PUR Hot-Melt Reactive (Moisture-Curing Polyurethane Hot-Melt) Tank Selection

Storing PUR Hot Melt Reactive? Start Here

If you're working with PUR Hot Melt Reactive adhesives, you know they're essential in woodworking, furniture, and assembly operations. These adhesives are known for their high strength and resistance to heat and moisture. However, storing and handling them correctly is crucial to maintain their performance.

Can you store it in a poly tank?

No, polyethylene tanks are not suitable for storing PUR Hot Melt Reactive adhesives at the required high temperatures. Instead, stainless steel tanks are recommended for their chemical inertness and ability to handle the necessary heat.

Watch out for moisture exposure

PUR Hot Melt adhesives react with moisture, which can cause skinning and viscosity changes in the melt tank. To prevent this, a nitrogen blanket is essential to protect the adhesive from atmospheric moisture during storage and use.

The safety that actually matters

• Use stainless steel tanks for high-temperature storage.
• Implement a nitrogen blanket to prevent moisture exposure.
• Regularly monitor and maintain tank conditions to ensure stability.

Common questions

Can I store PUR Hot Melt in a plastic tank?

No, plastic tanks cannot withstand the high temperatures required for storing PUR Hot Melt.

Why is a nitrogen blanket necessary?

A nitrogen blanket prevents moisture from reacting with the adhesive, which can affect its performance.

What materials are suitable for gaskets?

Viton (FKM) is recommended for gaskets in high-temperature applications with PUR Hot Melt.
