Anti-Corrosion Coatings – Graphene Enhanced Top Coat MT

Developed from one of our construction coatings, this solvent free hybrid coating is a one coat system.

And now with Graphene added we can achieve 11,800 hours salt spray (ISO9227:2017)!

Moisture and surface tolerant, the coating cures without application of external heat so can be used on site. What do we mean by surface tolerant? It will bond to rusty steel so long as all loose rust debris has been removed – St3 is the designated standard.

In a highly exposed situation, Blocksil can recommend and supply an excellent Rust Converter as well as project specific, compatible primers.

The Graphene Enhanced Top Coat MT can be applied from near 0⁰C to 60⁰C, thereby giving the applicator a very wide application window. Application of the coatings is by spray, brush or roller. And the steel surface to be coated can be slightly damp as the coating has some moisture tolerance. 

Available in a range of colours, it takes a number of hours to fully cure but it won’t allow rain through pretty much as soon as it is applied. For more detailed and application specific instructions, please contact Blocksil for advice.

With a typical dry film coating thickness of 200 microns the Graphene Enhanced Top Coat MT on its own will give 10,000 hours of QUV testing. A typical uPVC as a comparison may achieve 500 hours and epoxy paint some 250 to 300 hours.

The QUV accelerated weathering tester simulates outdoor weathering by exposing the coating or item under test to alternating cycles of UV light and moisture at controlled, elevated temperatures.

The testing of high moisture levels on paints or coatings is important as penetrating moisture may cause damage such as blistering. So having a realistic acceleration of outdoor moisture attack as part of the testing is essential.

The Graphene Enhanced Top Coat MT has also been successfully fire tested to BS476-3:2004, CEN/TS1187:2012 – Test 4 (including EN13501-5:2016 – Test 4). Perfect pass. No ignition, no surface spread of flame and no penetration.
In addition, for the rail industry, it has been tested to EN45545-2:2013, R7 and achieved rating HL3.

Approved for use by communication companies RTÉ and Avanti Communications Group, our Graphene Enhanced Top Coat MT is very definitely the future of corrosion resistant coatings for exposed and aggressive sites.
