PRESERVATIVES
• Penta-protected wood lasts up to 4 times as long as untreated lumber. This kind of protection is a profit able investment for people with maintenance problems . . . whether they're running a park department or a light and power company. Water-repellent solutions made with RCI PENTA protect lumber against decay and termite attack . . . keep wood dimensionally stable . . . reduce its tendency to crack or check. Wood protected by RCI PENTA solu tions is clean, easy to handle. Today, penta treatment is the fastest growing method of preserving wood. And RCI, one of America's fastest growing chemical companies, is a top source for pentachlorophenol. If you're currently engaged in, or are considering, the manufacture of wood preservative solutions, fungicides, bactericides, algicides, or herbi cides . . . or if you do your own treating of lumber, call Reichhold for pentachlorophenol . . . now being pro duced by RCFs Pacific Northwest Division in Seattle.
