Formulation Notes
Mirror silver backing is vulnerable to alkaline attack at pH > 10, causing black-edge corrosion. This formulation operates at milder pH and incorporates an anti-fog agent.
Formulation FC-10.5-M — Mirror Cleaner (Liquid, Anti-Fog)
Specification: pH 9.0 ± 0.2; surface tension 27 ± 2 mN/m; anti-fog rating ≥ 8 hours (40°C, 90% RH). The sulfosuccinate adsorbs at the glass-air interface to suppress water-droplet nucleation, while propylene glycol remains as a sub-visible humectant film.
