Long-term Water and Humidity Resistance, Adhesion To Damp Concrete
Clear paints, enamels and primers for metal, concrete or masonary can be formulated with EPI-REZ™ 5522-WY-55. EPI-REZ 5522-WY-55 Resin is a 55 percent nonvolatile dispersion of a modified 1002 type epoxy resin in water and 2- propoxyethanol
Application Areas/Suggested Uses
This polyfunctional epoxy resin dispersion is intended for use in ambient cure, two-component, waterreducible epoxy coatings formulated for applications requiring a high degree of chemical and corrosion protection. Although EPI-REZ 5522-WY-55 exhibits good compatibility with several amine functional water reducible converters, it is suggested for use with water reducible EPIKURE™ 8290-Y-60 Curing Agent.
EPI-REZ 5522-WY-55 Benefits
- Rapid room temperature cure
- Low volatile organic content (VOC)
- Good paint stability
- Performance versatility
- Long-term water and humidity resistance
- Corrosion resistance over a variety of substrates
- Adhesion to damp concrete
EPI-REZ 5522-WY-55 General Information
Coatings formulated with EPI-REZ 5522-WY-55 Resin and EPIKURE 8290-Y-60 Curing Agent can be applied to a variety of substrates. These coatings exhibit very strong adhesion and long-term protection. Adhesion is particularly good over damp concrete, an exclusive feature of waterborne epoxy systems. This resin combination may be formulated into sealers, primers and low to high sheen topcoats for various industrial maintenance and specialty architectural applications. EPIKURE 8290-Y-60, the water-reducible amine adduct recommended for cure of EPI-REZ 5522-WY-55, is a highly reactive hardener. Therefore, certain formulating parameters must be considered in order to achieve maximum performance from these coatings.
The theoretical stoichiometry for this resin system is 79.5 percent epoxy to 20.5 percent curing agent based on resin solids. However, it is recommended that coating stoichiometry be based on intended end uses, since a wide variety of performance properties may be obtained through variation of the epoxy/hardener ratio. As illustrated in Figures 1 and 2, a high degree of hardness development and solvent resistance is achieved at a ratio of 75 percent epoxy to 25 percent curing agent based on solids. For flooring applications, this ratio offers the optimum required physical properties. For a broader spectrum of performance, comparable to a conventional solvent-borne epoxy coating, an 85/15 epoxy to curing agent ratio is suggested. Ratios containing still higher epoxy levels are recommended for applications requiring a high degree of corrosion and humidity protection. EPI-CURE 8290-Y-60 Curing Agent levels greater than 25 percent of total resin solids are not recommended due to the short pot life and adverse effects on water and acid resistance.

EPI-REZ 5522-WY-55 Safety, Storage & Handling
Please refer to the MSDS for the most current Safety and Handling information.
Please refer to the Momentive website 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 on to 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. Information and MSDS’s on non-Momentive products should be obtained from the respective manufacturer.
Available in quart, gallon, 5 gallon, and 55 gallon drum sizes.
