Isolatsioonimasse

Isolatsioonimasse, often translated as insulating compound or potting compound, refers to a material used to protect, seal, and electrically insulate electronic components or assemblies. These materials are typically viscous liquids or semi-liquids that cure to form a solid, protective coating. The primary function of isolatsioonimasse is to provide environmental protection against moisture, dust, chemicals, and physical damage. They also serve to hold components in place, reduce vibration, and prevent unwanted electrical discharge or arcing by filling voids and ensuring uniform dielectric properties.

The selection of an isolatsioonimasse depends on the specific application requirements, including operating temperature, chemical resistance, electrical insulation properties, adhesion to substrates, and curing mechanism. Common types of isolatsioonimasse include epoxy resins, silicones, polyurethanes, and acrylics. Each type offers a distinct balance of properties. For instance, silicones are known for their flexibility and wide operating temperature range, while epoxies provide excellent chemical resistance and mechanical strength. The application method can vary from simple pouring and brushing to more complex dispensing systems for automated manufacturing. Once applied, the isolatsioonimasse undergoes a curing process, which can be initiated by heat, UV light, or a two-part chemical reaction, transforming it into a solid protective layer.
