Zip E
Product reference: 3/52
Product title: Zip E
Valid from: 4th July 2006
Last reviewed: May 2019
Type
An epoxy glassflake coating, intended for a single coat application.
Suggested use
Zip E will provide cost effective, durable protection in
aggressive atmospheric conditions and aquatic immersion
environments. ZipE has excellent application characteristics
and edge coverage in single coats. Zip E has good cosmetic
appearance and gloss. Zip E may be used for structural steel,
bridges, pilings, decks, externals of process vessels/pipelines,
jetties, ships hulls and other marine environments.
Limitations
Immersed upper temperature limit is 122°F (50ºC); non-immersed temperature limit is 194°F (90°C). There is no known lower temperature limit.
Health & safety
Before handling or using this product, the material safety
data sheet should be read, and all precautions observed.
Surface preparation
Metals: For best results Grit blast to SSPC-SP10 (ISO
8501-1 Sa 2½) standard or equivalent. (For full details
refer to Corrocoat Surface Preparation Specification
SP1.) Zip E can also be applied to mechanically prepared
or water blasted surfaces or were Plasmet ZF has been
used as a primer.
Concrete: Priming is required, see Corrocoat Surface
Preparation sheet SP5, use Plasmet ECPas the primer
Application equipment
Brush or short haired roller.
Application
Airless Spray pump minimum 45:1 ratio, with an output of
at least 4 litres per minute. The pump should be fitted with a
leather/Teflonseal combination and all fluid filters removed.
Use nylon lined 10mm (⅜”) internal bore spray line with a
short 6.5mm (¼”) whip and a large bore spray gun fitted
with a swivel connector. 17 to 23 thou reversible spray tip is
recommended. Spray tip and fan pattern will vary and should
be selected to suit the nature of the work. Fluid pressure
approximately 4,000PSI depending on temperature, spray
line length, etc. Zip E should not be applied or used at
temperatures below 41°F (5ºC).
Pot life
Generally, 70-90 minutes using the standard hardener
at 68°F (20ºC). Pot life will vary significantly with
temperature.

Thinners
The performance of this product will be adversely affected by
the use of solvent based thinners. Under normal application
conditions it is not anticipated that any thinners will be
required with this product

(20ºC). Tack-free and full cure values will vary subject to
ventilation and temperature.
Cleaning solvent
For best results use Corrocoat Epoxy Equipment Cleaner
Catalyst / hardener type
Modified Amine Adduct
Storage life
2 years minimum in unopened tins, stored at 41-104°F (5-
40°C).
Color availability
White and light grey as standard. Other colors available on
request, price of material subject to color and quantity.
NOTE: This product is formulated to give optimum corrosion
resistance. Due to the nature of the polymerization process of
this product, it is not possible to guarantee color matching
or color stability. Where color stability is of paramount
importance, it is recommended that Zip E is over coated with
Corrothane AP1.
Recommended DFT
Dependent upon intended use, geometry of work and
service conditions. Zip E is normally applied to achieve
DFT’s of 8-40 mils (200-1000 microns) by applying at 10%
greater WFT’s.Single coat application is preferred but
multiple coats may be used to achieve the required DFT,
refer to data on over coating times.
Volume solids
Greaterthan 95%.
Practical coverage rate
Approximately 25 sf per gal at 20 mils (0.6 litres/m2 at 500
microns) DFT.
NOTE: This information is given in good faith, but
consumption may increase dependent on the environmental
conditions, geometry, nature of work undertakenand
the skill and care of application. Corrocoat accept no
responsibility for any deviation from these values.

Over coating
Where multiple coats are required, over coating may take
place after 3 hours at 68°F (20ºC). Wet on wet
applications are acceptable. The maximum over coating
time is 72 hours at 68°F (20ºC). Over coating times will
reduce significantly at higher temperatures and/or in
strong sunlight. The minimum overcoating time at 50°F
(10ºC) is 24 hours, refer to Corrocoat TechnicalServices
for overcoating instructions below 50°F (10ºC).
