Reducing Navy Fleet Maintenance Costs with High Solids/Solvent-Free CoatingsUsing Plural Component Spray Equipment

摘要

This paper presents the results of a study performed by the Naval Sea Systems Command (NAVSEA)and the Naval Research Laboratory (NRL) concerning the use of four different types of pluralcomponent spray equipment systems and their effectiveness in reducing fleet maintenance paintingcosts. Results of the study indicate that plural component spray equipment yielded a significant costbenefit of approximately 30% as compared to conventional airless (single feed) spray equipment for theapplication of the same two-component, high-solids epoxy paint systems. The initial one time cost ofpreserving tanks with high solids epoxy paint systems applied with plural component spray equipmentwas found to be slightly higher (～10%) than the application cost of a two component solvent basedepoxy paint (MIL-DTL-24441) using conventional airless spray equipment. The increased cost was dueprimarily to higher coating and solvent disposal costs.
