Frequently Asked Questions About Isophthalic Resin

Technical and commercial guidance for purchasing and applying isophthalic polyester resins

What is isophthalic resin (ISO resin) and its key advantages?

Isophthalic resin (ISO resin) is an unsaturated polyester resin synthesized with isophthalic acid. It offers superior corrosion resistance, high tensile strength, excellent water barrier (osmosis resistance), and UV weatherability compared to standard orthophthalic resins.

What is the difference between isophthalic resin and vinyl ester resin?

Isophthalic resin delivers higher durability and chemical resistance than standard polyester resins at a cost-effective price point. Vinyl ester resin offers extreme acid/alkali resistance for harsh chemical tanks. ISO resin is the optimal balance for marine hulls, engineered stone, and anti-corrosion linings.

Do you export isophthalic resin to the UAE, UK, and North American markets?

Yes. Lechi Composites exports bulk isophthalic resin globally to Dubai/UAE, the United Kingdom, the United States, Southeast Asia, and Europe. Standard packaging includes 220kg steel drums and 1000kg IBC tanks with full TDS/MSDS and export compliance documentation.

Can isophthalic polyester resin be customized for specific gel times and viscosities?

Yes. As a direct chemical manufacturer, we provide custom formulation services adjusting viscosity (150-1900 mPa·s), thixotropy, and gel times (4-18 minutes) for hand lay-up, spray-up, pultrusion, and casting.
