CSNRI
Utilizing global partner products — CSNRI and Loctite are both part of Henkel (Critica Infrastructure acquired in November 2023), and are not manufactured in-house by HIGHCOATIC.
A global partner supplying composite wrapping products for the trenchless restoration of pipes suffering from corrosion and wall loss, and online emergency repair products for sealing active, pressurized leaks during operation. CSNRI and Loctite are both brands under Henkel.
About CSNRI
CSNRI (Critica Infrastructure) is a specialized brand for engineered composite repair solutions that restore corroded, thinned, or damaged industrial pipelines and structures without cutting or replacement. It widely supplies composite wrap methods that restore pipe strength and prevent external corrosion using resin-impregnated fiberglass and carbon fiber composites, as well as online emergency leak repair products that urgently seal leaking pressurized pipelines in operation without shutdown.
CSNRI products comply with international pipeline repair standards such as ISO 24817 (ISO/TS 24817), ASME PCC-2 Article 401, US CFR 192/195, CSA Z662, and ASME B31.
Relationship with HIGHCOATIC
HIGHCOATIC is a global partner that utilizes CSNRI products in its pipeline maintenance (composite wrapping and online emergency leak repair) solutions. The products introduced below are partner products manufactured by CSNRI, not products manufactured by HIGHCOATIC itself.
Clarifying Corporate Relationships
In November 2023, Henkel acquired Critica Infrastructure, CSNRI's parent company, making both CSNRI and Loctite brands under Henkel. The common misconception that 'Loctite acquired CSNRI' is inaccurate; the accurate statement is that 'both brands are under Henkel'.
