Sparc ecosparc additive + HydroGraph FGA-1 fractal graphene in protective coats.

HydroGraph case study (water-based ecosparc, ISO 9227 NSS), company figures:

• scribe-creep cut 60% at 480 h, 39% at 960 h, 59% at 1,680 h vs unmodified
• blistering reduced from 960 h; FGA-1 best of the grades they ran at 1,680 h
• scribe ~0.27–0.28 mm at each interval in that writeup

Apr 2025 HydroGraph PU-topcoat note (separate): 0 / 0.05 / 0.1 / 0.5% in commercial PU; abrasion / scratch / UV % are that release.

Sep 2026 Sparc recap: solvent-based ecosparc + FGA-1, 25% better scribe creep under ISO 12944-6 C5-VH vs unmodified; 25-week / 4,200 h cyclic test then due Nov 2026. LOI Mar 2026; supply contract still “subject to” that run.
