Approche de solution

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)
Hydrochloric Acid
CAS 7647-01-0
Acides et Sels
Carbon-steel pickling & descaling
1789 (HYDROCHLORIC ACID, SOLUTION) · Class
Dissolves iron-oxide mill scale and rust to soluble ferrous chloride - the workhorse strong-acid pickle for carbon steel
Point de fusion:-115 °C (Melting point is -25 °C for a 39.17% w…   Point d'ébullition:51 °C at 760 mmHg   Densité:1.05 at 15 °C for 10.17% weight/weight solution

Phosphoric acid
CAS 7664-38-2
Acides et Sels
Derusting & iron-phosphate conversion
1805 (Phosphoric acid, solution) · Class
Strips rust while leaving a thin protective iron-phosphate film, so it both descales and passivates ahead of painting
Point de fusion:42 °C   Point d'ébullition:> 130 °C at 760 mmHg   Densité:1.892 at 25 °C

Sulfamic Acid
CAS 5329-14-6
Acides et Sels
Nettoyage / Dégraissage
2967 (SULFAMIC ACID) · Class
Sulfamic acid (H3NO3S) is a solid INORGANIC acid - not organic - that descales carbonate and oxide scale with low fuming and without the chloride attack of HCl, making it safer for mixed-metal parts
Point de fusion:Melting point equals 205 °C   Point d'ébullition:DECOMP @ BOILING POINT   Densité:2.15

Citric Acid (Anhydrous, FCC Food Grade)
CAS 77-92-9
Acides et Sels
Chélation / Séquestration
Mild organic acid that chelates iron as it dissolves rust, giving controlled passivation pickling for stainless and precision parts
Point de fusion:153 °C (anhydrous)   Point d'ébullition:Decomposes   Densité:1.54 at 20 °C
