MONTAR COMPOUNDS GENERAL INFORMATION Montar* compounds are a scries of high-melting, dark colored polyphenyls. Each has a characteristic range of properties. Montar 3, 4, S and 6 are chlorinated polyphcnyls; Montar 9 is a mixture of straight polyphenyls. All of these compounds are effective as low-cost binders or tackifiers, for adhesives, mastics, or hot-melt systems in which dark color is not objectionable. They are readily incorporated in rubber base adhesives for paper by first dissolving the Montar in a suitable solvent. (See Solubility Data, page 3.) The chlorinated polyphenyls (Montar 3, 4, 5 and 6) contribute flame resistance to specialty asphalt products, concentrations of 30^ or more yield products with in stantaneous flame-out. All Montar products are compatible with polyvinyl chloride up to about 10 parts per 100 parts of resin, and can be used as extender-type plasticizers to reduce formulat ing costs. Their composition suggests that they may be useful as plasticizers for a variety of other synthetic resins. Montar compounds are readily available in large quantities. Sample quantities may be obtained. This bulletin presents sample formulations and information helpful in the development of new formulations. s I >? i o U4 TSa InPannailan anmalnad In Ml MUll* l, < kMI knawladya. and arewata. tori VI a, ara a-Hhawl fiMMMM, tin a m a, 6apan* aw am,al.

As illus trated in the table (below), Montar No. 4 (polychlorinated polyphenyl) contributes flame retardance at con centrations as low as 10%, with instantaneous flame-out above 30%. This property is caused by the formation of an intumesccnt layer on the surface of the mixture, which "snuffs" our the Name. Competition Pure Asphalt 10% Montar No. 4 20% Montar No. 4 30% Montar No. 4 50% Montar No. 4 60% Montnr No. 4 Flame-out Tima 210 seconds 90 seconds 10*20 seconds Instantaneous Instantaneous Instantaneous Holh softening point and brittleness of the asphalt blend are increased as the concentration of Montar is increased. Mending is accomplished by thorough mixing, using heat where necessary. Use in Rubber Adhesives A 50% solution of either Montar No. 4 or No. 5 mixed with a 60%*solids rubber emulsion (1:1 ratio) yields a paper adhesive with good tack. Emulsified Montar The emulsifiability of all the Montar products suggests additional applications in the adhesives field. In a recent test, 5% of an emulsifier was added to a 50% solution of Montar, then the mixture was progressively diluted with water. The emulsion did not break until water dilution reached 160%. Usa In Vinyls Up to 10 parts of any Montar can be blended with 100 parts of polyvinyl chloride resin by simple mixing. TYPICAL PROPERTIES OF MONTAR COMPOUNDS Property Softening Point- (ASTM), C.
