Brussels, October 31, 2013 ---Solvay announces today the closing of the acquisition of privately-held Chemlogics, following clearance from the relevant anti-trust authorities.

This acquisition, as part of the Group's transformation towards an innovative chemical solutions provider, enables Solvay’s Novecare business unit to become a leader with an extensive portfolio of tailored chemical solutions for the fast-growing oil & gas market.
