- Applications
- For potting, encapsulating and coating of modules, relays, and a variety of AC/DC converters including high power and planar packages
- Provides protection from moisture, dust and contaminants
- Increases resistance to shock and vibration
- Low viscosity allows the potting of complex geometries without the entrapment of air
- Pot life is compatible with processes that require dispensing or coating with Part A and B combined
- Dielectric properties compatible with many devices and increase breakdown voltage of device
- Instructions for Use
Mixing and Vacuum Deaeration
Combine Part A and Part B in a 1:1 mix ratio prior to use. Airless mixing, metering or dispensing equipment is recommended for production operations. If mixing by hand, take care to minimize air entrapment and check the work time prior to mixing and dispensing. Remove air entrapped during mixing by common vacuum deaeration procedure, observing all applicable safety precautions. Slowly apply full vacuum to a suitable container of at least four times the volume of material being de-aired. Hold vacuum until bulk deaeration is complete.
Substrate Considerations
R-2188 cures in contact with most materials common to electronic assembles. Exceptions include butyl and chlorinated rubbers, some Tin condensation cure silicones and unreacted residues of some curing agents. Units being encapsulated or potted should be clean and free of surface contaminates. Containers and dispensers being used should also be clean and dry. Cure inhibition can usually be prevented by washing all containers with solvent or volatizing the contaminant by heating.
