In line with a tradition that stretches decades, the staff at Corrocoat head office in Leeds all got together on the last day before the Christmas break for the annual charity auction.
Each year a number of suppliers and contacts are kind enough to acknowledge with seasonal gifts their appreciation of the relationship with Corrocoat. It was decided many years ago that these gifts would be collected together and auctioned on the last day of business to the whole company.
So after a buffet lunch, the whole team gathered in the engineering workshop for the main event. Hosted by our CEO, Charles Watkinson, the bidding this year got off to a lively start and peaked when a number of sumptuous Christmas hampers were offered for sale.
All profits from the auction are presented to a Leeds homelessness charity called St Georges Crypt. A Leeds charity that focuses on accommodation, training and mentoring to transform the lives of homeless people. This year a grand total of £1,000 was raised and was donated to St Georges as a gesture of Corrocoat’s continued support for this worthy local cause.
Corrocoat SEL is an epoxy lining providing durable chemical protection in aggressive atmospheric conditions and immersed environments.
Corrocoat SEL is a spray-applied epoxy glassflake lining, intended for single or multi-coat application, that provides durable chemical protection in aggressive atmospheric conditions and immersed environments. Corrocoat SEL has a smooth finish and can withstand immersed temperature levels up to 900C in oil, and non-immersed levels up to 1000C. SEL also displays excellent resistance to discolouration that can occur on exposure to strong concentrations of sulphuric acid.
The coating has excellent application characteristics and edge coverage in single coats and is predominately applied by airless spray for speed and ease of application. A brush can also be used for modest areas as dictated by a particular project or on-site conditions.
Corrocoat SEL is an ideal choice in the protection of new and existing storage tanks and vessels in testing service environments including hydrocarbon service. It can also be used on structural steel, bridges, pilings decks, externals of process vessels/pipelines, jetties, ships hulls, and other marine environments.

The RRS Sir David Attenborough is one of the world’s most advanced polar research vessels. The ship was commissioned by NERC, built by Cammell Laird and operated by British Antarctic Survey. This new research platform will transform how ship-borne science is conducted in the Polar Regions. Corrocoat was asked to provide corrosion protection against seawater for a large number of seawater pipes due to be installed on the ship.
The commissioning of the RRS Sir David Attenborough is designed to keep Britain at the forefront of world-leading research in Antarctica and the Arctic. This £200m commitment represents the UK Government‘s largest investment in polar science since the 1980s.
Newly fabricated seawater pipe spools and slip-on flanges required corrosion protection against the corrosive effects of exposure to seawater.
On arrival at Corrocoat’s Leeds workshops, all machined surfaces were masked before abrasive blasting followed by a blowdown, sweep and vacuum to completely remove dust. Corroglass 600 was then applied, in multiple coats, using the Agmec internal pipe spaying method, to achieve the desired DFT.
Once cured all surface protection was removed, edges dressed and a full visual inspection completed. Thickness testing and spark testing was completed to ensure the quality of the finished coating system.
Corroglass 600 has excellent resistance to solvents, acids, and seawater, providing undercutting resistance and sliding abrasion resistance. The coating system will significantly extend the pipe’s service life.
As a supplier to the ship, and an event sponsor, Corrocoat were supplied 4 tickets to the ceremonial naming of the RRS Sir David Attenborough at Cammell Laird shipyard, Birkenhead on 26 September 2019.
A free prize draw was held to enable three Corrocoat staff the opportunity to attend this prestigious event with one of the company’s directors, and to see where their hard work ends up.
Corrocoat has launched a new underwater repair system designed for use on submerged surfaces such as structural steelwork, pilings, jetties. Based upon the well-established Plasmet range of products, the system is both fresh and marine water tolerant. The system is designed to be applied and cure whilst immersed.
The underwater repair system comprises: Plasmet UWP – an epoxy glass flake putty, Plasmet UWL – an epoxy laminate for application with glass fibre matting and Plasmet UWT – an epoxy glass flake topcoat.
Plasmet UWP is designed for ease of use and can be applied by trowel or by diver’s glove for localised repair. After 24 hours the putty can be over-coated with Plasmet UWL to provide additional reinforcement to the repair if required. The laminate is tolerant of water and will cure in six hours after which a final top coat of Plasmet UWT can be applied.
Repairs to underwater systems can be completed without the necessity for outages to replace damaged infrastructure. The system allows for immediate works to be carried out, without having to wait for spares to arrive on-site, meaning significant saving can be realized by avoiding downtime costs and loss in production.
All three coatings in the system exhibit excellent wet adhesion in excess of 9.5 MPa and have a cathodic disbondment rate of less than 1mm. Displaying exceptional salt spray resistance this system is ideal for use in industries such as oil and gas, power generation, marine, renewables, ports and water and waste where repair work is required in constantly submerged or tidal situations.
Corrocoat Fibrecoat, a high-performance glass fibre reinforced, abrasion and temperature resistant protective lining for pipelines, is now available.
Corrocoat Fibrecoat is a glass fibre reinforced vinyl ester glass-flake coating developed for use as a high-performance lining and rehabilitation material for thinned/corroded pipes and where additional tensile properties are required.
The product is applied using the Agmec airless spray equipment, this allows long pipe runs of up to 100m in length, and 1.2m in diameter, to be coated in one pass. Savings are significant and in many cases pipework can be blasted and coated in-situ without the need for expensive excavation and disassembly.
Corrocoat Fibrecoat may be applied in single or multiple layers at up to 3000 microns per coat, adding additional tensile strength to thinned/corroded pipes, whilst at the same time protecting the pipes from further corrosion.
Fibrecoat is highly abrasion resistant and suitable for application in aggressive service conditions, making the material ideally suited to sewage applications. The coating has high-temperature resistance and can be used in service conditions up to 900C immersed and 1600C non-immersed.

Plasmet ZF – a corrosion-inhibiting coating from Corrocoat is now available in a 400ml aerosol for easy application in difficult to access areas and for touch up work.
Coating with a Plasmet ZF aerosol takes much less time when compared with brush application; it also ensures that every inch of the surface is covered – even deep areas and hard to reach nooks and crannies which might otherwise be missed.
Other key benefits that users can expect are even coverage, minimal preparation; there is no longer a need to mix components on-site from separate containers, and no cleanup requirement afterward. In addition, once opened, the aerosol has a long pot life – at least 24 hours, meaning the user has time to complete a number of jobs across a site or installation.
Plasmet ZF is a tough, durable rust tolerant coating requiring minimal surface preparation, offering long term resistance to corrosion attack for applications ranging from all types of structural steelwork, tanks and pipework in many industrial sectors. Tough, durable and tolerant of vehicular traffic, Plasmet ZF can be used for protection in both immersed and atmospheric conditions.
With so many ease of use and convenience benefits, a Plasmet ZF aerosol will soon have a place in every service engineer’s tool bag – giving fast, effective corrosion protection… in an instant.

Kirloskar Corrocoat Private Ltd (KCPL) has been operating in India since 1993 using Corrocoat’s world-leading specialist anti-corrosion coating systems to protect all manner of infrastructure and customers assets in many different industry sectors.
Earlier this year KCPL, was asked to provide corrosion protection for large bore cold water inlet and outlet pipes for the Tangedco Ennore Power Project, a Government Power Project being implemented in South India. Polyglass 100, a coating developed specifically for immersed marine conditions, was specified to provide excellent corrosion protection against the corrosive threat carried by the seawater the pipes would be carryings when installed in the new plant.
KCPL was required to complete the work at the pipe manufacturer’s facilities across India including 2 pipe mills in West India and at 3 further sites In South India. Some pipe sections had to be transported by road over 2300km to the required plant locations. The project proved a test of organisational and scheduling skills to get the application teams on site as and when they were required.
The internals surfaces of the 1.3m and 1.5m diameter pipes were prepared by abrasive blast cleaning to Sa2½ to provide the required surface profile before Polyglass 100 was applied by airless spray in multiple coats to achieve a DFT of 1000µm. When the coating process was complete, spark testing was carried out to identify any pinholes or holidays in the coating surface and to ensure the quality of the final work.
After the pipes were coated they were welded together and erected on-site in final positions where the KCPL teams abrasive blasted and then coated the welded joints in-situ to ensure the continuity of the Polyglass 100 coating system throughout the pipeline.
The project was completed over a period of 6 months by a coating and application team of 20 KCPL personnel across India. In total, an incredible 51,100 sqm of internal pipe surface was corrosion protected with Polyglass 100 – quite an achievement.
Corrocoat Japan was called in to service a raw water pump at a steel plant that the company had last serviced 7 years previously in 2011. At that point, the vertical wet-pit volute pump had been in operation since 1993 without any servicing or ant-corrosion treatment and all the internal components were found to be completely deteriorated. Corrocoat Japan carried out a full refurbishment programme on the pump including the application of a suitable corrosion protection coating system and the pump was put back into service at the steel plant.
The client was very satisfied with the results and so 7 years later and, as part of the normal maintenance program in the plant, they again called in Corrocoat to carry out more work on the pump and to prepare for another 7 years in service.
Both impeller and casing were then coated with Polyglass VEHA, a modified vinyl ester filled with glass flake. Polyglass VEF provides excellent resistance to solvents, acids and de-mineralised water at elevated temperatures and provides excellent undercutting resistance and sliding abrasion resistance. The external surface of the pump was coated with Plasmet ZF a surface tolerant coating to provide good corrosion protection.
The pump was re-assembled and prepared for shipment back to the steelworks for another testing 7-year stint, fully protected by Corrocoat Japan’s advanced corrosion protection coatings systems.
