Epoxy-resin system resists high temperatures
Cures to a tough, strong solid with excellent long term durability and chemical resistance even when exposed to adverse environmental conditions.
The Master Bond Polymer System EP40 has been found to provide an excellent solution for applications requiring the inherently attractive strength properties of epoxy resins together with enhanced flexibility and peel strength characteristics.
Additional desirable performance characteristics of this unique epoxy compound include superior resistance to thermal cycling and mechanical vibration and shock.
Electrical insulation properties are excellent even after prolonged exposure to hostile environmental conditions.
The Master Bond Polymer System EP40's low viscosity facilitates bonding, sealing, casting and other processing operations.
The availability of versatile cure schedules further simplifies the application of this unique polymer compound.
The excellent adhesion of EP40 to a wide variety of substrates ranging from engineering plastics such as polycarbonates, acrylics and ABS to steel, aluminium and other metals is particularly noteworthy.
Thus shear and peel strength for bonding polycarbonates are in the order of 6.9MPa and 35N/cm, respectively while steel and aluminium bonds yielded shear strength values as high as 12.4 and 10.3MPa, respectively.
Master Bond polymer System EP40 has an impressively wide service temperature range of -70 to +110C.
The Master Bond EP40 compound is the preferred choice for many electronic potting and encapsulation applications, two component adhesives and sealants, coatings and composite uses wherever substrates with different thermal expansion properties must be combined to form electronic and/or mechanical assemblies.
