Product title: Corrocoat EA

Valid from: 30th December 1999

Last reviewed: May 2019


A viscous, solvent-free, high build, two pack epoxy coating with excellent
erosion resistance, toughness and outstanding anti-corrosive properties.

Suggested use

Ideally suited for brush application to areas that are to be
subjected to seawater or other aqueous immersion. The
coating also possesses resilience and good chemical


The material does not adequately cure below 41°F (5°C). It
may be applied at such temperatures, but a measure of
post curing at 59°F (15°C) or above will be necessary to
achieve optimum properties.

Health & safety

Read Health and Safety Data Sheet before handling this
material. Avoid contact with skin or eyes. Do not ingest.
Wear protective clothing and goggles. Ventilate confined
spaces. The base and activator materials are not particularly
hazardous and are safe to use provided good hygiene and
working practices are observed.

Surface preparation

For optimum performance under immersed conditions the
product should be applied to surfaces, grit blasted to
SSPC-SP10 (ISO 8501-1 Sa 2½) or equivalent. For full
details refer to Corrocoat Surface Preparation SP1 or

Application equipment

Stiff brush or trowel.


Two or more coats should be applied in coats of up to 40 mils
(1000 microns).

Mixing ratio

100pbw: 28.91 act

Mixing procedure

The material is supplied in kits consisting of the base
component (large tin) together with an appropriate amount
of activator.An additional component,(AdhesionPromoter)
can also be supplied. Mix the base and activator components
thoroughly, until the material is homogenous in color and
consistency. Then immediately prior to application the
Adhesion Promoter, where used, should be added and
mixed well.

Pot life

1 hour 45 mins at 68°F (20°C).

VOC level

0.12g per litre.

Theoretical spreading rate

36 sf per gal (0.9m² per litre) at 1mm DFT

Minimum overcoating times

As this product contains no solvent, minimum over-coating
time is not important except in avoiding disruption and drag
of the previous coating.

Short overcoating times, as opposed to long overcoating
times, are recommended for optimum intercoat adhesion
properties. In order to check that surface drag is not likely
to occur, a finger or thumb can be used to pull the surface
and where movement is observed, a longer period should be
allowed before overcoating. As a guide, minimum overcoating
times will generally be as follows:
Temperature Time
54°F (12°C) 12 hours
68°F (20°C) 10 hours
86°F (30°C) 8 hours

Maximum overcoating

To achieve intercoat adhesion, it is essential that the
maximum over-coat times are strictly adhered to. The
maximum overcoating times are as follows:
Temperature Time
54°F (12°C) 72 hours
68°F (20°C) 48 hours
86°F (30°C) 24 hours

Curing times

In order to achieve the full properties of this material, a period
of 3 days at 68°F (20°C) should be allowed before service.
Where chemical or erosive forces are likely encountered, a
period of 7 days cure should be allowed. However, due to
the cure action of this product, the coating can be put to light
aqueous service as soon as the product has gelled. This
should generally be in accordance with the minimum
overcoating time. Product will then continue to cure in

Time to achieve full cure

7 days at 68°F (20°C) or 4 days at 86°F (30°C)
NOTE: Cure below 50°F (10°C) will be slow, exposure to
higher temperatures 59-95°F (15-35°C) will improve the
rapidity and degree of cure achieved. High humiditywill
extend cure times


The product should not require thinning. The use of solvent
thinners can lead to solvent entrapment in the film, which will
adversely affect performance.

Clean-up solvent

A blend of xylene/n-Butanol at 4:1 v/v may be used.
be used.

Storage life

2 years minimum in unopened tins, stored at 42-104°F (5-
