Extremely low permeability rate with micro-flake ECR glass.

Corrocoat coatings are specified for applications as diverse as tank and vessel linings, pipeline coatings, concrete paints, structural steel protection, and refurbishment of pumps, valves, containers, filters, etc. ECR glass flake provides better qualities than standard glass flakes and in conjunction with highly modified resin systems provides a very low permeation, mechanically strong, tough, and abrasion-resistant coating with outstanding long-term performance.

Corrocoat glass flake coating material

Excellent adhesion strength, better than any other generic coating type.

●A high binder effect is brought about by resin due to high glass flake composition.
●High solids coatings – in many cases approaching 100% – have an extremely low VOC content.

Coating materials vary quite significantly; a coating that is filled with flaked glass offers superior protection thus, reduce the permeability of the coating system.
The material that offers the best all-around properties is corrosion-resistant glass. Because of this, most flake-filled coatings are formulated using glass flake.
Corrocoat products are formulated using micro flakes ECR glass that provides extremely impermeable and high bond strength.

Corrocoat Coating Material

A low shrinkage rate during cure is obtained due to the flakes of glass preventing movement of the resin binder during the curing process

Generic Coating Material

A general coating material has a large shrinkage rate at the time of curing, low resistance to undercutting .

Exellent Abrasion Resistance
Increase in abrasion resistance due to the high aspect ratio of the glass flake.

The resin beneath the glass flake is protected and once the surface resin has been removed, in order to further abrade the composite the glass flake has to be eroded away.
This results in an abrasion resistance much closer to that of the filler than that of the binder.

Coefficient of thermal expansion similar to low carbon steel

A similar coefficient of thermal expansion arises because of the compound expansion between the resin (with a higher rate than steel), and the glass with a lower expansion rate when blended in the correct proportions.

Machinable after curing

It has the same machinability as metal and can finish the construction surface with the required accuracy.

Corrocoat glassflake coatings

Corrocoat products are formulated with micro flakes ECR glass. The flake provides Improved permeation resistance, Isotropic mechanical reinforcement, and Improved heat and dimensional stability. The hardness of the glass offers mechanical reinforcement, as well as improvements to wear resistance.

Comparison of glass flakes
Corrocoat Coating Material

The glass flakes used by Corrocoat are ultrathin,
have little variation, and do not contain impurities.

Generic Coating Material

The general purpose glass flakes are thick, not
uniform and contain impurities such as calcium

Coating material with low Vapour Transmission

The flaked glassfilled coating systems provide a long tortuous path through the binder in order that corrosive ions traveling through the permeable binder have to travel a much greater distance. The size of the flake, i.e. the diameter is what determines how far in a lateral direction corrosive ions have to travel, also the symmetry of the flakes.

[ Path Length for Moisture Vapour Transmission ]
Corrocoat Coating Material

Generic Coating Material

The tortuous path properties are approximately twenty times the path length of an unfilled binder. The higher the aspect ratio the greater the path length.


Compared to other coating materials, Corrocoat’s “Polyglass VE” has a vapor penetration rate of 0.000027, and “Coroglass 600 Series” has a vapor penetration rate of 0.000060.

Corrocoat products are the first choice.

Corrocoat products are perfect for withstanding harsh operating environments. Our unique high-performance composites and coatings not only fight against corrosion but also prolong the life of metals and machinery.
