Phthalic anhydride is a white crystalline solid that finds use in the synthesis of phthalate plasticizers and alkyd resins. It is a versatile intermediate in the manufacture of numerous industrial chemicals as well as polymers.
Alkyd Intermediate
Paint, Ink & Coatings
Serves as an important raw material for the preparation of alkyd resins, which are widely used as binders in paints, coatings, and varnishes.
Improves the following properties of the alkyd-based coatings: toughness, luster, and adhesion.
Employed in the production of phthalate plasticizers that are incorporated in PVC and other polymers to enhance their flexibility and durability.
It also guarantees the versatility and stability of plastic materials in uses like flooring, wire coating, and car parts.
Used in the manufacturing of unsaturated polyester resins for fiberglass-reinforced plastics (FRP) and composites.
Improves the mechanical properties, chemical resistance, and thermal stability of polyester-based products.
Used as a starting material in the manufacturing of dyes and pigments for coloring of textiles, plastics and coatings.
Aids in the coloration and light fastness of dyed and painted surfaces.
Phthalic anhydride is usually shipped and stored in sealed metal drums or high-density polyethylene (HDPE) containers.
