Assessment under Dynamic and Static Conditions of Underwater Paint Systems for use on the Glass Reinforced Plastics (GRP) Minehunter

摘要

Twelve underwater paint systems were assessed for use on the RAN glas reinforces plastics (GRP) Minehunter. The paint systems were applied to GRP panels and tested for durability under dynamic flow conditions on the MRL rotor apparatus. All paint systems exhibited satisfactory adhesion to the GRP and would therefore be suitable for application onto the hull of the Minehunter. However, most of the antifouling paints suffered some surface deterioration during the rotor trial. The panels were subsequently immersed on a static raft to determine antifouling performance of the systems, and to compare them to identical paint systems that were not initially exposed dynamic flow. It was apparent that initial exposure to dynamic flow had some affect on the antifouling capabilities of the paint systems.
