Silane Adhesion Promoter (Organofunctional Alkoxysilane Coupling Agent) Tank Selection

Storing Silane Adhesion Promoter? Start Here

If you're working with silane adhesion promoters, you're likely in the adhesive, sealant, or rubber compounding industry. These chemicals are crucial for bonding and are typically stored as either a neat liquid or a dilute solution. Understanding how to store them properly is key to maintaining their effectiveness and ensuring safety.

Can you store it in a poly tank?

Yes, but with conditions. For neat liquid silane, HDPE or XLPE tanks are acceptable for brief contact. However, for long-term storage, stainless steel is preferred. For dilute pre-hydrolyzed solutions, poly tanks are standard and effective.

Key Issue: Moisture Sensitivity

Neat liquid silanes are highly moisture-reactive. They can polymerize and form gels if exposed to moisture, so a dry atmosphere with a desiccant breather or nitrogen blanket is essential for long-term storage.

The safety that actually matters

• Ensure tanks are moisture-controlled to prevent unwanted reactions.
• Use appropriate gaskets: Viton for premium applications, EPDM for standard use.
• Store dilute solutions in day tanks to match their short pot-life.

Common questions

Can I store neat silane in carbon steel tanks?

No, it's not recommended due to potential corrosion and contamination.

What is the best material for gaskets?

Viton is preferred for its chemical resistance, especially in premium applications.

How long can I store the dilute solution?

It should be used within 30-90 minutes at the make-down station.
