Compositions based on EPON™ Resin 828 and EPIKURE 3282 cure readily at room temperature. The pot life of such compositions is highly dependent on the volume of the mixture, temperature, amount and type of filler loading, and, to a lesser extent, the presence of a reactive diluent. An indication of the reactivity of several unfilled systems under varying conditions is presented in Table 1.
EPIKURE Curing Agent 3282 is normally used at a weight ratio of 20 parts per 100 parts of liquid epoxy resin. Thin sections, where exothermic heat is readily dissipated, require 4 to 8 hours for the composition to cure to handling strength. The composition reaches full cure after 4 to 7 days. Thin sections may be cured rapidly at moderately elevated temperatures, but thick sections should be allowed to exotherm before heat is applied. The maximum thickness recommended for an unfilled composition is approximately 1/2 inch. Maximum high temperature properties are obtained with a post cure of about 2 hours at 93 to 121 °C.
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. EPIKURE Curing Agent 3282 should be stored in tightly sealed, completely filled containers of metal, glass, or polyolefin plastic at normal room temperatures. The curing agent may darken during long-term storage, the extent of color formation depending on storage temperature and exposure to air. 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. Information and MSDSs on non-Hexion products should be obtained from the respective manufacturer.
Available in quart, gallon, 5 gallon, and 55 gallon drum sizes.
