DOWSIL™ CC-8030 UV and Dual Moisture Cure Conformal Coating Clear 18 KG

Product Overview

DOWSIL™ CC-8030 UV and Dual Moisture Cure Conformal Coating Clear is a 1-part, solventless, dual-cure silicone conformal coating engineered for rapid throughput in high-volume printed circuit board (PCB) assembly lines. It cures in seconds upon UV light exposure for immediate handling, while an uninhibited secondary moisture cure mechanism ensures complete cross-linking in unexposed shadow areas beneath electronic components. Featuring low viscosity, zero VOC emission, and a UV indicator for easy inspection, it delivers superior environmental sealing for automotive and industrial electronics. The 18 kg industrial pail format is designed for high-volume automated selective coating machines and fluid dispensing lines.

Key Features and Benefits

• Dual-Cure Technology: Rapid UV cure in seconds for fast processing, complemented by ambient moisture cure for hidden shadow areas.
• Industrial Bulk Packaging (18 KG): Suited for continuous automated selective coating equipment and high-volume production lines.
• Solventless & Environmentally Friendly: Contains no solvents or harmful VOCs, promoting workplace safety and compliance.
• UV Indicator: Fluoresces under blacklight for easy automated optical inspection (AOI) of coating coverage and film quality.
• Flexible Elastomeric Protection: Stress-relieving silicone film absorbs thermal expansion cycling and mechanical vibration.
• Robust Environmental Barrier: High moisture resistance protecting circuit traces against humidity, corrosion, and dirt.

Technical Specifications

• Appearance / Color: Clear / Transparent (UV fluorescing)
• Packaging / Net Weight: Pail / 18 KG
• Chemical Base: 1-Part Solventless Silicone (UV / Moisture Cure)
• Viscosity (@ 25°C): ~70-120 mPa.s
• Primary Cure: UV Light (Seconds)
• Secondary Cure: Ambient Moisture (RTV for shadow areas)
• Service Temperature Range: -45°C to +150°C (-49°F to +302°F)

Applications

• High-volume conformal coating of automotive electronics, instrument clusters, sensors, and body control units.
• Bulk moisture-proofing for consumer electronics, smart home devices, and industrial control cards.
• Protection of LED driver circuitry, power supplies, and telecommunication modules.
• Automated high-speed selective coating and spray dispensing operations.

Usage Note: Substrates must be clean and free of flux residue, oil, and moisture before application. Protect light-sensitive bulk pails and supply lines from direct daylight exposure. Low viscosity allows smooth processing through automated selective coating machinery or spray valves. Assemblies can be handled immediately post-UV exposure, while shadow areas achieve full cure within days via room moisture.
