PIA, Purified Isophthalic Acid

The white, free-flowing crystalline powder is available in bulk and a variety of packaging sizes.

In coatings PIA

  • Produces high molecular weight polymers for hardness, flexibility, weatherability, and fast cure in waterborne, powder, and coil coatings
  • Enhances hydrolytic stability to improve the shelf life of waterborne coatings
  • Decreases dry times for high solids and traditional solvent-borne coatings

In polyester packaging PIA

  • Provides clear bottles in a range of shapes and sizes and thicker preforms for returnable/refillable containers
  • Broadens processing window that reduces cycle time and lowers energy requirements
  • Improves taste in bottled water without the unpleasant flavor of acetaldehyde
  • Reduces permeability to carbon dioxide and oxygen, keeping beverages carbonated and flavorful longer

In unsaturated polyester resins PIA

  • Provides outstanding resistance to various acids, solvents, and other chemicals
  • Offers an excellent combination of moderate cost and high performance often matching that of higher cost, corrosion resistant polymers including vinyl esters and bisphenol A polyesters for many applications
  • Has demonstrated exceptional performance in products as diverse as in-situ pipe remediation, gasoline storage tanks, chemical storage tanks, ladder rails and industrial gratings, protective coatings for watercraft, structural automotive parts and boat hulls, and functional and decorative solid surfaces
  • Presents ease of synthesis and fabrication in pultrusion, sheet molding compound (SMC), bulk molding compound (BMC), hand lay-up and spray-up, castings, injection molding, resin transfer molding (RTM), reaction injection molding (RIM), centrifugal casting, and filament winding

In diverse applications PIA

  • Provides a chemical platform for making thermal and oxidative stable aramid fibers, polyester elastomers, oil additives, adhesives, X-ray contrast agents, and fiber dye enhancers
