Objective:
This project will evaluate and compare Navy coating systems using single component (1k) oxsol-free polysiloxane topside coatings meeting MIL-PRF-24635F Type V, Comp. 1 requirements to systems using traditional
two-component (2k) polysiloxane coatings.
Summary:
New environmental restrictions prevent some paint facilities from spraying coatings including oxsol in the formulation. To address this, manufacturers have changed the coating formulation of 1k systems to not include oxsol. The benefits of 1k topcoats include reduced mixing errors associated with traditional 2k polysiloxane coatings that can lead to early onset coating failures such as cracking and flexibility issues. Additionally, unused, mixed 2k coating must be disposed of, while 1k systems can be resealed and used later resulting in less waste. Despite these benefits, concerns still exist for the corrosion protection provided by coating systems using thinner oxsol-free 1k topcoats. This program will compare 1k and 2k polysiloxane systems by evaluating production rates when switching to a 1k topcoat, reduction in material waste, and coating performance focused on corrosion protection, adhesion, flexibility and UV resistance.
Key Deliverables / Benefits:
Benefits include:
- Elimination of oxsol (PCBTF) solvent from paint coating
- Elimination of cracking on substrates prone to cracking due to flexing of the substrate
- Reduction of waste
- Potential for use in locations where oxsol-containing products cannot be utilized due to
- environmental regulations.
Deliverables include:
- Document production rate and waste differences of 1k and 2k polysiloxane coatings
- Evaluate coating performance comparing 1k and 2k coatings
- Final report for shipyards
