K-FLEX® DP

K-FLEX® DP is useful in a wide variety of applications including:

• Latex adhesives
• Latex caulks and sealants
• Sealants
• Coatings
• Plastisols
• Melt compounded flexible vinyl compositions

K-FLEX® DP is an excellent choice for applications requiring a high solvating plasticizer. In addition, K-FLEX® DP can be used as a plasticizer in U.S. food packaging adhesives in accordance with the applicable regulations. Unlike other common dibenzoate products, K-FLEX® DP does not crystallize, making it a sound choice for facilities without heated storage.

• This product is stable and is not considered corrosive for metals and glass. The organic products of combustion are carbon oxides and water.
• This product should be stored away from excessive heat, sources of ignition and reactive materials. Limit indoor storage to areas equipped with an appropriate sprinkler system.
• Typical storage systems keep this product at approximately 86-100°F (30-38°C) and atmospheric pressure. If the moisture content of the ester is critical, the tank should be padded with nitrogen or vented to the atmosphere through a desiccant dryer. An over pressure/vacuum relief device should be provided for the tank.
• K-FLEX DP does not have a simple freeze point, instead forming a glass at very low temperatures. It can become very viscous at low temperatures, so it is therefore recommended that storage tanks be heated and insulated and that pumps and transfer piping also be heat-traced and insulated.

Bulk Tank: K-FLEX® plasticizers may be stored in type 304 stainless steel insulated and heated tanks. Storage tanks should be nitrogen padded to reduce discoloration of the product. Heat traced, type 304 stainless steel pipe and valves should also be used.

275 Gallon (Intermediate Bulk Container) Tote: The tote should be kept in a warm location >70°F (21°C) to prevent material from becoming too viscous and difficult to remove from the tote bin. If the material becomes too viscous or partially frozen, totes may be heated using heating blankets/jackets or a hot box to melt the material. Special attention must be taken to insure that the tote is completely sealed against moisture and oxygen/air during heating.
