Polyurethane Shelf Life Extender | Dry Gas Blanket | Moisture Protection Additive for Epoxy or Resins

Polyurethane Shelf Life Extender Dry Gas Blanket. Moisture is the number one cause of premature failure in opened polyurethane products. Even brief exposure to humid air can initiate curing reactions inside the container, resulting in hardened material, increased viscosity, or complete product loss.This polyurethane shelf life extender creates a protective layer that helps minimize moisture exposure after each use. Simply apply the recommended amount before resealing the container to help preserve the remaining material until your next application.Ideal for manufacturers, composite fabricators, flooring contractors, mold makers, woodworkers, and industrial users who regularly work with moisture-sensitive polyurethane systems.

How It Works

After dispensing your polyurethane material, spray a short burst into the headspace of the container before sealing the lid.

The protective gas displaces humid air inside the container, reducing moisture contact with the remaining material and helping preserve its original properties.

For best results:

• Wipe excess material from the container rim.
• Spray into the container immediately before closing.
• Reseal the lid tightly.
• Store in a cool, dry location away from direct sunlight.

Polyurethane Shelf Life Extender Dry Gas Blanket – Why Moisture Protection Matters

Polyurethane resins and isocyanates react quickly with atmospheric moisture. Once the curing process begins inside the container, product performance can be permanently affected.

Using a shelf life extender helps:

• Reduce product waste
• Maintain consistent performance
• Improve storage stability
• Protect expensive polyurethane materials
• Maximize the usable life of opened containers

Frequently Asked Questions

Can this be used with all polyurethane products?

It is recommended for most moisture-sensitive polyurethane resins, isocyanates, adhesives, coatings, elastomers, and casting systems.

Does it affect the chemistry of the resin?

No. The product only protects the container headspace from moisture and does not become part of the polyurethane formulation when used as directed.

How often should I use it?

Use it every time the container is opened before resealing for maximum protection.
