- Expanding Electronic Void Fill
- Assembly-Conforming Foam Packaging
Product Description
CONATHANE UF-3 Polyurethane Foam is a room-temperature-curing polyurethane foam for packaging electronic components and assemblies. After mixing, the material expands to fill available void spaces around protected hardware, creating a foam-format packaging layer within the assembly. This expansion behavior supports coverage of available cavities and void spaces during cure. UF-3 is suited to electronic packaging and void-filling operations where a two-component expanding polyurethane system is required to occupy open space and cure around components at room temperature.
Key features
- Expanding Void Fill: The polyurethane system expands during cure to occupy available spaces around hardware.
- Room-Temperature Cure: UF-3 develops its foam structure through an ambient cure process.
- Electronic Packaging Use: The product is intended for packaging components and complete electronic assemblies.
Applications / Suitable for
- Packaging electronic components
- Protecting electronic assemblies
- Filling void spaces around hardware
