Loctite 3090 Bonds Close-Fitting Parts In 20sec

Henkel Loctite Adhesives has launched Loctite 3090, a two-part cyanoacrylate that is said to significantly increase the versatility of instant adhesives. Along with the traditional benefits - an initial bond within seconds, clear bondline, high strength and easy dispensing - the product allows any exposed adhesive remaining outside of the joint to harden within 2-4min. The company said this additional advantage removes the need for a post-assembly activator and enables larger gap sizes to be readily accommodated.

Loctite 3090 will bond together close-fitting parts in 20sec; even where the gap is 3mm bonding is achieved in less than 90sec. The product can also be used where a more significant gap - up to 5mm - is involved. Loctite 3090, which can be used on a variety of substrates, including plastic, rubber, wood, stone, leather, fabric or metal, is capable of withstanding a force of 20N/mm2.

Application is said to be very easy, with the adhesive available in a pack containing a dual syringe with seven mixer nozzles. These syringes ensure a clean application and also that the correct ratio of each component is always applied. Furthermore, its gel viscosity means the adhesive can be used for vertical or overhead application. The temperature range of the two-part CA is versatile - it can be used between -20C to +80C.

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.
