Abstract
This disclosure relates to epoxy compositions and more particularly to two-part epoxy compositions that are useful for marking substrates, such as roadway and airport runway surfaces. The compositions and methods described herein can reduce build-up on applicator pump seals. Such build-up can lead to pump failure. In some cases, the compositions can reduce down-time due to pump failure. However, the compositions retain the necessary properties for substrate marking, such as curing within a short period of time.
