- the invention relates to two-component epoxy resin systems which are cured by cold curing and which have high glass transition temperatures without subsequent tempering.
- the first component comprises at least one epoxy resin
- the second component comprises a hardener.
- the epoxy resin and hardener react with one another, causing crosslinking.
- Hardeners based on amines are widely used. However, the properties of a hardened epoxy resin depend very much on the selection of the amines used, the application temperature and the hardening temperature.
- Epoxy resin systems are widely used to achieve rigid bonds. Such bonds are often structural bonds.
- the area of application of composites that have such bonds is very diverse and includes very different temperature ranges.
- the glass transition temperature of the adhesive is an extremely important factor, particularly for use at high temperatures. If the glass transition temperature is exceeded, the adhesive changes its properties significantly, which means that secure and long-term bonding cannot be guaranteed.
- the glass transition temperature can be increased by subsequent tempering at many epoxy resin adhesives applied at room temperature or slightly elevated temperatures.
- an epoxy resin adhesive is applied at room temperature and, after reaching a certain early strength, is stored overnight or for a few days in a boiler room at temperatures of, for example, 100 ° C.
- cold-curing adhesives are increasingly required which, after mixing, application and curing, have a high glass transition temperature at room temperature or slightly elevated temperatures.
