March 1991 PIGMENT AND RESIN TECHNOLOGY 3 Market expands for fillers and extenders As readers will know, although there is a long tradition in the coatings industry of using fillers, improvements in the quality of various fillers means the market is expanding. This view is supported in a recent Frost & Sullivan report which explores the market for fillers, opacifiers and extenders throughout Europe. It forecasts a rise in sales from the 1988 figure of $3.8 bn to $4.7 bn by "Many of these materials are relatively inexpensive silicates obtained by subjecting minerals to simple refining processes after extracting them from the ground," the report says. "However, in spite of this apparent simplicity, the applications and markets for them show surprising diversity, dynamism and growth potential." The report looks at natural minerals such as kaolin, calcium carbonate, talc and silica as well as chemical products like titanium dioxide, antimony oxide and BaSO4/ZnS lithopone; the latter three are, of course, really pigments. The paint industry is the largest market in value terms for fillers, opacifiers and extenders, and the second largest in weight. Calcium carbonate and dolomite are the most widely used fillers in the paint industry, wit h demand at 920,000 tones in 1988, and is used mainly for decorative or building paints for emulsions and exterior wall coatings. In spite of recent speculation on possible health risks, the report says the market for antimony oxide, which is used as a fire retardant additive in polymers and copolymers, is strong and adds that fibrous and platey fillers, such as wollastonite, will play an increasingly significant role in both fibre reinforced polymer composites and the so-called "engineering polymers" of the future. Organic pigments Another Frost & Sullivan report (Tel: 071-73 0 3438) deals wit h the European market for organic pigments. It says that increased demand for pigments wil l fuel growth in the 1989 $1.8 bn European organic colourants market during the coming years. The market is split into two distinct product groups — dyestuffs, which dominate with a 60 per cent share of sales, and pigments. Dyestuffs sales are sluggish and expected to reach only around $1.2 bn, by 1994, compared to the 1989 total of $1.1 bn. In contrast, growth prospects for organic pigments are forecast to be fairly buoyant with sales increasing from $750 m to $893 m by 1994. Western Europe accounts for around a third of the world organic pigment demand. One area highlighted by the report which should boost this market is the replacement of cadmium pigments. Organic pigment replacements for cadmium, now banned by many countries, include those based on anthraquinone, benzimi- dazolone, quinacridone, diazo condensation products, isoindoline, perylene and perinone. Frost & Sullivan forecasts particularly good growth prospects for organic pigments based on these, along with those made up of monoazo and diazo. The printing industry is the major user of organic pigments, accounting for 50 percent of the total demand in 1989. Gravure and offset inks represent close to 60 per cent of output wit h flexographic water-based inks accounting for nearly 20 per cent. Frost & Sullivan highlights the potential demand within the packaging industry for water-based inks following recent technologi cal advances in pigments specifically designed for waterborne systems.
