Capstone C6 Fluorosurfactant Storage — Chemours Tank Selection

Storing Capstone C6 Fluorosurfactant? Start Here

Capstone C6 fluorosurfactants are a group of short-chain chemicals used primarily in coatings and industrial processes. They are designed to reduce surface tension, making them effective in applications like paints and metal cleaning. If you're considering storing these surfactants, it's important to understand how they interact with different materials and the regulatory landscape surrounding their use.

Can you store it in a poly tank?

Yes, you can store Capstone C6 fluorosurfactant solutions in polyethylene tanks. High-density polyethylene (HDPE) or cross-linked polyethylene (XLPE) tanks are standard choices. Just ensure there is no plasticizer leaching with extended contact.

Watch Out for Elastomer Penetration

The key issue with storing Capstone C6 fluorosurfactants is their potential to penetrate certain elastomers. While the surfactants themselves don't aggressively attack tank walls, they can penetrate and degrade seals made from materials like Buna-N or natural rubber. Using FKM (Viton) gaskets is recommended for better compatibility.

The safety that actually matters

• Ensure tanks are made from compatible materials like HDPE or XLPE.
• Use FKM gaskets to prevent elastomer penetration.
• Monitor for any signs of material degradation over time.
• Stay informed about regulatory changes affecting PFAS chemicals.

Common questions

Can I use a metal tank for storage?

Yes, 316L stainless steel is compatible, but avoid carbon steel without protective measures.

What fittings should I use?

Polypropylene fittings are standard for these tanks.

What about environmental regulations?

Be aware of ongoing regulatory changes, especially concerning PFAS emissions and contamination limits.
