... solid plasticizers show more versatility than just about any other group. You find them in
adhesives, lacquers,`foams, rigid compositions and films... and in each type they perform
_ unusual functions. Many times it is the solid plasticizer that allows a different product to be
. made, one that commands attention by its uniqueness.
.
This folder will acquaint you with the solid plasticizers available from Monsanto, and Monsanto can offer you the industry's largest selection. You'll find detailed information on each plasti cizer in a Monsanto technical bulletin ... see page 7 for the list. If you'd prefer, a Monsanto salesman will call and discuss your particular application. Investigate the new products or ' product improvements you can make by using solid plasticizers. Monsanto technical service will be glad to show you how solid plasticizers can work for you.
SOLID PLASTICfZERS GIVE YOU...
Hot processing
Hot processing is one area where solid plasticizers perform to good advantage. For instance, if you're mixing plasticizer and resin in a Banbury mixer, a solid plasticizer will melt at the processing temperature and function as a solvating liquid plasticizer for the resin. The low ered viscosity improves the formulation flow and results in much easier processing. Upon cool ing, the plasticizer returns to its solid state which produces a stiff film or article.
Solvent use
:.
In lacquers, certain solid plasticizers permit higher solid percentages. High-solid lacquers need fewer coats to build up a surface and therefore reduce application costs. As the lacquer dries, the presence of the solid plasticizer helps reduce blushing, sweating and separation.

Delayed-tack and heat-seal adhesives owe their existence to solid plasticizers, because it is the solid plasticizer that makes delayed-tack and heat sealing possible. Delayed-tack adhesives are activail'd by heat, and once activated, remain* tacky long enough to permit handling before the
adhesive cools and sets. The sharp melting point of solid plasticizers provides a sharp activa tion point for the adhesive. This activation temperature varies with different solid plasticizers, and special adhesives can be easily formulated to fit handling methods by selecting the . proper solid plasticizer. Delayed-tack adhesives are covered by U. S. Pat. Nos. 2,462,029; 2,608,542; 2,60S,543; 2,613,156 and 2,613,191.
For films...no blocking
' Solid plasticizers can be used with other primary plasticizers to produce tough, clear films that feel dry and separate .easily. Liquid plasticizers used alone often cause blocking due to a slight surface tackiness. Solid plasticizers also add resilience to films and impart exceptional resist
. ance to extraction by kerosene, oils and greases.
For rigid products...easier processing
` Processing of rigid vinyl products can be made easier by using solid plasticizers ... without - changing present equipment or methods. With heating, the solid melts and acts as a solvating liquid plasticizer for the resin. Upon cooling, the article becomes rigid because the plasticiz ing effect of the solid plasticizer is slight at room temperature. Used strictly as a processing aid, the solid plasticizer pays its own way by lowering processing costs.
For heat'Seal coatings...sharp activation temperature
Like adhesives, heat-seal coatings require the sharp melting points of solid plasticizers to - give them the heat-seal property. By themselves, liquid plasticizers cannot endow coatings with
a sharp activation temperature. Instead, the coatings lend to block and be tacky at tempera tures beneath the activation temperature. In this type of coating, solid plasticizers can be chosen to provide an exact temperature at which the heat-seal property is activated. And be . " ` neath that critical temperature, the coating does not block or have tackiness.
For rigid foams...toughness
-
!
t
|
! j.
In the chemically-blown foams, solid plasticizers can be used to add toughness to the finished foam.
m
In the plastisol foam process, solid plasticizers thicken the starting formulation to make pos
sible more uniform cell formation as the gas is released. A uniform cellular structure makes
the foam tough and provides uniform dimensional stability.
i In chemically-blown vinyl foams made by milling or Banburying, the solid plasticizer acts as a I liquid solvating plasticizer at the process temperature to make possible easy processing. At room j temperature, the solid plasticizer's inefficiency results in a higher compression-resistant foam.
i- . For lmpregnants...Aetfer flow
To get even disixTxement of impregnating powders, solid plasticizers can be used as a flow * aid for producing brake band linings. The flow aid proi>erty is also useful in certain types of
adhesives, phenolic moldings and thermosetting ureas.
