High strength methacrylate ester acrylic retaining compound designed for the bonding of cylindrical fitting parts.
LOCTITE® 609 is a green, high strength methacrylate ester acrylic retaining compound designed for the bonding of cylindrical fitting parts. The product cures in the absence of air between close fitting metal surfaces. Typical applications include rotor to shafts in fractional and subfractional horsepower motors. Locks bushings and sleeves in housings on shafts. Augments press fits.
TYPICAL CURING PERFORMANCE
Recommended conditions for curing are exposure to heat above 100 °C (typically 90-120 seconds @ 150 °C). Rate of cure and final strength will depend on the residence time at the cure temperature.
Cure Speed vs. Time, Temperature
The following graph shows the rate of torque strength developed with time at different temperatures. These times are defined from the moment the adhesive reaches cure temperature. In practice, total oven time may be longer to allow for heat up period. Strength is measured on 1206 capacitors @ 22 °C, tested according to IPC SM817, TM-650 Method 2.4.42.
