Chousa Srl

What Chousa Srl does

Chousa Srl is an Argentine industrial surface treatment company founded approximately 68 years ago and headquartered in Ciudadela, Buenos Aires. The company specializes in anti-corrosion coatings applied to fasteners and metal components, serving industrial manufacturers across ten verticals including oil and gas, renewable energy, electric power, mining, agriculture, electric vehicles, transportation, white goods, construction, and general industrial applications. With an employee base in the 51–100 range, Chousa operates a single production facility in Buenos Aires and runs a sales-led B2B model with quote-based engagement.

Its core technology is the proprietary LAURENTCOAT® zinc flake coating system, developed over more than 40 years, with variants including solvent-based LAURENTCOAT® 565 (chrome-free), water-based LAURENTCOAT® 676, LAURENTCOAT® 787, and the black-finish LAURENTBLACK®. The portfolio is complemented by electrolytic zinc plating, zinc-nickel alloy coatings (10–15% nickel), the TRICOAT 342 trivalent chrome-free passivator, zinc and manganese phosphate treatments, and thread-locking solutions including the distributed PRECOTE® microencapsulated adhesive (developed by Germany's Omnitechnik) and NYLOK® patches. Technical claims include controlled 5–12 micron coating thickness that preserves thread tolerances, non-electrolytic application eliminating hydrogen embrittlement on high-strength steels, and corrosion resistance up to 1,000 hours in ASTM B117 salt spray testing.

Chousa monetizes through three streams: (1) surface treatment services performed at the Ciudadela facility on customer-supplied components, (2) sale of proprietary coating products and thread-locking technologies, and (3) a Global Licensing Program that transfers LAURENTCOAT® formulations, application know-how, and raw material supply chains to licensed partners worldwide. Documented enterprise references include YPF Luz (Parque Solar El Quemado, 305 MW) and Parque Solar Cauchari, where LAURENTCOAT®-protected fasteners are specified for 25-year service life in Argentina's largest solar installations.

Direct peers

• Coventya: Coventya is a specialty chemicals company focused on electroplating and surface finishing for fasteners, including zinc, zinc-nickel, and decorative/functional coatings. Direct competitor in the same product categories and customer base (fastener manufacturers, automotive, industrial).
• Dörken MKS Systems: Dörken MKS (part of the Ewald Dörken Group) produces DELTA-PROTEKT® and DELTA-TONE® zinc flake coatings, the most direct technical competitor to LAURENTCOAT® globally. Serves automotive, wind energy, and construction fastener manufacturers with virtually identical product positioning and performance specifications.
• Magni Group: Magni Group manufactures thin-film corrosion-resistant coatings, particularly for fasteners serving automotive, heavy truck, and wind energy markets. Direct peer in zinc flake technology with similar OEM specification-driven business model.
• NOF Metal Coatings (Zintek / Geomet): NOF Metal Coatings is the global market leader in zinc flake coating systems (Zintek and Geomet brands), directly competing with Chousa's LAURENTCOAT® in automotive, wind, and construction fastener applications. Highly comparable product chemistry, application method (dip-spin), and target customer base of OEM fastener manufacturers.

Broad incumbents

• MacDermid Enthone (Element Solutions): MacDermid Enthone is a large diversified surface finishing and coating chemicals supplier serving automotive, electronics, and industrial fastener markets. Overlaps with Chousa in zinc-nickel plating, trivalent passivations, and thread-locking pretreatment chemicals.
• Atotech (MKS Instruments): Atotech is a global leader in surface treatment chemicals, including zinc and zinc-nickel plating, passivations, and specialty coatings for fasteners. Much larger and broader portfolio than Chousa, but directly overlaps in electrolytic zinc-nickel and trivalent passivation offerings.
• PPG Industries: PPG is a global industrial coatings giant with protective and marine coatings lines relevant to Chousa's large-project applications (oil & gas, mining, infrastructure). A broad incumbent rather than a fastener-focused peer, but competes at the project level for corrosion protection specifications.
• Henkel (Bonderite): Henkel's BONDERITE brand covers surface treatment and coating technologies for metal finishing, including pre-treatments and conversion coatings comparable to Chousa's phosphate and passivation line. A broad incumbent competing in automotive and industrial OEM channels.

Regional players

• KC Jones Plating Company: KC Jones Plating is a North American metal finishing and zinc flake coating applicator serving automotive and industrial fastener manufacturers. Comparable in functional role (service applicator) but geographically focused on the US Midwest automotive cluster, not Latin America.

Emerging players

• SurTec (Holland Chemical International): SurTec develops surface treatment chemicals for metal finishing, including functional coatings and passivations used in industrial applications. Comparable product portfolio to Chousa's chemical surface treatment range, though more focused on pre-treatment and decorative finishing.
