General Information 

EPIKOTE 5003-W-55 contains reactive epoxide functionality. Water dispersion or water soluble curing agents which react with epoxide groups or promote self-polymerization are recommended as cross-linking agents for EPIKOTE 5003-W-55. Such curing agent types include dicyandiamide, polyamides, and aliphatic and aromatic amines.

 

Upon evaporation of water, EPIKOTE 5003-W-55 coalesces to form a clear, continuous, tacky film at ambient temperature. In baking applications, EPIKOTE 5003-W-55 in combination with a suitable cross-linking agent will form a clear, highly cross-linked, tough, chemical resistant film.

 

EPIKOTE 5003-W-55 promotes wetting and adhesion to fiberglass, polyester, nylon, and inorganic mineral fillers. It is recommended as a surface treatment, binder or adhesion promoter in applications involving these and many other substrates.

 

Advantages associated with EPIKOTE 5003-W-55 when compared to standard bisphenol A base epoxy resin include improved elevated temperature performance, increased water and solvent resistance, and improved chemical resistance.

 

EPIKOTE 5003-W-55 contains no organic solvent and is completely water reducible. This dispersion is thixotropic.

Safety, Storage & Handling

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

  

For ease of handling and optimum shelf life, epoxy dispersions should be stored in tightly sealed containers at temperatures between 50 °F (10 °C) and 100 °F (37.8 °C). Do not allow the product to freeze. To prevent skinning or surface drying, do not leave the product uncovered for extended periods of time. If the need arises to store partially filled drums, replace the plastic top-sheet onto the surface of the liquid product.

 

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. Questions and requests for information on Hexion Inc. ("Hexion") products should be directed to your Hexion sales representative, or the nearest Hexion sales office. Information and MSDSs on non-Hexion products should be obtained from the respective manufacturer.
