AboCast 22-30 is a black filled resin with high viscosity and a weight of 12.4 lbs/gallon. AboCure 50-4 is clear, slow converter with a variable ratio, low viscosity, and a weight of 8 lbs/gallon. AboCast 22-30/AboCure 50-4 is a slow, thick, filled, black, opaque, room-temperature-cure, medium-viscosity epoxy system. It is the preferred system for most casting applications. It offers good thermal conductivity, minimum shrinkage, and low exotherm (heat of reaction). AboCure 50-4 can be mixed in ratios variable from 16 to 50 pbw with 100 pbw AboCast 22-30 for different cured properties: higher rigidity, chemical and heat resistance with the lower AboCure ratios (16-20 pbw), or higher flexibility with higher ratios. The converter offers the lower exotherm that permits unusually heat-sensitive or large castings. The system is used for encapsulation, potting, and assembly of electronic and magnetic components, such as: capacitors, transformers, terminals, industrial magnets, small and large magnetic assemblies, metal detectors, metal separators, magnetic printing cylinders, magnetic holders, insulators, junction boxes, switches, and circuit boards. It is also used in general-purpose casting and bonding for structural and dielectric applications. |
