HETRON Resin selection guide for corrosion resistant FRP applications
Hetron™ and Derakane™ epoxy vinyl ester resins by Ashland are designed for corrosion-resistant applications in Fiber-Reinforced Plastic (FRP). This guide provides chemical resistance data for designing corrosion-resistant FRP applications, including updated information and CAS numbers. Some products have been removed; inquiries should be directed to Ashland Technical Service.
Ashland's laboratory in Dublin, Ohio, evaluates Hetron and Derakane resin laminates for corrosive service. Standard test laminate kits are available for exposure testing. Users should provide detailed chemical exposure data when requesting resin recommendations.
The guide categorizes resins into several series based on characteristics and applications:
- High Performance Epoxy Vinyl Ester: Hetron 980/35 and Hetron FR998/35 for maximum heat and corrosion resistance.
- Epoxy Vinyl Ester: Hetron 922 and Hetron FR992 for resistance to acids and bases.
- Chlorendic Polyester: Hetron 197 Series for corrosion and heat resistance.
- Furfuryl Alcohol Resin: Hetron 800 for resistance to organic solvents and aqueous systems.
FRP is favored for its corrosion resistance, heat resistance, electrical and thermal insulation, and high strength-to-weight ratio. It requires low maintenance and is easy to repair.
Recommendations are based on field service performance, laboratory tests, and expert knowledge. Users should refer to industry standards and design guidelines for FRP equipment design.
Hetron resins are liquid polyester and epoxy vinyl ester resins used to create fiber-reinforced structures. Developed since 1954, they are defined by ASTM and ASME standards.
Recommendations are based on field performance, laboratory tests, and expert knowledge. The guide is updated periodically to reflect new data, assuming ASTM C581 standard laminate construction unless noted otherwise.
The FDA lists acceptable raw materials for resins. Hetron 922 and other selected resins comply with FDA regulations.
The guide provides information on the resistance of Hetron resin-based FRP equipment under various conditions. Special considerations are needed for fumes, splash, and tank lining applications.
These resins offer enhanced mechanical properties and are suitable for high-temperature applications, resisting acids, alkalis, and solvents.
Manufactured for maximum corrosion and temperature resistance, formulated for optimal cure with specific catalysts.
Suited for high-temperature and oxidizing environments, such as chimney liners and chlorine headers.
Known for excellent resistance to strong alkalis and acids, not suitable for oxidizing chemicals.
Typical values for mechanical properties are provided, varying from sample to sample. Barcol hardness indicates surface cure.
Tables provide detailed mechanical properties of Hetron resins in both US and SI units, including tensile strength, modulus, and flexural strength at various temperatures.
The document is a technical guide for Hetron™ resins, focusing on mechanical, thermal, and electrical properties, as well as flame retardance. It provides specifications and recommendations for industrial applications.
Tables detail tensile and flexural strength and modulus of Hetron resins at different temperatures, emphasizing reinforcement type and orientation.
Thermal conductivity and expansion are discussed, advising on post-curing conditions to enhance service life, especially for high operating temperatures.
Hetron resins exhibit high dielectric constants and low dissipation factors, suitable for electrical insulation applications.
Many Hetron resins are inherently flame retardant due to their halogenated chemical structure, with industry standards for flame spread ratings provided.
The guide recommends specific post-curing conditions and highlights the importance of reaching minimum Barcol hardness values before startup.
Provides a concentration chart converting parts per million (ppm) to percentage (%).
Includes a Baumé concentration chart for various acids and ammonia at 25°C.

ADVANTAGES Fiberglass reinforced plastic (FRP) has been used for various types of equipment in the chemical processing industry since the early 1950s. Its use has continued to grow in pulp and paper, power, waste treatment, semi-conductor, mineral processing, petrochemical, pharmaceutical, and other industries. Process vessels of all shapes and sizes, scrubbers, hoods, ducts, fans, stack liners, pipes, pumps, pump bases, misteliminator blades, grating, and tank lining systems are just a few examples of products made of FRP. The chief reason for the popularity of these materials is their excellent...

INTRODUCTION Liquid polyester and epoxy vinyl ester resins, as purchased from the resin supplier, are actually polymers dissolved in styrene monomer. The fabricator cures these resins to a solid state, reacting the polymer together with the styrene in the presence of glass reinforcements to produce a fiber reinforced rigid structure. The standards for these structures are defined by organizations such as ASTM and ASME. The development and manufacture of Hetron, epoxy vinyl ester resins has been a continuing process since 1954. They have been used to fabricate thousands of different types of corrosion...

POSTCURING THE LAMINATE For a service temperature below 100ºC (212ºF): A postcure may extend the service life if the operating temperature is within 20ºC (40ºF) of the present CR guide maximum temperature for the service. This means that a postcure can be beneficial for solvent applications with a temperature limit of 25º-40ºC (80º-100ºF). For service temperature above 100ºC (212ºF): Postcure in service may be sufficient, provided the resin specific minimum Bardol hardness values are reached before start up. For service in pure and neutral salt solutions: Postcure may, in general, not be required,...
