Isophthalic polyester resins no doubt are of higher grade and offer high strength, better flexibility and chemical resistance. It is now becoming preferred material in industries.
It is an organic compound with the formula C6H4 (CO2H)2. It is a colorless solid and is an isomer of phthalic acid and terephthalic acid. It is thixotropic polyester resin. Particularly this is water-resistant and is used in construction of all equipments designed for permanent immersion.
It is better suited for corrosion environments, elevated service temperatures, and has greater mechanical properties. It was chosen in this case because of its corrosion resistance to seawater and its impact resistance

- Also it can be used where superior water resistance is desirable.
- Used in mold making because of its extreme durability.
- Isophthalic Resins are suitable for use where higher levels of chemical and heat resistance are required.
- Isophthalic polyester resins are a broad class of resins formulated from isophthalic acid, glycols, and maleic anhydride
- It exhibit good resistance to water, acids, weak bases, and hydrocarbons such as gasoline and oil.
