Connecticut-based additives major Chemtura Corp reported a net loss of US$278 million for the second quarter of 2008 on net sales of $1.023 billion. In second quarter 2007, the company achieved a net profit of $8 million on sales of $1.038 billion. The decrease in revenues was attributed to the impact of divestitures and lower volume and product mix, partially offset by favourable currency effects and higher selling prices.
For the first six months of 2008, Clariant posted net sales of CHF4.233 billion (c. €2.75 billion).
