France: paints and coatings marketstagnated in 2003
French coatings manufacturersrecorded a slight downturn of0.3% in production volume(838,000 tonnes) in 2003. Salesof water based coatingsincreased by 2.8% to 45% of themarket volume. Powder coatingsrecorded a 10% downturn in2002, which was more thancompensated for in 2003. Salesvolumes of radiation curecoatings increased by 6.7% to4800 tonnes in 2003. Frenchproduction of printing inksdecreased by 1.8% to 94,645tonnes.

Conductive polymers developed toreplace chromates
A new group of corrosion-resistant conducting polymers hasbeen developed as a replacementfor toxic chromates in paints andother coating systems by thegroup led by Prof Sze Yang atthe University of Rhode Island.The new product is a conductingpolymer that is used as an additiveand can emulate the mostimportant functions of chromates,ie, it inhibits the process ofcorrosion electrochemically. Unlikeother efforts to develop single-strand, corrosion-resistantconducting polymers, this low-costpolymer has a second strand thatallows a variety of modificationsto its physical structure, making itmore malleable and adaptable formany application processes,including spraying, dipping or spincoating. Major potential marketsinclude coating of aluminiumalloys for aircraft, aluminium andsteel for the automotive industry,and concrete-reinforcing bars forbridges, highways and buildings.The polymers are effective as alow-cost, minor additive to paint,and can be soluble in commercialpaint solvents and used in water-based epoxies. It also is effectivefor surface treatments, steel coilcoating, and as a corrosionresistant primer under other resin-coating systems. Contact: ProfSze Cheng Yang, University ofRhode Island.
