PARTICLES INTO PROFITS: T O GLORIFY A GRANULAR MATERIAL, T R Y PHENOLIC RESIN
FROM S A N D , A N E W METHOD of making molds for casting metal becomes possible with Durez phenolic resins. Thin, tough, resin-bonded molds and cores turn out clean, accurate castings that reduce machining cost. WITH CORK, A TOUGHER TILE is locked together by Durez resin. Process heat makes the resin set hard to give built-in durability. Not even boiling water can weaken the bond. It resists heat, moisture, abrasion—for keeps. FOR SILICA, A BRIGHT FUTURE beckons in mortars and trowel-on floor finishes that harden without heat, stand firm against strong acids and alkalies. In these corrosion-resistant compounds, a Durez resin is the binder. What particles do you want to bond? Give yourself a head start by coming to Durez for technical assistance. We've investigated more than 20,000 phenolic resin formulas for industrial bonding, compounding, and impregnating. We're constantly developing new ones. For facts on them, write for bulletin, "Durez Industrial Resins."
