Marine Coatings
Phenalkamine and phenalkamine-adduct curing agents for severe service conditions: saltwater, weathering and maintenance cycles measured in years.
Marine coatings face salt spray, UV, abrasion, anti-fouling pressure and narrow dry-dock windows. Uniform's marine line is built around phenalkamine chemistry for moisture-tolerant cure and adhesion on prepared steel.

What to think about
Cure under moisture
Phenalkamines tolerate ambient moisture far better than classical amines, critical for marine field conditions.
Pot life vs cure speed
Pure phenalkamines (7040, 7041) give longer pot life; adducts (7077, 7080) shorten the cure window.
Colour budget
If a colour-critical topcoat sits over the system, 7057 (Gardner 10) is the cleaner choice.
Phenalkamine cure through a monsoon dry-dock window.
A South Asian shipyard standardised on Unilite 7041X90 and Unimide 115 for hull primer work. The moisture-tolerant cure profile helped coating work continue in conditions where classical amine systems failed cure tests.
