Press Release Summary:
Used to insulate moisture-sensitive electrical components, including cartridge heaters and high power case resistors, Sil-Bond(TM) 905 demonstrates moisture resistance with weight gain of less than 1% after exposure to 900Â°F and 24 hours water immersion. Shrinkage rate is also less than 1% and dielectric strength is greater than 250 V/mil. Supplied as powder and liquid system, compound cures in 12-16 hr at room temperature and 30 min each at 150, 250, 350, and 450Â°F, respectively.
Original Press Release:
New Sil-Bond 905 High Temp Sealant Now Available
Valley Cottage, NY -
Sil-Bond(TM) 905, a new high temperature, ceramic-silicone potting compound developed by Aremco Products, Inc., is now used to encapsulate cartridge heaters and high power case resistors for applications to 900°F (482°C).
Sil-Bond(TM) 905 is an advanced, two-part, ceramic-silicone potting compound used to insulate moisture sensitive electrical components including cartridge heaters and high power case resistors for applications to 900°F (482°C). This compound demonstrates excellent moisture resistance with a weight gain of less than 1% after exposure to 900°F and 24 hours water immersion. A low shrinkage rate of less than 1% is also demonstrated after exposure to 900°F and the dielectric strength is greater than 250 volts/mil.
The combination of excellent electrical and moisture resistance make Sil-Bond(TM) 905 highly effective at stabilizing the electrical resistance values against changes induced by ambient conditions.
Sil-Bond(TM) 905 is supplied as a powder and liquid system that is mixed in a ratio of 100 parts powder to 50-60 parts liquid by weight. An extensive cure schedule is recommended to achieve best results. The cure schedule is 12-16 hours at room temperature and 30 minutes each at 150, 250, 350, and 450°F, respectively. Alternative cure schedules are possible depending on the area being encapsulated.
Sil-Bond(TM) 905 is supplied from stock in standard pint, quart, and gallon kits. For more information about this advanced, new product, please contact Aremco's Technical Sales Department.
