K-FLEX 500P

LOW-VOC, DIBENZOATE COALESCENT TAILORED FOR ULTRA-LOW-VOC APPLICATIONS
  • Product Type: Dibenzoate
  • Master Product Number: MITM12157
  • Product SKUs: ITM21358, ITM25968

Product Details

K-FLEX 500P is a dibenzoate coalescent for environmentally friendly, low-VOC paints. Specifically designed for the coatings industry, K-FLEX 500P provides formulators with a solution that meets regulations and consumer demands for lower VOC content, without sacrificing performance and value.

Offering excellent scrub resistance and gloss, K-FLEX 500P aids in the development of desirable performance characteristics while offering improved handling due to low temperature flexibility. Its performance and value make it a viable replacement to higher-volatility coalescents such as TMPDMIB (2,2,4-trimethyl-1,3-pentanediol monoisobutyrate) or even low-VOC types such as triethylene glycol di-2-ethylhexanoate.

K-FLEX 500P is also used as a non-phthalate plasticizer in adhesives, plastisols, and other applications requiring a polar plasticizer with a lower VOC content.

Benefits

  • High scrub resistance and gloss
  • Low freeze point
  • Excellent choice for low-VOC architectural paints and coatings
