Universal Primers
Proven corrosion protection, simplified specification and exceptional performance across every major vessel area.
Reduce complexity without compromising protection
International® universal primers provide dependable corrosion resistance, year-round workability and a single coating platform that helps shipyards improve efficiency, reduce specification risk and support more sustainable operations.
Simplify shipbuilding without compromising performance
Today's shipbuilding projects demand faster delivery, greater efficiency and consistent quality. Managing multiple primer specifications across different vessel areas adds unnecessary complexity, increases inventory requirements and creates opportunities for costly application errors.
International® universal primers provide a smarter alternative. Designed for use across all major vessel areas, our universal primer platform enables shipyards to standardize coating specifications, streamline procurement and improve productivity, while delivering the long-term corrosion protection trusted by owners around the world.
Long-term corrosion protection
Engineered to deliver long-term asset protection, with solutions proven to perform throughout a vessel's service life.
A simpler approach to primer specification
A single primer platform can reduce application complexity by up to 80%, simplifying specification, storage and application processes.*
Helping improve application efficiency
High-solids technology helps reduce application time, paint consumption, waste and VOC emissions while improving productivity.
Decades of proven in-service performance
Intershield® 300 has been applied on more than 25,000 vessels, making it one of the industry's most established universal primers.
*Assuming preparation, handling and product changeover are proportional to the number of products used.
One platform. Three performance levels.
Whether your priority is balanced performance, premium protection or the highest level of corrosion resistance, our universal primer platform offers a solution matched to your operational requirements while maintaining a consistent application approach.

High solids technology. Lower environmental impact.
High-solids technology is central to our universal primer range, helping shipyards improve efficiency while supporting environmental objectives. By applying more coating with less solvent, these formulations reduce emissions, minimise waste and help lower overall coating consumption without compromising performance.
Key benefits:
- Lower VOC emissions
Helping reduce solvent emissions and support compliance.
- Less paint, less waste
Higher volume solids mean more coating remains on the substrate.
- Faster application
Reduce application time and improve throughput.
- Lower lifecycle costs
Long-term protection with fewer resources consumed.
Proven performance
Our universal primer technology is backed by decades of in-service experience and rigorous testing. Intershield® 300 has been applied to more than 25,000 vessels worldwide and is approved in accordance with IMO PSPC requirements for ballast tank coatings.
When used as part of a compatible coating system, it is designed to provide long-term corrosion protection throughout a vessel's 25-year design life.
