Recently, more ice breaking vessels have been built due to improving world trade. Therefore, these vessels should be designed to withstand both extremely high mechanical impact and abrasion damages sustained while operating in pack ice, in addition to the very corrosive environment. In order to minimize the mechanical damage, the hulls are coated with anti abrasion and low ice friction coatings such as epoxy or solvent free epoxies. All these coatings require the use of special hot feed plural component pumps, high grade surface preparation and coating application procedures and application conditions are taken into consideration.

This study was carried out in order to establish and to verify the correct methods for the application of these coatings and to confirm the most suitable coating procedures additionally the prospect of improved workability block painting as opposed to painting at dock stage for new building. We also investigated the general physical properties characteristics such as drying times, pot life, and adhesion strength on different surface preparation grades.
