High Performance Multi-Purpose Sealer for Zinc/Chromated Surfaces
Traditional silicate seals work in most applications with limitations. E-Seal 1000 can be applied to all E-Chrome hexavalent chromates clear, yellow and black plus all E-PASSivate trivalent chromates offering 3-5 times longer corrosion protection to white corrosion per ASTM B-117.
E-Seal 1000 does not significantly change the thickness of the plated part, works over different chromate films and is utilized in the final dip.
Equipment
Tanks should be constructed of polypropylene, PVC, Koroseal lined carbon steel or stainless steel.

Solution Make Up
Fill the tank to 2/3 of the way with water. Carefully pour E-Seal 1000 to obtain the desired concentration – avoid spattering. Wear safety glasses, gloves and apron. Add water to working level.Concentration Range Optimum 15-25% by volume 20% by volume Temperature 65-80F 70F Immersion Time 30-60 seconds 30 seconds Processing Procedure
1. Zinc or cadmium plated surfaces
2. Thorough cold water rinse will prolong the life of chromate.
a.) Optional 1% Sulfuric Acid to neutralize residual plating solution with barrel processed work.
b.) Cold water rinse
3. Immersion in E-Chrome or E-PASSivate (see respective product data sheet).
4. Cold water rinse
5. E-Seal 1000. For optimum corrosion resistance the immersion time must be kept to a minimum. Maximum immersion time – 60 seconds.
6. Hot air dry. Optimum corrosion resistance will be obtained if the temperature of the hot air is kept below 150F for hexavalent chromates.
Solution Control
The strength of the E-Seal 1000 working solution can be determined with the following procedures:
1. Pipette 25 ml of the bath into a 250 ml Erlenmeyer flask.
2. Add 2-3 drops of Phenolphthalein Indicator. The color will be pink.
3. Titrate with 1.0N Hydrochloric Acid until the pink solution turns completely clear.
Calculation: % by volume E-Seal 1000 = ml of 1.0 N Hydrochloric Acid x 5
Safety & Health
- Caution
This material is alkaline. Do not get in eyes, on skin or on clothing. Do not breathe mists. Do not take internally. When handling, wear goggles or face shield. While making up solutions, or adding to a solution, add slowly to surface of solution to avoid spattering. In case of contact immediately flush skin or eyes with plenty of water for at least 15 minutes. For eyes, call physician. Do not mix E-Seal 1000 with acidic materials or any other chemical substances.
