You can count on Du Pont Crystal and Shotted Urea for highest purity A product of continued research a n d d e v e l o p m e n t —Du Pont U r e a is conveniently supplied t h r o u g h a n a t i o n w i d e n e t w o r k of chemical a g e n t s . D u P o n t Urea provides highest quality a n d consistent uni­ formity wherever it's used. Many processors prefer t h e timeproven, pure, crystal form; others find t h e newer, free-flowing "shotted" form meets their high standards and also makes possible reduced handling costs. Both forms of D u P o n t Urea are equally dependable in performance—both are readily available from your local D u Pont Agent. Du Pont Urea effectively serves in a wide number of chemi­ cal applications. For example . . . its reactivity with aldehydes makes D u P o n t Urea extremely valuable in t h e manufacture of urea-formaldehyde thermosetting resins for adhesives, pro­ tective finishes and molding compositions. I t is also used extensively in t h e treatment of paper a n d textiles. If your production or development work requires high qual­ ity a n d performance of urea, why not take advantage of over 20 years of research experience responsible for t h e exacting manufacture of D u P o n t Urea? Your local D u Pont Agent can provide immediate shipment of both crystal and shotted urea in 100-lb. multi-ply paper bags. And remember, too, a D u Pont Technical Representative is always available for as­ sistance when you deal with any of t h e agents listed below.
