Speed Up Conformal Coating & Prevent Shadow Areas with the UV Cure DOWSIL™ CC 8000 Series
Conformal coatings are essential for protecting PCBs from moisture and environmental stress, reducing corrosion, and improving reliability. To address the growing need for faster manufacturing and more reliable protection, Dow, a leading supplier of silicone based materials, has introduced the DOWSIL™ CC 8000 Series UV & Dual Moisture Cure Conformal Coatings.
These silicone-based coatings cure in seconds with broad spectrum UV or LED light, solve issues with shadow areas through a secondary moisture cure, and span the range of low-to-high viscosities, providing electronics manufacturers with a complete range of options for strong PCB protection.
1. Why Electronic Manufacturers are Shifting to UV Conformal Coatings
Traditional room temperature or heat cure coatings deliver protection, but often require long cure times, additional handling, or curing ovens, which can limit production efficiency. In contrast, UV conformal coatings cure on demand, allowing manufacturers to handle boards within seconds rather than hours.
This faster cure capability helps manufacturers:
• Reduce work in progress
• Improve line efficiency
Since modern PCB assemblies include connectors, pins, and other dense components that can block light and cause “shadow areas”. Dual cure conformal coatings provide a more complete solution, combining rapid UV cure with a secondary room temperature curing process.
Ellsworth has over 200+ experts around the world and a close relationship with Dow, giving PCB manufacturers complete support for the CC-8000 series. Contact a Glue Doctor® from Ellsworth to specify the right coating for your application, implement the right UV curing and dispensing equipment, and keep materials in-stock when they’re needed on the line.
