K-FLEX® PG

K-FLEX® PG is a grade of dibenzoate designed primarily for use in PVC compositions. K-FLEX® PG is a very high solvator for vinyl so it is particularly useful in blends of plasticizers to allow the tailoring of performance characteristics. K-FLEX® PG imparts outstanding stain resistance in vinyl compositions as well as excellent durability properties.

Product Applications

In addition to PVC, K-FLEX® PG can be used in the following areas:

  • Latex adhesives
  • Latex caulks and sealants
  • Latex coatings
  • Sealants

In adhesives, K-FLEX® PG performs well although it is not as efficient as other dibenzoates. This is an attribute that allows for higher plasticizer loading without degrading the desired performance. It is also compatible with coating polymers and is lower in VOC than some traditional phthalate plasticizers. K-FLEX® PG is highly polar - this indicates a large potential for use in most polar polymers.
