It;s A Model Age . . . based upon the m o l e c u l a r structures t h a t a t o m s build. Structures that bring us a m u l t i t u d e o f vital p r o d u c t s — m a n y of -which, like rubber a n d t h e whole range o f plastics, "benefit b y i m p o r t a n t functions performed b y modern m a t e r i a l s such as M e t a s a p Stearates.
FLUID, SEMI-FLUID, STIFF, STRINGY, ADHESIVE GREASES — l o n g and short feathered—that d o n o t freeze in winter, separate, dissolve or evaporate i n summer, are obtained through use of M e t a s a p A l u m i n u m Stearate. Possessing high temperatureresistance, stability, and water-repellent q u a l i t i e s , these moisture-free lubricants keep m o v i n g p a r t s operating efficiently and economically u n d e r t h e toughest conditions.
UNCUREO RUBBER STOCK, for example, will n o t stick w h e n d u s t e d with M e t a s a p Zinc Stearate, a n d this zinc compound can be used to a d v a n t a g e t o lubricate m o l d s .
AND THERE ARE SCORES OF OTHER VALUABLE SERVICES performed b y M e t a s a p Stearates—from m a k i n g ceramics lustrous and giving face p o w d e r s " s t a y o n " ability, t o preserving fish nets a n d waterproofing concrete. All help t o step up o u t p u t , improve products, promote economies.
IN THE CASE OF PLASTICS, M e t a s a p Zinc a n d Calcium Stearates not o n l y i m p r o v e internal lubrication of molding powders, b u t act as plasticizers. W h e n dusted o n m o l d s , they supply external lubrication and prevent sticking. M e t a s a p Stearates also permit molding a t l o w e r pressures, h e l p speed the m o l d i n g cycle, p r o m o t e longer m o l d life— improve t h e finish o f the plastic product.
