In polyvinyl chloride, Santicizer® 278 shows low flexibilizing efficiency, yet formulations are fast processing. The end product will be highly resistant to staining and dirt pick-up and will retain its properties well even when exposed to high temperatures, extractants -such as solvents, oils, grease -and other severe-use conditions.
Santicizer® 278 has been found to be especially effective in vinyl systems, which require extremely good migration resistance. Typical of this effect is the use of Santicizer® 278 in automotive sealants. Santicizer® 278 provides excellent paintability with "Hi-solids" automotive enamels and resists migration into the paint.
In paints and coatings, Santicizer® 278 helps develop high-performance products. In acrylic coatings, Santicizer® 278 promotes excellent resistance to water spotting, greater toughness and excellent adhesion. When formulated at a level to impart flexibility equal to that obtainable with Santicizer® 160, acrylic powder coatings will show even better flow-out characteristics.
In polyurethane's, Santicizer® 278 shows excellent compatibility and is recommended for urethane fabric coatings and free film. Its excellent permanence allows it to be used without detracting seriously from the high performance that warrants the use of urethane for the application. Santicizer® 278 is excellent plasticizers for use in caulks and sealants, which are based on chlorinated rubber, butyl rubber, polysulfides or polyurethane. Santicizer® 278 is the standard against which other plasticizers are judged in polysulfide sealant applications, offering outstanding functionality and unequaled permanence. In polyurethane sealant applications, Santicizer® 278 offers excellent permanence, low freehydroxyl content and outstanding "body" in the sealant. Its low-moisture content, and low acidity. It doesn't interfere with the chemistry of the curing system. In caulks and sealants for automotive applications, for example, its low volatility, anti-fogging and migration resistance characteristics are unique.
