Impact-modified reaction resin

Abstract

The present invention comprises a novel formulation for marking trafficways, for example roads, which when compared with the prior art have improved mechanical properties and improved heat resistance during curing. The invention also relates to improved reactive resins for other applications than roadmarkings. The present invention in particular relates to reactive resins which comprise core-shell particles.
