Documented Uses
- Used as a fire-retardant monomer in unsaturated polyester resins, wool fabrics, coatings, epoxy resins, and polyurethane foams; Also used as an extreme pressure lubricant, chemical intermediate, and for special applications in electronic systems, paneling, engineering plastics, paints, and anti-corrosion tanks, pipes, and other equipment; [HSDB]
- Painting (Pigments, Binders, and Biocides) [Category: Paint]
- Plastic Composites Manufacturing [Category: Industry]
- Textiles (Printing, Dyeing, or Finishing) [Category: Industry]
- FIRE-RETARDANT MONOMER IN UNSATURATED POLYESTER RESINS; FIRE RETARDANT MONOMER IN COATINGS, IN EPOXY RESINS, IN POLYURETHANE FOAMS; EXTREME PRESSURE LUBRICANT; CHEM INT FOR DIBUTYL & DIMETHYLCHLORENDATE (PLASTICIZERS)
- In Europe, 80% of the chlorendic acid produced is used in composites for flame retardant building and transport materials. The remainder issued in composites for the manufacture of anti-corrosion equipment, such as tanks, piping and scrubbers. In the USA, Latin American and Far East, the usage pattern is reversed; 70-80% is used for anti-corrosion equipment and 20-30% for flame retardant applications.
