EPON™ Resin 2024

 

 

Product Description

EPON™ Resin 2024 is a solid bisphenol A/epichlorohydrin epoxy resin that contains half a percent weight of the flow control agent, MODAFLOW1. This resin is designed specifically for formulators of thin-film functional/decorative powder coatings who desire to have the flow control agent evenly dispersed throughout the resin. EPON Resin 2024 is recommended for use in powder coatings for appliances, metal shelving, institutional furniture and automotive parts. In addition, it can be used in thick-film functional pipe and electrical insulation coatings.

 

Benefits

  • Uniform properties from lot to lot
  • Filtered to remove particulate contaminants
  • Low in color
  • Stable on storage
  • Flows evenly and cures rapidly at elevated temperatures
  • Provides consistent cure response with a wide variety of curing agents

Processing/How to use

 

General Information

Powder coatings formulated using EPON Resin 2024 give all of the benefits traditionally associated with epoxy coatings. They provide tough and durable films which have excellent adhesion to most substrates, are highly impact resistant and protect against chemical attack.

 

The low concentration of particulates and low moisture content in EPON Resin 2024 make this a highly desirable resin for powder coatings which must produce smooth films free of surface defects.

 

The addition of the MODAFLOW to the base resin provides a foolproof technique for optimum dispersing of the flow agent in a powder formulation.

 

Identification and Classification

Chemical Abstract Service Registry Number: No number is available because EPON Resin 2024 is a mixture. The components are found in the TSCA inventory and are listed as follows:

Base epoxy resin: CAS No. 25036-25-3

MODAFLOW: CAS No. 26376-86-3

 

Formulation and Application Information

Consult Technical Brochure, entitled “Formulating Powder Coatings with EPON Resins.”

 

FDA Status

Paragraph 175.300 in Title 21 of the Code of Federal Regulations permits and regulates the use of epoxy resins such as cured EPON Resin 2024 as indirect food additives in food contact applications.

 

Curing agents and catalysts for EPON Resin coating systems are also regulated under several sections of Title 21, for example 175.300 and 177.2280, and are subject to the limitations imposed by these sections and the general requirements of good manufacturing practices. Consult these sections for specific examples.
