Alcohol-Cure (Alkoxy) RTV Silicone Storage — Neutral 1-Component Sealant Tank Selection

Storing RTV Silicone Alcohol Cure? Start Here

If you're dealing with alcohol-cure RTV silicone, you're handling a versatile sealant used in structural glazing, plumbing, and electronics. This type of silicone releases methanol or ethanol as it cures, making it a non-corrosive option compared to other sealants. It's compatible with a variety of materials, including copper, brass, and galvanized steel, and is ideal for environments sensitive to acidic byproducts.

Can you store it in a poly tank?

Yes, you can store uncured alcohol-cure RTV silicone in polyethylene tanks. Both HDPE and XLPE are suitable for this purpose, as they handle the moisture-sensitive paste and the methanol or ethanol vapors released during curing. Ensure your tank is equipped with proper venting to manage these vapors.

Mind the Vapors

The key issue with storing alcohol-cure RTV silicone is managing the methanol or ethanol vapors released during curing. Proper venting is crucial to prevent vapor buildup, which could exceed safety limits. Consider plumbing vents to local exhaust systems or using carbon-canister vapor capture.

The safety that actually matters

• Ensure tanks are properly vented to manage methanol or ethanol vapors.
• Use FKM gaskets for long-term durability with methanol exposure.
• Regularly check for leaks or vapor buildup to maintain a safe environment.

Common questions

What tank materials are best for storing RTV silicone?

HDPE or XLPE tanks with polypropylene fittings and FKM gaskets are recommended.

How should I manage the vapors?

Install proper venting systems to direct vapors to exhaust or capture systems.

Can RTV silicone be stored in stainless steel tanks?

Yes, 316L stainless steel tanks are ideal for finished-paste storage in production environments.
