Following a successful programme of testing in NE Asia and Western Europe, Norwegian coatings company Jotun is to launch its Jotacote Universal S120 primer to the global market.

Jotacote Universal S120 is said to be the first PSPC approved single coat, solvent free system. It has been applied to a variety of vessels including 12 newbuilds, with six more under construction and an additional four projects secured.

The solution features patent pending Covallox technology that incorporate covalent bonds in its chemistry on top of the already existing hydrogen bonds typical of conventional epoxy. This offers high substrate adhesion providing durability and anticorrosive properties targeted at lifetime protection of the vessel, particularly in the ballast tanks.

Dr Erik Risberg, Global Marketing Director, Jotun Marine Coatings, said: “The response we’ve received from the market in North East Asia and West Europe illustrates the efficacy of Jotacote Universal S120 and the strong benefits it delivers to shipowners. This has been a careful process of evaluation, following an extensive development programme for Covallox technology - which has taken place over 16 years – and we’re now gearing up to take this unique product to our global customers. It is market proven in South Korea, one of the world’s leading shipbuilding nations as well as in Germany which specialises in building cruise vessels. This gives us an excellent foundation to build upon and we believe Jotacote Universal S120 can be a genuine gamechanger within marine universal primers. The application of single coat systems is more demanding, and this careful approach has enabled Jotun’s technical staff to establish robust procedures to ensure the perfect completion.”

Although solvent free definitions can vary, Jotacote Universal S120 is a ‘true’ solvent free primer. This maximises its potential to reduce VOC and CO2 emissions. It is considered that universal primers often represent 60-80% of the total paint volume on a newbuilding project which would then translate to a great reduction in VOC emissions. The single coat solvent free PSPC approved system of Jotacote Universal S120 further reduces complexity and production time improving shipbuilding efficiency by up to 43%. 

Further advantages are unlocked in terms of long-term performance, as Risberg explained: “Traditional solvent-borne coatings can become brittle over time, aging with both exposure to ballast water and the hot and humid conditions of laden vessels. However, with Covallox technology we can minimise the aging process and retain the coating’s original flexibility ensuring unbeatable durability and minimal maintenance throughout the vessel’s life cycle. This leads to compelling cost benefits, especially as, with less durable coatings, steel replacement is often necessary. But not with Jotacote Universal S120.” 

“Jotacote Universal S120 is true solvent free, conforming to the highest standards and ensuring optimal long-term performance. The three years of experience we’ve received from applications in South Korea and Germany has been invaluable. We now look forward to emulating that success for customers across the globe.”
