Graphene Top Coat used for railway buildings.
Work commenced in mid November 2020 on railway trackside SSP’s with our world famous 10,000 hour salt spray Graphene Enhanced Top Coat.
SSP’s are essentially steel containers but they contain important electronic and electrical equipment for handling signals, points etc. Blocksil has specified and supplied the complete coating system, which includes our Rust Converter and high performance Primer as well as the Graphene Top Coat.
The application is being carried out by approved applicator Aerial Contracting. The photos show two of the locations being worked upon.
Local village anti-graffiti programme.
On the outskirts of Lichfield, Blocksil’s home city, is the village of Whittington (population of under 3,000). Like most villages, towns and cities, it is not immune to graffiti, especially on road signs. Our Chief Technical Officer, who lives in the village, offered to coat the village name signs in one of our transparent anti-graffiti coatings. So now any graffiti will either not stick in the first place or it will wash off with water.
All Blocksil anti-graffiti coatings are permanent and one range is available in a number of colours.
Aside from our CTO, Whittington’s other claim to fame is as the burial site of Thomas Spencer, co-founder of Marks & Spencer plc. He died in 1905 and is buried at St Giles Church, Whittington. There has been a church at St. Giles since the 13th Century, though it was destroyed by fire in 1760. It was rebuilt in Georgian style using locally sourced sandstone.
11,800 hours salt spray and still going.
Our Graphene Enhanced Top Coat MT has been on continuous salt spray testing for some months now. This week we went past the 11,800 hour mark with no corrosion, even with just 35 microns of coating. 
Salt spray testing, ISO9227:2017, is particularly useful for detecting discontinuities such as pores and other defects in coatings. The testing is suitable for checking that the quality of a metallic substrate is maintained. We are going to run the tests to destruction / failure of the coating.
To give you a guide, most automotive paints are tested to 1,000 hours, with 5,000 hours being considered exceptional.
The start of our Technical Support Fleet.
September 2020 and we take delivery of the first in our proposed fleet of Technical Support Vehicles.
Technical Support Vehicle #1
As part of the technical support and development service we offer our clients, we often need to visit sites located around the UK. And as we need to have with us a wide range of PPE for the many industries we work with, plus samples, application and test equipment, having a suitable vehicle to travel in makes sense.
This first vehicle is going to be put to good use in the coming months as our clients and industry in general start to build after the Coronavirus lockdown.
Blocksil – always looking to the future.
Blocksil supports the Ecclesbourne Valley Railway.
Mid-August 2020 and we supplied our Rust Converter and corrosion resistant coatings, free of charge, to the Ecclesbourne Valley Railway. We supplied the coatings (having used our technical expertise to specify them) for the refurbishment of the railway crossing gates at Wirksworth Station, a heritage station that is part of the Ecclesbourne Valley Railway in Derbyshire.
The gates were badly corroded and dirty, so after a high power jet wash to clean them up and remove any loose debris and rust, the rusty areas were treated with our highly commended Rust Converter. The Rust Converter converts Iron Oxides to Iron Phosphate which can then be overcoated.
The coating system chosen comprised a high build undercoat and a high solids Polyurethane top coat. And what a difference the coating has made to the gates.
Trust in Blocksil.

More successful testing for Blocksil’s corrosion resistant Graphene Enhanced Top Coat.
To achieve the highest possible level of safety in trains, all materials and components must meet strict fire protection requirements under EN 45545-2:2013. Different areas of the train are assigned different categories, or Requirement Sets. We have been subjected to tests to satisfy set R7, which covers the exterior. It should be noted that we are just about at the pass level for the more stringent R1 interior level.
There are three Hazard Levels (HL1 to HL3) with HL3 being the highest level. It makes the highest demands on the materials used. Blocksil Graphene Enhanced Top Coat MT has satisfied the requirements for HL3. The testing for EN 45545 includes spread of flame, heat release rate, smoke and toxicity.
The full report can be read here.
Note that we deliberately had the coating tested on top of fibre board so the fire testing was a test of the coating itself.
Blocksil performs again.
The Unit 4 Distillation Column at Haltermann Carless Harwich Refinery has just been reinstated after refurbishment.

Externally the column was stripped of its lagging, grit blasted and inspected before application of a Blocksil supplied high temperature paint system.

Anti-Fouling Coating in action…
Although we at Blocksil know our coatings are good and do what they say, it is always good to get client feedback, especially with a new product.
The Blocksil Anti-Fouling Coating was applied to a privately owned yacht in June 2019 to assess the coating’s performance. The yacht owner took it out of the water in May this year. Did the coating work? Of course it did.
The yacht Frankie B 3 was lifted out of the water for jet wash and hull inspection on 27th May 2020. The marina boatyard operatives used a high pressure jet wash to remove dirt and fouling off the hull. The rudders were inspected and found to be in good clean condition. Using hot water and non-abrasive household cleaner the rudders were lightly freshened up with minimal physical manual effort. The final inspection revealed no reduction of the protective paint finish applied by Blocksil.

Avanti Communications approve our Graphene enhanced Top Coat.
Avanti Communications plc is a world-leading provider of agile, secure and pioneering satellite technology across Europe, the Middle East and Africa.
Their sites around the world are often in remote or high humidity areas, which results in rapid rusting of the satellite dish structural steelwork. The conventional approach to painting has been used for years but rarely lasts 12 months in seaside or tropical locations. Working with the specialist coating contractor Aerial Contracting, Blocksil has provided a long term solution with it’s Graphene Enhanced Top Coat MT.
In combination with carefully chosen pre-coats, the Graphene enhanced Top Coat has a 15 year product warranty.

Blocksil protects Banksy
…and saves Christmas.
Blocksil donated a high performance transparent coating and our time to apply it over the Banksy mural which appeared in Birmingham in December 2019.
The coating is designed to preserve the mural and the underlying brick by both penetrating into the brick and subsequently covering the mural. Thus any future attempts to add to the Banksy will be thwarted. And the coating will provide a barrier to weathering.

Blocksil Expansion
Blocksil has had an exciting 2019, with new products coming on stream, new projects and new clients.
The new clients we’ve taken on are requiring us to keep a buffer stock of their most commonly used coatings. And the new coatings we’ve got coming through for early 2020 are going to need increased laboratory space.
So when an industrial unit in the nearby town of Fazeley became available for us to rent, we jumped at the opportunity. Fazeley is within the District of Lichfield and dates back to the 12th Century, though these days is perhaps better known for Drayton Manor Theme Park.
Affording us with warehouse space, a dedicated laboratory and enough office space to set aside an area for a training / meeting room, this move is the next logical step in our development.
More information and photos will be made available when we move in ready for the start of 2020.

Wednesday 10th July 2019 and graphene enhanced roof coating is launched at the Advanced Materials Show in Telford, UK.
Advantage Graphene launch at the AGM stand, Telford, UK
Distributed in the UK for metal roofs under the Alltimes Advantage brand name, our already high performance Top Coat MT metal roof coating has taken the next giant leap forward.
Alltimes Advantage Graphene is still the same lightweight, re-coatable roofing system that roofers have come to depend on, but the addition of graphene creates a ‘tortuous pathway’ for water molecules, oxygen and salt to pass through. Put simply, it forms a barrier that is virtually impenetrable, giving unparalleled protection for a metal roof against corrosion but without impairing the moisture curing properties.
In its purest form, graphene has a molecular structure comprising of a single layer of carbon atoms bonded in a hexagonal structure. It is 200 times stronger than steel and it is the thinnest known material in existence. It can vary in the number of atomic layers but it typically has a 1nm to 10nm thickness with 1µm to 15µm lateral diameter, resulting in aspect ratios of up to 1:1000 and surface areas up to 700m2/g. To put that into context, just 1g of graphene in this form has a total surface area of over 350m2!
The idea behind adding graphene to our roof coating came from Blocksil’s Chief Technical Officer. Subsequent collaboration with Applied Graphene Materials Ltd (Redcar, UK), who specialise in adapting particulate forms of graphene for dispersion into different materials, took us to a workable coating.
Applied Graphene Materials manufacture their graphene synthetically from sustainable sources and so achieve a very repeatable product. They do not start with graphite nor use any oxidation procedures during graphene production and therefore their graphene is almost completely free of graphitic impurities, graphene oxide or transition metals.
The Advantage Graphene system is the result of extensive product development and a rigorous testing programme. It has been successfully tested to ISO 9227:2017 neutral salt spray for 5,000 hours. This has ultimately produced a system that delivers an industry leading level of anti-corrosion performance and life expectancy for industrial and commercial roofs.
Due to its exceptional corrosion resistance performance, Advantage Graphene is being offered with an unparalleled 30 year product warranty.
Rail Live 2019 and a successful exhibition.
June 2019 and the Porterbrook Innovation Hub was a resounding success.
The Innovation Hub was a stationary train that Porterbrook had taken out of service and made over. Companies were invited to submit innovation products to Porterbrook and 25 were selected to display these products. Blocksil was one of those chosen.
Porterbrook Innovation Hub at Rail Live 2019
On our stand within the Innovation Hub train we displayed our easy clean coating CleanProtect and our thermal dissipation coating Therma-Light. Both coatings were well received with most interest being shown in Therma-Light.

UK Concrete Show 2019
Blocksil successfully exhibited at the UK Concrete Show on March 20th and 21st and we showed off our Power Floated Concrete Sealer.
We had a sealed screeded panel on display on which we placed beetroot & vinegar as well as engine oil. The unsealed screed was permanently stained but the sealed screed resisted the efforts of the vinegar and oil to penetrate it.
Also on display was one of our other concrete products, a transparent coating that impregnated the screed by 10mm to 15mm. This impregnation allows the concrete screed to breathe yet prevents moisture from entering the screed, thus preventing algae and dirt build up.

The Blocksil team
New UK roofing coating distributor appointed
Blocksil announced on March 1st 2019 the appointment of Alltimes Coatings as the UK distributor of our latest generation high performance, hybrid roof coating system.
Fully overcoatable, this system is the next generation of pitched roof, flat roof and gutter coating, moving on from the system we introduced to the UK roof coating market a couple of years ago. Both moisture tolerant and surface tolerant, the system can even be used to recoat over worn out silicone roof coatings.
The flat roof and gutter coatings are usually supplied with fibre reinforcement for added tear strength.
