Master Bond Supreme 10AOHT
As a one component adhesive, Supreme 10AOHT offers a convenient no mix formulation, as well as rapid elevated temperatures cures. Typically, the system cures in just 1 hour at 250-300°F. Supreme 10AOHT has a smooth paste consistency, making it easy to apply with a spatula, knife, trowel, brush or paint roller. It is 100% reactive and does not contain any diluents or solvents, so shrinkage upon cure is minimal.
In addition to high strength bonds and easy handling, Master Bond Supreme 10AOHT has superior resistance to severe thermal cycling, impact, thermal shock, vibration and stress fatigue cracking while maintaining the moisture, creep, corrosion and thermal resistance typical of epoxy resin adhesives. This toughened adhesive can also withstand chemicals including water, oil, fuels and most organic solvents even upon prolonged exposures. Its adhesion to metals, glass, ceramics, wood, vulcanized rubbers and many plastics is excellent.
Serviceable in cryogenic conditions and extreme heat up to 400°F, Supreme 10AOHT delivers outstanding performance across a wide range of industries, such as aerospace, electronic, electrical, computer, metalworking, appliance, automotive and chemical processing.
Thixotropic Polymer Systems
Fluids can be categorized as Newtonian and non-Newtonian. The viscosity of the Newtonian fluids remains constant at all shear rates at a constant temperature and pressure. But, for a non-Newtonian fluid, the viscosity varies with the shear rate and time. Thixotropic epoxies are non-Newtonian fluids which are gel-like at rest, but tend to flow when agitated or stressed. The particles of this type of product are held together by weak forces at low shear rates, whereas at high shear rates the particles tend to separate.

The viscosity for thixotropic materials can be measured at different shear rates using a viscometer. Using this data, the viscosity associated with a particular spindle shape and RPM can be obtained.
Master Bond offers many epoxies which exhibit thixotropy. These epoxies are used widely as adhesives and sealants in applications where non-drip and high viscosity characteristics are desirable. Both one component heat curing systems and two component room-temperature curing systems are available under the category of thixotropic adhesives. These adhesives also offer other properties like excellent electrical insulation properties, high thermal conductivity and resistance to high temperatures.
