Metalworking — Process Challenge

Korrosionsschutzmittel für bearbeitete Werkstücke

Eisen- und Nichteisenwerkstücke rosten (Flashrost) oder anlaufen während der Bearbeitung und der Zwischenlagerung; die Formulierung erfordert Korrosionsschutzmittel für Eisenmetalle und Gelbmetalle.

Lösungsansatz

RawSource supplies the base chemicals that go into these programs. We can help with product selection, grade matching, and sourcing from multiple origins for supply security.

Typical Selection Workflow
1
Process & Requirement Definition
Map the unit operation and define the functional, purity, and regulatory requirements the chemical input must meet.
2
Chemistry & Grade Selection
Match the solvent, intermediate, acid or base, catalyst, or specialty additive to the process and downstream compatibility.
3
Trial & Specification
Validate performance at bench or pilot scale, and set the grade, treat rate, and packaging to match throughput and handling.
4
Quality & Supply Assurance
Lock the spec with a CoA and secure multi-origin sourcing for supply resilience and consistent lot quality.
Recommended Chemistries (5)
Natriummolybdat
CAS 7631-95-0

Benzotriazole (BTA)
CAS 95-14-7
Spezialadditive
Copper and yellow metal corrosion inhibitor
Chemisorbs onto copper and brass to build a Cu-BTA monolayer that blocks oxygen access, stopping tarnish on non-ferrous machined components
Schmelzpunkt:98–100 °C   Siedepunkt:204 °C at 15 mmHg   Dichte:1.36 g/cu cm at 20 °C

Tolyltriazole (TTA / Methylbenzotriazole)
CAS 29385-43-1
Spezialadditive
Konservierung
Methyl (tolyl) triazole gives the same copper-passivating film as BTA with better solubility and persistence in alkaline coolants

2-Mercaptobenzothiazole (MBT)
CAS 149-30-4
Spezialadditive
Korrosionsschutz
2811 (2-MERCAPTOBENZOTHIAZOLE) · Class
Thiazole that chemisorbs through its sulfur onto copper and brass to form a protective film; primarily a yellow-metal inhibitor for soluble-oil systems, paired with nitrite/molybdate when steel must also be protected
Schmelzpunkt:177–181 °C   Siedepunkt:Decomposes   Dichte:1.42 at 20 °C

Alle Details
Sodium Nitrite (FCC), Food Grade
CAS 7632-00-0
Spezialadditive
Korrosionsinhibitor für Eisenmetalle
1500 (SODIUM NITRITE) · Class
Strong anodic passivator for steel - oxidizes the metal surface to a protective gamma-Fe2O3 film, the traditional ferrous MWF inhibitor
Schmelzpunkt:271 °C   Siedepunkt:Decomposes at 320 °C   Dichte:2.17 at 20 °C
