Conventional protective coatings often fail prematurely when applied to weathered or micro-pitted metals. As documented in comprehensive metallurgical evaluations and Fourier Transform Infrared Spectroscopy (FTIR) diagnostics, mild steel structures frequently contain high levels of absorbed moisture within their surface topography bending and stretching vibrations, Even after standard surface preparation, this deep-seated moisture continues to drive internal electrochemical reactions, propagating aggressive corrosion networks and localized pitting beneath the dry paint film.
Infra Fix PU-2620-1 features a specialized molecular design that penetrates deep into the porous corrosion morphology of mild steel substrates. Upon application, it chemically encapsulates the absorbed moisture and locks down active corrosion propagation sites. By arresting the internal degradation mechanism prior to final topcoat application, the primer establishes a stable, passive baseline for long-term structural integrity.
Key engineering and performance benefits validated during development include:
Active Moisture Encapsulation: Neutralizes internal moisture pockets identified via FTIR peak analysis, stopping subsurface corrosion pathways.
Corrosion Network Arrest: Successfully seals micro-pits and complex interconnected corrosion networks to prevent lateral rust creep.
Optimized Substrate Adhesion: Establishes a highly cross-linked, durable structural anchor between compromised parent iron substrates and topcoat systems.
Field-Proven Performance: Validated through rigorous stress testing across actual high-corrosion industrial sites and controlled laboratory simulations.
With the rollout of the Infra Fix PU-2620-1 primer series, Lexus Paints & Coatings equips infrastructure engineers and maintenance units with a definitive solution to future-proof heavily degraded steel assets against premature coating failure.
