Potting, encapsulation, coating, sealing, impregnation compound. Meets NASA low outgassing specifications.
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. Fluids are broadly classified as: Newtonian Fluids and Non-Newtonian fluids.
Viscosity may be simply defined as the resistance to flow, of a liquid. 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. 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. 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.
