temperature upon exposure to atmospheric moisture (condensation cure), while others are heat-activated (addition cure) for faster processing. A typical coating thickness ranges from 25–75 microns, providing optimal protection without adding stress to delicate components.

Ensure surfaces are clean, dry, and free of contaminants before application for maximum adhesion and performance.

Choosing the Right Conformal Coating Silicone for Your Needs

Selecting the correct conformal coating silicone depends on the specific requirements of your application. Key factors include:

Cure type (one-part condensation or two-part addition cure)
Viscosity (low for spraying, higher for brushing)
Thermal conductivity and operating temperature range
Regulatory compliance (e.g., UL, MIL-A-46106B, FDA, NSF)

At DC Products, we supply a wide range of conformal coating silicone materials, formulated to meet specific performance needs, including fast tack, low volatility, high purity, and optical clarity.

Our technical team can help you select the ideal product based on your process parameters, substrate type, and environmental conditions.

Environmental Resistance of Conformal Coating Silicone

Conformal coating silicone offers exceptional resistance to a wide range of environmental challenges:

Moisture and humidity – Prevents corrosion and short circuits
Thermal cycling – Remains flexible from -50°C to 250°C+
UV and ozone exposure – Resists degradation in outdoor applications
Vibration and mechanical stress – Provides stress relief for solder joints
Chemical exposure – Withstands solvents, fuels, and cleaning agents

These properties make conformal coating silicone an ideal choice for use in PCBs, LED assemblies, sensors, automotive ECUs, and industrial control systems, where long-term reliability is crucial.
