Epoxy Fits Structural Apps in Extreme Environments


Formulated for structural applications in extreme environments with temperatures from -80 to 425F, Master Bond Supreme 33 offers resistance to thermal cycling, thermal shock and impact. This toughened, two-component epoxy offers high structural bond strength to a variety of substrates, including metals, glass, ceramics, wood, vulcanised rubbers and many plastics. Supreme 33 also resists chemicals including water, oil and many organic solvents.

It has a mix ratio of 100 to 70 by weight or one to one by volume. It cures at room temperature in 48 to 72 hours. For optimal performance, the suggested schedule is curing overnight at room temperature followed by two to three hours at 150 to 200F. This 100-per-cent reactive epoxy does not contain any solvents or diluents, has high dimensional stability and features very low shrinkage upon cure. It produces high-performance bonds with a shear strength over 2,500psi, a tensile shear strength greater than 7,500psi and a T-peel strength exceeding 15psi.

With a volume resistivity of 1,014ohm-cm, a dielectric strength over 400V/ml and a dielectric constant of 3.8 at 75F, the Supreme 33 electrical insulator is suited for the electronic, electrical, aerospace and OEM industries. It is also available in a non-drip version called Supreme 33ND.

FUSE SIZING CONSIDERATIONS FOR HIGHER EFFICIENCY MOTORS

Image
When selecting the proper fuse for short circuit protection in motor starting applications, it is important to not only ensure that the fuse will not nuisance open during motor start up times, but also that the fuse will coordinate as required with overload relays. When sizing fuses between 125% and 150% of the motor nameplate current, several advantages, including ease of coordination with an overload device, a smaller disconnect, and increased short circuit protection from a lower fuse rating, can be achieved. However, if sizing at this level prevents the motor from starting, it may then be necessary to increase the fuse ampere rating and it then becomes important to know the NEC sizing limitations. As of June 1, 2016, the US Department of Energy has mandated that newly manufactured electric motors will need to meet NEMA Premium® efficiency standards. As motor efficiencies increase, motor locked rotor currents can also be expected to increase. In addition to this, with across-the-lin...

What is Class I Division 2?

Image
A Class I Division 2 is a location: (1) In which volatile flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are handled, processed, or used, but in which the liquids, vapors, or gases will normally be confined within closed containers or closed systems from which they can escape only in case of accidental rupture or breakdown of such containers or systems or in case of abnormal operation of equipment, or (2) In which ignitable concentrations of flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are normally prevented by positive mechanical ventilation, and which might become hazardous through failure or abnormal operation of the ventilating equipment. Class I Division 2 Classification Class I Division 2 refers to the ANSI/ISA 12.12.01 standard. This standard was previously UL1604 until UL recommended the newer ANSI/ISA standard be used and that all hazardous location products be certified under this standa...

7/8 16UN Connectors that Provide 600 Volts and 15 Amps

TURCK announces new A-Size 3 and 4-pin 7/8 16UN powerfast™ connectors that provide up to 600 Volts and 15 Amps of power. These IP67 rated connectors provide a modular wiring system designed to handle high current applications for machine power distribution, while providing resistance to vibration commonly associated with conveyors, motors and material handling applications. The cordsets are available with a tray rated, exposed run PVC flexlife ® cable, with or without STOOW rating, and 14 AWG wires that allow you to replace hard wiring with a robust, quick disconnect system that saves the time and money spent installing a conduit system. The A-Size powerfast line offers male and female, straight connectors, standard and custom lengths, and pigtails or extensions. To make the system complete, fully encapsulated mating receptacles, with 1/2”-14 NPT mounting threads are available.
