can confidently schedule two-, four-, and even six-year drydockings without bottom paint repairs being necessary except for major colli- sion or catastrophic grounding damage. Of course, no matter where a vessel works there is sig- nificant savings in knowing that no blasting or painting needs to be done on the bottom until its sixth or eighth year of service. Glidden's vinyl antifoulant al- lows little or no tightly adhering growth, even in badly polluted waters, and the system is resistant to delamination and to abrasion from repeated groundings on shal- low bottoms. When repairs are re- quired, turnabout is very quick. Under normal conditions, total drying time for a four-coat system is eight hours. The vessel may then be launched immediately or left dry indefinitely with no reduc- tion of antifouling protection. HEMPEL'S Circle 40 on Reader Service Card Hempel's Marine Paints A/S, with headquarters in Denmark and 26 factories worldwide, re- cently announced a new approach to non-polishing antifoulings—a product area many sources esti- mate accounts for some 85 percent of the total world market for anti- fouling coatings. In half a century of research and development of traditional, non- polishing antifoulings, Hempel's has gained a thorough under- standing of their effects. It is this know-how that now enables the company to introduce, under the name Classic, an optimized range of these traditional coatings. The Classic line consists of four products: antifoulings 7611, 7633, 7655, and 7677, which together cover the full non-polishing spec- trum by taking into account the degree of protection required by individual vessels for their partic- ular trading pattern, activity level, and desired drydocking interval. The versitility of the Classic range, through combining the products' variable film thickness and coating sequence abilities, provides no less than 13 alternate specifications. This, together with the easy-to-follow selection table, not only allows the shipowner the widest choice, but enables him to recognize and choose the optimum non-polishing system for each vessel. HENKEL Circle 41 on Reader Service Card Henkel Corporation of Minne- apolis provides Versamid® 280B75 polyamide resin and Genamid® 2000 amidoamine resin, the cur- ing agents used by formulators to produce unique epoxy coating that meets the U.S. Navy's P-24441 (SHIPS) Specification and offers good adhesion to poorly prepared surfaces, low-temperature cure, and corrosion resistance without rust- inhibitive pigments. Laboratory tests conducted by Henkel reveal that coatings based on these resins "creep" into small cracks to displace water and for- eign materials. There is also chemical absorption on metal sur- faces to prevent corrosion, and no zinc pigments to inhibit welding. INTERNATIONAL Circle 42 on Reader Service Card Replacing International Paint's Intersmooth SPC range, HISOL is the latest development of this tried and true SPC, being exactly the same as Intersmooth when dry, the only difference being in the product application. A prime fea- ture in the engineering of this new coating is its greatly increased volume solids and its ability to be applied in a range of dry film thicknesses. For a typical paint scheme, fewer coats are now re- quired. Higher solids mean more square feet per gallon, less solvent in the air, and up to 30 percent savings in application and less (continued on page 40) LTJh l/y i 1 • X iX* | | 1 II IT^ 1 1 HlllI^"! MAGNUS MARITEC With Magnakote, Magnus Maritecs Cost-Effective Tank Coating Formula, Magnakote is the most economical soft chemical coating compound on the mar- ket: less than 3C per sq. ft.! No other soft coating gets near it for cost-effective tank & void space corrosion protection. Magnakote is formulated for efficiency- no special surface preparation required prior to application (spray or float method). A pioneering product of advanced, soft chemical coating technology, Magnakote is extremely durable. Thus, maintenance and repair costs are reduced significantly. Spot repairs are easy. And, Magnakote re- moves quickly for overhauling. It's non- toxic, with a high flashpoint (320°F/160°C). Magnakote—efficient, cost-cutting corro- sion protection.
