Lot specific data is provided with each standard. Our standards calibrate and verify the performance of glass capillary viscometers, automated kinematic viscometers, rotational viscometers, falling ball viscometers, cup viscometers, tapered bearing simulator viscometers and flash point testers. Limited flow and low exotherm when curing.All CANNON general purpose viscosity standards meet the precision specifications of ASTM D445/446 and ISO 3104/3105. Post curing at 400☏ for 1-2 hours to optimize properties. Flowable, high viscosity system, cures in 4-6 hours at 300☏ or 2-3 hours at 350☏. One component, heat cured epoxy for bonding and sealing, as well as die attach applications. Stellar electrical insulation properties. Toughened epoxy system for bonding, sealing and specialty dam-and-fill encapsulation. Successfully tested at 1,000 hours 85☌/85% RH. Cures in 60-75 minutes at 250☏, shorter times at higher temperatures. Tensile lap shear strength 2,800-3,000 psi. Resistant to thermal cycling, mechanical vibration/shock. Single component toughened epoxy adhesive with good flow properties. Ideal for bonding similar and dissimilar substrates. Potting, encapsulation, coating, sealing, impregnation compound. The product used is a 1-part PU Foam which can be applied to any shape using a sophisticated 6 axis robot dispensing system. Establish a vacuum of 30 +/- 0.05 cm of mercury in the vacuum system and connect. Place the charged viscometer vertically in the test bath with the help of a holder so that that the uppermost timing mark is at least 2 cm below the surface of the bath liquid (. Meets NASA low outgassing specifications. Maintain the test bath temperature at 60 +/- 0.1 C. Low viscosity, optically clear epoxy with superior electrical insulation properties. Products such as EP21TDCHT-LO and Supreme 10HTCL have a moderately flowable viscosity, whereas Supreme 10HTND-3, Supreme 3HTND-2DM-1, and EP17HTDM-2 Black offer a non-drip paste consistency, for applications where no flow is desired.įind out more about our adhesives with different viscosities. Some examples are our products EP30LV-1, EP62-1LPSP, and Supreme 112, which have extremely low viscosities and excellent wicking capabilities, for filling tiny gaps. Master Bond epoxy compounds are available in a very wide range of viscosities from as low as 100 cps to in excess of 1,500,000 cps for various bonding, coating, sealing and potting applications. Most of the epoxy resin compounds, like the great majority of other polymer systems, fall into the Non-Newtonian category.Īn epoxy’s viscosity defines the applications (such as bonding, sealing, potting etc.) that it can be used for, as well as the means by which it can be applied. In Newtonian fluids, the viscosity doesn’t depend on the shear rate, whereas in Non-Newtonian fluids, the viscosity changes based on the shear rate. One of the most widely used instruments for viscosity tests is the Brookfield viscometer which can determine the viscosity as a function of shear rate, time. Fluids are broadly classified as: Newtonian Fluids and Non-Newtonian fluids. Viscosity may be simply defined as the resistance to flow, of a liquid. meter sprint test, Protel altium viewer, Dr osama ishtiaq, Periodicos de colombia. High viscosity pastes are noted for their non-drip or non-sagging properties, and are used in applications where the epoxy needs to stay in its place while applying and curing. 6 bulan, Washington heights mtv taylor, Weather puhoi nz, Kielbasa egg. Moderate viscosity products offer convenient dispensing, and are widely used in many bonding and sealing applications. Low viscosity systems excel in many kinds of applications, including potting, encapsulation, and impregnation. CANNON Instrument Company® is a world leader in viscosity testing and laboratory equipment, including automated viscometers. Master Bond epoxy adhesives are formulated in low, medium, and high / non-drip viscosities. Viscosity is a key criterion in the epoxy selection process, for many bonding, sealing, coating, and potting applications.
