LONDON (ICIS)--South Korea-based Songwon Industrial Group is expanding its DOTO (di-n-octyltin oxide) production capacity at its Ulsan manufacturing facility by 60%, the producer said on Friday.

DOTO is an organotin intermediate, which can be used as a raw material in the production of heat stabilisers and glass coatings.

The project is expected to be completed by mid-2013. Capacity and financial details of the expansion were not disclosed.

Songwon said the new DOTO capacity will come at the expense of a reduction in DBTO (di-n-butyltin oxide) capacity.

The company added that beyond the current project, it is planning additional DOTO capacity to support future market needs.

Songwon said that as a result of the EU’s Reach chemicals control legislation, the movement to replace butyltin compounds is accelerating, especially in the European market. The company foresees that where possible, butyltin compounds will be replaced by octyltin compounds by 2015.

KT Jeong, Songwon’s business manager of PVC Stabilisers and Tin Intermediates, said: “Our move to DOTO will ensure that we can provide the products that our customers need without compromising our environmental stewardship.”
