Wax Emulsion Corrosion Inhibitors
E-Tec 521 provides additional protection over all types of plating, including cadmium and zinc. The dry film lubricating and release characteristics of this product make it an ideal mold release for gold leaf and a good joint lubricant for umbrella-type television antennas. In addition, E-Tec 521 can be used as a dressing on rubber, plastic and leather or to provide surface protection and enhance the appearance of interior wood paneling.- Advantages
- Excellent corrosion control
- Superior dry film lubrication
- Enhances appearance of most surfaces
- Effective on a wide variety of substrates
- Provides medium gloss dry film (buffable)
- Nonflammable
- Easy to apply
- Easily diluted and mixed
- Excellent coverage
- Easy to remove

- Applications
To achieve effective adhesion, apply E-Tec 521 to surfaces that are completely free of oils, greases, acids, soaps and other foreign materials. The presence of water, unless excessive, will not interfere with adhesion or film forming characteristics. Parts must be dried before stacking.
E-Tec 521 is a low viscosity liquid and is applied by any method or technique to the particular operation – flow coat, roll coater, mechanical wipe, immersion or spray.
Care must be taken to avoid spraying a dry or partially dry pattern, since a dry spray will dull the final gloss. The ideal spray gun is one which combines a comparatively high capacity air cap with a low capacity nozzle, resulting in a large volume of air mixed with a relatively small volume of material. Internal and external air mix spray techniques are satisfactory for E-Tec 521 application as is airless spray. In all cases, the atomization air pressure should be kept high, from 65 – 75 pounds. Avoid inhalation of product in spray application.
Working dilutions of E-Tec 521 should be determined by the end user. E-Tec 521 can be diluted with tap water; however, if the local water is very hard, dilute with deionized water. For maximum protection and durability, use full strength.
