Processing/How to use


General Information

Powder coatings formulated using EPON Resin 2004 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 physical properties of EPON Resin 2004 make it a preferred resin for powdered pipe coatings. Such coatings resist sintering and cobwebbing during application to heated pipe, yet they flow out smoothly and cure rapidly with amine and substituted amine curing agents. High film integrity develops quickly which aids in production and handling of coated pipe.


EPON Resin 2004 can also be used in thin film decorative powder coatings when a tough, yet attractive surface is desired. The low concentration of particulates and low moisture content of the resin aid in obtaining a smooth coating free of surface defects.


EPON Resin 2004 is also an excellent resin for solventborne coatings where the absence of surface defects is important. Use of this low particulate content resin can lead to less stringent filtering requirements of the coating formulation.


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 2004 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, 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.


Safety, Storage & Handling

Please refer to the MSDS for the most current Safety and Handling information.


Please refer to the Hexion web site for Shelf Life and recommended Storage information.


EPON Resin 2004 is a stable material produced in flake form and packaged in 50 Ib. bags with a foil, moisture barrier lining. The product requires no special storage or shipping provisions other than to protect from moisture.


Exposure to these materials should be minimized and avoided, if feasible, through the observance of proper precautions, use of appropriate engineering controls and proper personal protective clothing and equipment, and adherence to proper handling procedures. None of these materials should be used, stored, or transported until the handling precautions and recommendations as stated in the Material Safety Data Sheet (MSDS) for these and all other products being used are understood by all persons who will work with them.
