WEB EXCLUSIVE: INTERNATIONAL COATINGS EXPO 2003
Heating Up The ICE Floor
PHILADELPHIA, Pennsylvania, USA - Nobody on the show floor of ICE 2003 in the Pennsylvania Convention Center would dare tell the bobbing and weaving line of dancers doing the "LOCOMOTION" that paint people don't know how to have fun.
For the benefit of the uninformed - say, visitors from overseas or members of the younger generation in attendance at the International Coatings Expo (ICE) - the "Locomotion" is a Rock ‘n Roll song and dance number immortalized by the American pop group the "Shangri-Las" more than 30 years ago. Maybe all those free spirits shaking their extremities on the ICE floor were making up for lost time, enjoying the assignment of giving a new twist to this venerable industry institution that was called the "Paint Show" back when the Shangri-Las first made the pop charts.
And the Shangri-Las themselves, showing almost as much hop in the hips as they did in the 1960s, were there in person, leading the charge of these ICE dancers, helping the Federation of Societies for Coatings Technology (FSCT) raise the curtain on a new look for the ICE, 2003 edition. For the first time, the show debut was a late-afternoon opening of the exhibition floor followed by a rocking, rolling "Philadelphia Block Party," complete with food, drink and musical entertainment by those heretofore mentioned Shangri-Las.
Times are a-changing, indeed, for the FSCT and the ICE as the show marked its 68th year in 2003 and headed toward number 69 in Chicago in 2004. The 2004 event, scheduled for Oct. 27-29, will initiate another new tradition, as the ICE will then begin a semi-annual schedule and will be anchored in Chicago. The FSCT says it will plan smaller, regional shows and conferences for the intervening years, although no details have not been announced.
The FSCT said attendance at this year's ICE totaled 6,237, down slightly from approximately 6,400 for the 2002 show in New Orleans, Louisiana. The total number of exhibitors at this year's ICE was 279, a gain of 18 from the 2002 show. Total exhibition space for the 2003 ICE, however, declined slightly from 2002, with a total of 48,800 square feet. The FSCT said this year's show featured 53 new exhibitors.
Perhaps size does matter, but the slightly slimmed-down ICE 2003 hit the right notes in the view of many participants. The dancing in the aisles may have concluded with the opening-night hoopla, but show business was far from slow business, judging from the upbeat reports on traffic quantity and quality heard from exhibitors and visitors.
On the other hand, major themes sounded by many show participants reflected a cautious attitude regarding business prospects. Most observers are taking a wait-and-see stance on economic directions in North America and Europe despite the recent report that the U.S. economy expanded by a robust 7.2% in the third quarter.
Adding to the air of economic uncertainty are anxieties about the impact of rapid industrial and economic expansion in Asia, particularly in China, and apprehension in some political quarters about alleged trade inequities and imbalances.
‘Green' Technologies Continue to GerminateWhile the ICE may not measure up to the shows of yesteryear in terms of blockbuster technology introductions, a number of key suppliers rolled out significant news announcements at ICE 2003.
Not surprisingly, technologies promising environmental and economic benefits were given plenty of play. But beyond the old standbys of minimal VOC or HAP content looms an emerging hotbed of R&D that is focused on "renewable" sources of raw materials for coatings and related products.
The growing interest in things green - literally, as in products derived from plants - is brewing in the laboratories of some very sizable companies, including Cargill Inc., Archer Daniels Midland Co. and The Dow Chemical Co. In Philadelphia, Dow reported on its investigation of a new class of amine-cure epoxy coatings resins based on oleochemicals derived from sunflower, castor and other seed oils.
Dow said the experimental materials are viewed as the basis for the development of a group of new materials made from renewable resources. The company also said it is exploring opportunities in the marketplace and looking for potential development partners.
The company says experimental epoxy resins could potentially produce coatings with a number of advantageous performance characteristics, including low viscosity without solvent; practical cure rates with conventional curing agents; strong adhesion to metal substrates; UV resistance, weatherability and corrosion resistance; resistance to hydrocarbons and solvents; and toughness.
In news of interest to the European market, Reichhold Inc., another key U.S.-based supplier, announced the recent completion of a plant expansion in Vienna that brings production of its glycidyl methacrylate acrylic (GMA) powder-coating resins to Europe. Reichhold, which did not participate in the ICE as an exhibitor, said the expansion provides the company with a highly automated, state-of-the-art production line for the manufacture of GMA acrylic powder-coating resins. The plant's initial annual production capacity will be approximately 4 million pounds, with the potential for expansion as needed to meet demand.. The resins are used primarily for powder coatings for automotive applications.
Reichhold formerly supplied its GMA powder resins exclusively by import from Asia through parent company Dainippon Ink and Chemicals (DIC).
Gary Krall, Reichhold chairman and CEO, said the production capacity gives Reichhold and DIC the ability to meet increased demand for GMA resins expected during the next decade. He said the new capacity makes Reichhold the largest producer of GMA resins in Europe, and also makes Reichhold/DIC the only GMA supplier with two production plants.
GMA acrylic resins are reported to produce high-durability powder coatings and are primarily used in automotive applications such as full-body clear coats, wheel clear coats and pigmented topcoats. The resins also are used as crosslinkers for matte powder coating finishes.
Also making noteworthy announcements at ICE were Air Products and Chemicals Inc., BASF and Lyondell Chemical Co.
The following is a review of some of the product and company news at ICE 2003.
A&D Weighing, Miltipas, California, introduced the SV-10 Sine-Wave Viscometer, which employs a tuning-fork vibration method in the measurement of viscosity in coatings, ink, chemicals, and other materials.

BASF, Mount Olive, New Jersey, introduced the Acronal Optive 330 acrylic latex, billed by the company as the first all-acrylic, low-VOC gloss latex for the North American paint market that matches the performance characteristics of higher-VOC resins. The company said the product provides hardness, block resistance, wet adhesion and gloss at VOC-content levels below 50 grams per liter (g/l). The resin properties are reported to be the result of a multi-phase polymer structure with a unique particle morphology that provides high block resistance and permanent flexibility. The company said the very fine, anionic dispersion delivers weathering resistance, water and blush resistance, alkali resistance, and freeze-thaw stability. Application properties are reported to include excellent flow and leveling and brushing and film build. In addition, an adhesion promoter provides adhesion to wood and problematic substrates such as aged alkyd paints, the company says. Recommended applications include gloss paints for interior and exterior substrates, with use in satin and semigloss paints also possible.
BASF also announced plans to modify an existing manufacturing facility at its Wyandotte, Michigan, site to produce amino resins for the North American coatings market, with construction of the facility scheduled to begin by the end of this year and resin production expected to start in the second quarter of 2004. The facility's design will allow for rapid expansion to meet increased demand, the company said. Amino resins add hardness, gloss and resistance properties to a variety of industrial coatings.

RPA Process Technologies, Portage, Michigan, introduced the MCF, or Magnetically Coupled Self-Cleaning Filter, based on a design that moves the filter-cleaning disc without shaft or drive external seals. The company says filtrate flows from the top down and from the inside of the media toward the outside to increase contaminant retention. A spring-loaded cleaning disc travels top to bottom inside the filter media, and the cleaning disc and flow continually drive undesirable solids downward where they are concentrated in the purging chamber for expulsion. A hollow shaft at the center of the system contains a piston with rare-earth magnets, which are coupled to external magnets housed in a carrier connected to the cleaning disc. Pneumatic actuation moves the inner magnet up and down the shaft, with the cleaning disc following.
Sartomer Co., Exton, Pennsylvania, introduced Krasol HLBH-P 3000, a saturated aliphatic liquid polyol for use in polyurethane coatings. The hydroxyl-terminated polyolefin resin offers performance properties that include low-temperature flexibility; impact resistance; hydrolytic resistance; miscibility with mineral fillers and plasticizers; and low surface tension, the company says.
