Acrylic Acid capacity increase is an important milestone for Dow. We are excited to continue
investing in our European production footprint and about the opportunities generated by Dow’s
European customer base. Overall this is a valuable addition that reinforces Dow’s commitment to
growth for the region and further adds to our global footprint.”
