Product: K-FLEX 500

K-FLEX® 500 Product Description

K-FLEX 500 is a blend of dipropylene glycol dibenzoate and diethylene glycol dibenzoate in a ratio of about one to one by weight. K-FLEX 500 was created to take advantage of the excellent performance of diethylene glycol dibenzoate but with the added advantage of the better handling characteristics imparted by dipropylene glycol dibenzoate. Like K-FLEX DP, K-FLEX 500 is a polar plasticizer that is a high solvator for PVC applications. K-FLEX 500 is also compatible with polar polymers such as polyvinyl acetate.

K-F LEX 500 is useful in a wide variety of applications:

·  Latex adhesives, as a general purpose plasticizer

·  Latex caulks and sealants

·  Coatings

·  Plastisols, as an excellent solvator for use in such applications as resilient flooring

This traditional dibenzoate blend remains a standard in the industry.
