Knowde Enhanced TDS

Identification & Functionality

Product Type: 2K (2 component) Coating,
Sealer
Technologies: Ready-to-Use Products
Product Families: Ready-to-Use Products — Paints & Coatings
Primers & Sealers

Features & Benefits

Ready-to-Use Product Features: Corrosion Resistant,
Excellent Performance,
Excellent Salt Spray Resistance
Product Highlights: Sealer for Post forming High Corrosion Resistance for Zinc/Chromated Surfaces
Traditional silicate seals will immediately display white corrosion in salt spray testing after a part is plated and then formed.
E-Seal 1002 does not significantly change the thickness of the plated part, works over different chromate films and is utilized in the final dip.
E-Seal 1002 offers self-healing properties similar to a hexavalent chromate.
The end user can zinc plate a part and post form the part at a 90 degree bend. Perform salt spray. The first signs of white rust are typically 144 hours on post formed parts. Previously the white corrosion would happen in 2-24 hours.
Equipment
Tanks should be constructed of polypropylene, PVC, Koroseal lined carbon steel or stainless steel.

Properties

Technical Details & Test Data

Technical Details: Solution Make Up
Fill the tank to 1/2 of the way with water. Carefully pour E-Seal 1002 A and E-Seal 1002 B to obtain the desired concentration – avoid spattering. E-Seal 1002 A and E-Seal 1002 B are added at a 1:1 ratio. Wear safety glasses, gloves and apron. Add water to working level.

Concentration
E-Seal 1002 A Range Optimum

10-40% by volume 20% by volume

E-Seal 1002 B 10-40% 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 1002. 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.
Analysis is by refractive index: Refractive index X 4 = % of E-Seal 1002

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 1002-A and E-Seal 1002-B with acidic materials or any other chemical substances.

Packaging & Availability
