Navigation/Electro-optic Sensor Integration Technology (NEOSIT)

Not Available Marine coatings are the key materials used to protect metals against corrosion and obtain the full design service life from ships. Marine anticorrosion coatings have a significant economic impact and any breach in the anticorrosion coating that may occur due to abrasion or during docking must be repaired as quickly as possible. The most difficult portion of a ship to recoat and repair with anticorrosion coatings is the underwater hull because repairs must be done under water by divers to avoid expensive dry- docking. The present repair coating formulation disintegrates during application causes the water to be cloudy, blurs the diver's vision and contaminates the marine life. Foster-Miller proposes to develop a high performance, environmentally compliant, non-toxic, no VOC (100% solids) hull touch up repair coating that can be applied underwater without hindering the performance of the application team. The proposed repair coating will adhere well to underwater substrates, cure while immersed in water and have sufficient water-resistance so that it doesn't disintegrate and obscure vision during application. Our proposed ADHER repair-coating formulation will also provide good adhesion, toughness, anti-blush and water resistance properties, and will readily accept additional coatings that can be applied during dry- docking.
