General Information

EPI-REZ 6006-W-68 is a waterborne dispersion of an epoxidized ortho-cresylic novolac. The representative structure is as follows:

 

EPI-REZ 6006-W-68

 

EPI-REZ 6006-W-68 can be cured with most conventional curing agents to give polymers with high crosslink density. These cured materials provide high heat stability and superior chemical and solvent resistance. The following table illustrates that performance of EPI-REZ 6006-W-68 when cured for 20 minutes at 250 °F with various EPIKURE™ Curing Agents. Formulation D, with dicyandiamide/2-methyl imidazole (2-MI), was cured at 350 °F for 20 minutes. These thin films (1 mil) on steel Q panels show very good hardness and chemical/solvent resistance as expected for a highly functional resin.

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.

 

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. In general, these products should be lightly and thoroughly agitated before use to ensure uniformity.

 

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.
