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
