What is isophthalic resin?
Isophthalic Resin is a medium viscocity, Unsaturated Polyester Resin based on Isophthalic acid. It is specially designed for corrosion resistant applications. It exhibites excellent mechanical properties along with good chemical resistance compared with other isopthalates and orthophthalates.
What is phthalic acid used for?
Phthalates (esters of phthalic acid) are a group of chemicals with a wide variety of industrial applications. Regarding cosmetics, they are used as plasticizers in products such as nail polishes and hair sprays, and as solvents and perfume fixatives in many other products.
What is purified isophthalic acid used for?
The main industrial uses of purified isophthalic acid (PIA) are for the production of polyethylene terephthalate (PET) resin and for the production of unsaturated polyester resin (UPR) and other types of coating resins.
How is isophthalic acid made?
Isophthalic acid is an aromatic dicarboxylic acid industrially produced by the oxidation of m-xylene. Commercially, it is used primarily as a component of PET (polyethylene terephthalate) copolymer, which is used in bottle resins and, to a much lesser extent, for fibers.
What is the difference between ISO and Ortho resin?
ISO resin is one step higher than the ortho resin and is more suitable for corrosive environments, high service temperatures and greater mechanical properties. Iso resins have 42% to 50% styrene because higher molecular weights require more solvent to produce a viable viscosity.
Which is better epoxy or polyester resin?
Epoxy resin has very good adhesive properties, has good chemical resistance and offers some comfort while you use it (less fumes). However, polyester resin, often more than 3 times cheaper, fits most day to day general DIY jobs and using epoxy may be overkill.
What is the meaning of phthalic acid?
Definition of phthalic acid : any of three isomeric acids C8H6O4 obtained by oxidation of various benzene derivatives.
Is phthalic acid unsaturated?
Phthalic Acid Unsaturated Polyester Resin.
What is isophthalic polyester?
Our High-Strength Isophthalic is a thixotropic, low-viscosity polyester resin with excellent heat and chemical resistance. It is corrosion, temperature, solvent, and fuel resistant.
What is formula of isophthalic acid?
C8H6O4Isophthalic acid / Formula
What is the structure of isophthalic acid?
What is ISO polyester?
ISO Resin is a medium viscosity, medium reactive polyester resin based on Isophthalic acid and superior glycols. It exhibits good mechanical and electrical properties together with good chemical resistance compared to general-purpose resins.
What is the difference between Orthophthalic acid and isophthalate?
Orthophthalic acid (1) and isophthalic acid (2). The orthophthalic is the most common isomer for the preparation of alkyds; isophthalic acid can be used to increase mechanical strength and chemical resistance.
What is the difference between ortho and isophthalic resins?
Orthophthalic (Ortho) resins are based upon orthophthalic acid and are a good basic, general-purpose, inexpensive resin. They have styrene content between 35% and 45%, and are used in applications that do not require elevated service temperatures, high corrosion resistance, or high mechanical properties. Isophthalic…
What is the most common isomer of phthalic acid?
The orthophthalic is the most common isomer for the preparation of alkyds; isophthalic acid can be used to increase mechanical strength and chemical resistance. There are three different ‘isomers’ of the phthalic acid depending on the relative position of the two carboxylic groups in the aromatic ring.
What is Orthophthalic isomer used for?
The orthophthalic is the most common isomer for the preparation of alkyds; isophthalic acid can be used to increase mechanical strength and chemical resistance.
