Conformal coating processes require precise masking of connectors, contact areas, and other components that must remain uncoated. Standard masking tape and generic boots often fail to provide a consistent seal around complex connector housings, leading to coating bleed onto contact pins or residue on mating surfaces after removal.

Our custom silicone masking boots are moulded to the exact profile of your connector or component, providing a secure, repeatable fit that maintains its seal through selective coating machines, spray booths, and dipping processes.

All custom boots are produced with a smooth inner surface to ensure consistent sealing against the masked connector housing. The silicone material is chemically resistant to the solvents and coating materials used in standard conformal coating processes.

Key properties and configurations:

• Process-compatible: suitable for acrylic, polyurethane, epoxy, and silicone conformal coatings, as well as wave and selective soldering processes
• Customisable hardness: Shore hardness selectable to match the retention and sealing requirements of each connector geometry
• Any connector profile: rectangular, circular, multi-row, and complex connector housings all available to drawing or sample
• Reusable and durable: high-quality silicone construction supports repeated use across multiple coating cycles without loss of fit or sealing performance
• Colour-coded to specification: any silicone colour available to support operator identification on the production line
• Economical for small series: custom tooling is viable even for smaller quantities where no standard masking boot provides a reliable fit for your connector

Lead time is typically 3 to 4 weeks from approved geometry.
