When the word “Coating” is used, most people think of a paint that forms into a solid barrier film.
The HRCSA Self-Priming Topcoat is an unconventional coating system which is both chemically active and elastomeric.
Traditional barrier or sacrificial barriers cure across the steel micro voids leaving areas of exposed steel between the coating and the substrate – these micro void areas are vulnerable to rapid undercutting once the barrier is breached.
HRCSA is a reacted calcium sulfonate, calcium carbonate based complex that fully wets the surface as it neutralizes acids, displaces moisture and scavenges oxygen leaving no micro voids unfilled.
The high ratio of active calcium sulfonate thoroughly wets the micro voids creating a mono-molecular layer of cations which ensure chemical neutrality and no undercutting if the coating is breached. ( The HRCSA reacted formulation’s uniqueness is what gives it this performance advantage.) <Link to Specifications>
The role and function of HRCSA calcite platelets.
Once applied, the formulation’s artificially grown calcite crystals line up like fish scales to form a strengthened film with extended pathways for moisture and oxygen.
When acidic moisture (acid rain) passes through these crystals, a minute amount of the calcite dissolves to create a neutral base liquid void of acidity at the steel substrate.
Summarily, it neutralizes acids, displaces moisture, and scavenges oxygen.
HRCSA Penetrant/Sealer + HRCSA Self Priming Topcoat = Meld
When the word “Penetrant” is used, most people think of a low molecular weight epoxy or moisture cured urethane penetrants which were primarily designed to bind up existing rust on steel surfaces and a tiecoat.
This explains why rust bleeding from connections can usually be seen < 2 years after application – the corrosion was never stopped.
HRCSA meld coat is both chemically active AND flexible.
Crevice corroded and pack-rusted joints and connections that are properly prepared (flushed, salt mitigated and dried) then pressure filled to refusal with HRCSA Penetrant-Sealer, Meld-coated with HRCSA self-priming topcoat and overcoated with same (wet on wet), creates a chemically active, flexible seal that actively stops corrosion inside the connection for years (even decades) to come.
Because the chemistry stays active in the connection allowing the structure to move without damaging the film.
HRCSA can applied by spray, brush or roller to anything Fe – including: steel of any type, as well as overcoating tightly adhered, contaminant-free existing coatings.
Pressure-Applying HRCSA Penetrant into flushed out, blown dried, cleaned corroded crevices before application of the HRCSA meld-coat.
Application of HRCSA meld coat (thick layer of HRCSA self-priming topcoat overtop HRCSA Penetrant).
HRCSA Penetrant inside tubes or enclosed areas.
HRCSA Penetrant can be fogged, or mist applied inside tubes.
Bearings, Pin Connectors, Interfaced steel
Once all connections are treated properly, the entire steel structure is overcoated with HRCSA self-priming topcoat. Single component, single coat application makes for shortest coating application times in the industry.
