Epoxy Polymer
Epoxy resins are a family of monomelic or oligomeric material that can be further reacted to form thermoset polymers possessing a high degree of chemical and solvent resistance, outstanding adhesion to a broad range of substrates, a low order of shrinkage on cure, impact resistance, flexibility, and good electrical properties.
Epoxy resins have found a broad range of application, mainly because the proper selection of resin, modifiers, and cross-linking agent allows the properties of the cured epoxy resin to be tailored to achieve specific performance characteristics. This versatility has been a major factor in the steady growth rate of epoxy resins over the years.
Besides this versatility feature, properly cured epoxy resins have other attributes :
- Excellent chemical resistance, particularly to alkaline environments.
- Outstanding adhesion to a variety of substrates.
- Very high tensile, compressive, and flexural strengths.
- Low shrinkage on cure.
- Excellent electrical insulation properties and retention thereof on aging or exposure to difficult environments.
- Remarkable resistance to corrosion.
- A high degree of resistance to physical abuse.
- Ability to cure over a wide range of temperatures.
- Superior fatigue strength.
