"Mold And Mildew Investigation and Testing of Navy Interior Coatings"

Picture for "Mold And Mildew Investigation and Testing of Navy Interior Coatings"
Available for download

Mold and mildew growth within Navy ships is a significant issue across the fleet. To investigate this issue the Environmental Security Technology Certification Program (ESTCP) and the Strategic Environmental
Research and Development Program (SERDP) funded an investigation into the prevalence of mold in the fleet, with the end goal of developing solutions to remediate and prevent future mold growth. Thus
far, mold and coating data was collected from 26 ships across 6 geographic locations. These mold samples have been analyzed to determine the most common species and highlight those that are toxigenic.

Mold and mildew within Navy ships is a significant issue across the fleet. In 2021 a program was initiated to characterize the extent of the issues and develop mold remediation and preventative processes and technologies. This paper will review the findings of ship inspections performed to determine the extent of mold issues across the Navy and present data on the development and testing of Navy interior coatings with fungistatic additives. In this effort, 26 ships were inspected and sampled across 6 naval bases. The ship inspections determined the most common ship spaces for mold growth, recorded environmental contributors to growth, and non-destructively tested coating characteristics of mold affected ship areas. Additionally, mold samples were taken for laboratory DNA analysis. The findings of the DNA analysis will be presented including common mold genera and species, differences between geographic locations,
and the presence of molds that can be considered respiratory hazards. Using this data, the team is working alongside industry partners to develop fungistatic additives for common Navy interior coatings. Fungal inhibition testing of the new coating is ongoing with additional testing to be performed in the future. Additionally, ship demonstrations of the new technology are planned for completion in 2023.

(Case Studies) Crisis Management for Construction Projects

Product Number: 43-COAT_DEC21
Author: Dr. Akram Saad
Publication Date: 2021
$20.00

Construction companies will experience a crisis at some point during its existence.
This is especially true for construction companies, where it is not a matter of “if” one will happen but “when” it will happen. A crisis is the sudden occurrence of any unplanned or unexpected event that causes harm to the project /company, employees, or the public. The crisis could be a medical/safety emergency, a natural disaster, or personnel crisis dealing with unethical or illegal activities.
Construction companies must always operate with a “better safe than sorry” mindset. A proactive way to do so is to ensure that there is a crisis management plan in place.

(Coating Formulation) Coatings on the Edge of Forever

Product Number: 12-COAT_DEC21
Author: Carl Reed / Kat Coronado
Publication Date: 2021
$20.00

A continuing problem with coatings applied to sharp edges of a structure is the corrosion that often develops at the apex of the edge. The conventional wisdom is that the reduction of film thickness, due to coating pulling away at the edge during the curing of the coating, is the primary cause for the onset of corrosion. This theory, however, is not necessarily correct, both from a mechanistic and practical point of view.
