HumiSeal Acrylic Gel Conformal Coating

HumiSeal Acrylic Gel is a fast-drying, single-component acrylic paste engineered for precision and high-build protection. Its thixotropic nature means it stays in place upon application but flows under pressure, making it the perfect companion for standard acrylic conformal coatings. It provides a rugged barrier against moisture and environmental contaminants while remaining easy to rework.

Product Key Features

• Designed as a thick paste that will not slump or run, allowing for precise placement on vertical surfaces or specific components.
• Rapid evaporation of solvents speeds up production throughput and allows for quicker handling of assemblies.
• Easily removed with solvents or a soldering iron, making it ideal for boards requiring field service.

Applications

• Used to create a physical perimeter (a "dam") on a PCB to prevent liquid conformal coatings from flowing into restricted areas like connectors or test points.
• Effectively seals the base of large components to prevent moisture ingress or "wicking" underneath parts.
