Epoxy Combines Polymeric and Inorganic Materials

Master Bond's EP30LTE-LO two-component epoxy is designed for bonding, sealing, casting and coating applications in the aerospace, electrical, electronic, chemical, optical and computer industries. Formulated with a special blend of polymeric and inorganic materials, the EP30LTE-LO is claimed to provide excellent dimensional stability. This epoxy combines excellent performance with a low thermal expansion coefficient.

Serviceable over a temperature range of -60F to 250F, the EP30LTE-LO cures at room temperature with 85 per cent of its maximum strength developed within 48 hours. Faster cures are possible at elevated temperatures. This 100 per cent reactive epoxy features a low coefficient of thermal expansion of 12x10-6in/in/C and a low shrinkage rate of less than 0.0002in/in. It bonds well to metals, glass, ceramics, wood, vulcanised rubbers and most plastics and produces bonds with a tensile strength over 5,000psi.

This electrically insulative system resists thermal cycling and chemicals including water, fuels and many acids, bases, salts and organic solvents. It has a long working life of up to 60 minutes for a 200g mass. The EP30LTE-LO has a 10:1 mix ratio by weight and can be easily applied with a spatula, a knife, a trowel, a brush or a paint roller. It can also be readily cast as thick as 1in without undue exotherm developing. The EP30LTE-LO is available in half-pint, pint, quart, gallon and five-gallon container kits. This low outgassing epoxy features a low thermal expansion coefficient with solid electrical insulation properties.

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

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

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.
