Zirax plc ("Zirax" or the "Company"), the AIM quoted speciality chemical company focused on the development, production and sale of oilfield process chemicals and de-icing solutions is pleased to announce that it has won the contract to supply 15,000 Metric Tonnes (‘MT’) of calcium chloride based de-icers to Moscow City Council for its 2008/09 winter season.

This particular contract, worth $4.5m, means Zirax will supply its de-icing products to Moscow for a sixth consecutive year and places the Company in a strong position to win future contracts later this year to supply its value added de-icing product, IceMelt™.

Zirax’s de-icing products are more efficient, as they penetrate the ice quicker than most other de-icers, melting ice and snow at temperatures up to -35° Celsius, and better meets the environmental concerns of governments and local authorities, such as Moscow City Council, because of the significantly smaller quantities required to achieve better results.

Commenting on this announcement, Valery Andosov, Chief Executive of Zirax said:
“We are delighted that Moscow City Council has again chosen us to supply them with Zirax’s value added de-icers, which we believe places us in a strong position to win future contracts for renewal later this year. As we continue to grow our business in other areas, Moscow still remains an important account for Zirax and we look forward to continuing our working relationship with the council.”
