AS THE
Y E A R S ROLL O N There îs a generous amount of thoroughly dependable reliability in every Leyne Well Water System ever built! In the postwar years to come, that outstanding feature will be greatly appreciated by thousands of municipal and industrial executives. Even during the most strenuous days of war emergency, Layne quality was rigidly maintaïnedThere is more to a Layne Well Water System than reliability. In efficiency, ihey are beyond comparison. They lead the world in records of long life. Maintenance cost, year in and year out, is only a minor item. Layne Well Water Systems are today serving the world's greatest cities, manufacturers, war plants, railroads, mines, naval stations, ship yards and training camps. In thousands of cases, both in this land and in foreign countries, they have met and far surpassed •the most rigid requirements in quality, efficiency and low operation cost. If your post war plans call for the use of more water, Layne engineers will gadly cooperate' in providing valuable recommendations.

Î . Is a resinous dispersion chat is completely compatible with Neoprene latex — blends with it intimately. 2 . Produces Neoprene latex adhesives suitable for almost all former natural latex uses and possessing all the added advantages of oil resistance, etc. characteristic of Neoprene. 3 . Provides N e o p r e n e latex a d h e s i v e s w h i c h have pressure-sensitivity Cdry t a c k ) from a few h o u r s up t o 4 o r 5 days, as d e s i r e d . 4 . Contains necessary anti-oxidants and protective agents to insure proper ageing of the compounded adhesives. 3 . Enables extension of Neoprene latex at substantial over-all savings. (Due to the unusually high strength of Neoprene, greater extension is possible in proportion to true rubber-like characteristics aesired.) Can be compounded with Neoprene latex in your own equipment, or UBS will compound and ship the desired finished adhesive to you.
^^^^^^^^^^^â^lSfi Laboratory Tests show UBS formulation PR-154 to be the most satisfactory Neoprene Latex Compound Base. β • As the above graph illustrates, many dispersions w h e n compounded w i t h Neoprene Latex s h o w definitely unsatisfactory ageing qual ities. In fact, only one out of t h e six competitive compound bases tested by the UBS Laboratories stood up to PR-154 in bonding s t r e n g t h and lack of deterioration. T h e result of many years of practical experience compounding Neoprene, PR-154 is an original formulation of t h e UBS Laboratories. Write t o d a y for further information.
