STONE HSR_products are additives for UV varnishes that increase the scratch resistance and the abrasion resistance of the varnish. They are compatible with existing formulations. For example, a reactive diluent is modified in that way it is significantly more scratch-resistant. The rheology of the treated substance increases slightly, the compatibility of these remains.
HSR_additives (high scratch resistance)
- Taber abrasion tests
- Crockmeter test
- the scratch resistance is increased with the components
- the flexibility is maintained
- the abrasion resistance is increased and detected with the taber abraser
- compatibility was obtained with the investigated formulations
