Report on precipitated cdtcium carbonate
Company Inc.)
The major change in the world XC industry has been the introduction and expansion of satellite PCC plants at papermills, particularly in North America, according to a new report froryl market analysts Roskill entitled “‘DIE ECONOMICS OF PRECIPITATED CALCIUM CABBONATE 1991.” In a detailed section on end-use markets the report looks outside the paper industry at other markets for PCC such as plastics, paint, rubber and adhesives and sealants. Some growth in demand for PCC in these applications is forecast but the tonnages involved are less signXcant when compared with the paper industry.

Dmmnd for additives in surface stints industry
According to a study by Information Research Ltd. of London, there are about 15 major classes of ad~~ves in widesp~ad use throughout th.eEuropean paint rn~~act~g industry. However as most additives are used in relatively small q~tities, many below l%, the net effect on the overall costs of a formulation are usually small. The extentto which additives are used in each ~0~~ relates directly to the extent of p~duction of coatings in each country and the spectrum of paint types. So the most important users of paint additives in Western Europe are Germany (17.63/o),Italy (7.1%), France (69%) and the UK (6.1%). The Nordic and Benelux countries taken together are also sizable users, acco~t~g for 4.3% and 4.4% of demand respectively, as in Spain with 3.4% of the total usage for all Europe, In Eastern Europe, the situation is dorn~a~d by the USSR which accounts for some 33.3% of the total pan-European demand for additives. The other important markets are Poland (3&O,), Romania (1.8%) and Yugoslavia (1.7%)). The customers for the manufacturers and suppliers of additives are of course the 2.000 or more pa~~~~g concerns in Europe.

of production is in the hands of a few large multinational groups which have substantial in-house technical facilities. h&my of these fms prefer to modify their raw materials rather than to use additives to overcome any defects in their coating systems, with the result that often the widest users of paint additives are the medium and smaller sized paint rn~~a~t~g companies.
The majority
The most impotiant generic class of additives are the driers whose total European usage is almost 55,000 tons, followed by wetting agents (over 20,000 tons) and levelling agents (18,525 tons). Various types of special effect inducers such as gloss controllers account for 16,750 tons. Of lesser importance, in decreasing order are sickener, suspension agents, etch agents, antifouling agents, antifoaming agents and anti flooding/ floating agents all of which are utilised to the extent of 2,000 tons a year throughout Europe. It is expected that the demand for paint additives will show a steady if unspectacular growth over the next decade. It is postulated that the total annual gage of all types ~o~hout Europe will increase to around 188,750 tons by 1995 and to over 208,000 tons by the year 2000. However it is not envisaged that there will be any dramatic changes in the types of materials that are used.

PRODUCT Antimony pentoxide in epoxy resins in the UK
INFORMATION
Croxton & Garry in the UK has published a technical bulletin which examines the benefits of using its Nyacol antimony pentoxide in epoxy resins. The document is primarily aimed at companies involved in the manufa&ure of epoxy laminates for FCBs, pa~i~~~ly those looking to achieve FR-4 or FR-5 NEMA standards. The company believes it will also be of interest to epoxy formulators and those with an interest in the subject of flame retardancy in epoxies. The company claims that the Nyacol .products can be used as flame retardant synergists with the brominated epoxy resins commonly employed in the production of WB laminates. This is said to result in formulations with lower bromine levels, giving cost savings and improved thermal and electrical properties. ID addition, the Nyacol antimony per&oxide is believed to have little effect on laminate translucency and will not poison the electroless plating baths used to copper clad PCB la.rninateson both sides. This ‘poisoning’ effect has been observed with antimony trioxide and has prevented its use in this application.
