Do not select an IBC only from the chemical name. Confirm the exact product specification, operating conditions, current approval and site risk assessment.

Before choosing an IBC for Fluorosilicic acid

The VARIBOX chemical overview lists fluorosilicic acid but does not state a universal concentration range here. Confirm the exact solution specification before use. Before choosing a final IBC configuration, confirm:

• Exact chemical name, formulation and concentration
• Minimum and maximum filling, storage and transport temperatures
• Any additives, impurities or mixtures that can affect compatibility
• Viton (FKM) seal compatibility for the actual operating conditions
• The specified vacuum vent and any application-specific venting requirements
• Filling and emptying process, valves, couplings and connection requirements
• Site containment, risk assessment and local storage requirements
• Applicable transport documentation and the current chemical approval
• Inspection, cleaning, reuse and return-cycle requirements

See the EPDM or Viton FAQ, review the Chemicals in the VARIBOX overview, or contact VARIBOX for an application-specific check.
