Product detailed description

WT250 ALU 600 ml – Manual Application Gun for Foil-Pack Sealants

The WT250 ALU manual application gun by DL Chemicals is designed for dispensing sealants from soft foil packs with a capacity of up to 600 ml.

Unlike conventional open-frame guns for rigid cartridges, it features an enclosed aluminium barrel that protects the foil pack during use. The 12:1 mechanical thrust ratio is designed for low- to medium-viscosity sealants.

Thanks to its 360° rotating frame, the gun is easier to handle when sealing construction joints and performing other installation work.

Main Benefits of the WT250 ALU Application Gun

• Designed for foil packs up to 600 ml

• 12:1 mechanical thrust ratio for standard applications

• Suitable for low- to medium-viscosity sealants

• Enclosed aluminium barrel to protect the foil pack

• 360° rotating frame for easier handling

Why Use a Gun Designed for Foil Packs?

Sealants are supplied in different packaging formats. In addition to rigid cartridges, soft foil packs are also used and require a suitable application tool.

The WT250 ALU has an enclosed aluminium construction designed for this packaging format. It helps protect the foil pack during dispensing and allows controlled sealant application.

12:1 Thrust Ratio – Which Materials Is It Suitable For?

According to the manufacturer, the 12:1 mechanical thrust ratio is designed for general use with low- to medium-viscosity sealants.

For very thick materials, compatibility with the gun should be checked. A higher thrust ratio or a different application tool may be more practical.

What Can the WT250 ALU Be Used For?

• Applying compatible sealants supplied in foil packs

• Sealing construction joints and gaps

• Sealing connections during installation and finishing work

• Dispensing compatible sealants in interior projects

• Working with suitable foil packs up to 600 ml

The gun is an application tool. Whether a particular sealant is suitable for indoor, outdoor or other conditions depends on the sealant itself.

How to Use the WT250 ALU Application Gun

1. Check that you are using a compatible foil pack with a capacity of up to 600 ml.

2. Prepare the foil pack according to the sealant manufacturer's instructions.

3. Open the application gun and insert the pack into the aluminium barrel.

4. Fit a suitable application nozzle and close the gun correctly.

5. Squeeze the trigger to apply the sealant evenly to the prepared substrate.

6. After use, release the pressure and clean the nozzle and tool according to the sealant manufacturer's instructions.

Always follow the sealant manufacturer's application and safety instructions.

WT250 ALU 600 ml vs Dual Power 310 ml

WT250 ALU 600 ml is designed for soft foil packs up to 600 ml and has a 12:1 mechanical thrust ratio.

Dual Power 310 ml is designed for standard rigid cartridges up to 310 ml. It features switchable 12:1 and 18:1 thrust ratios and an anti-drip mode.

The main factor when choosing an application gun is therefore the packaging type of the sealant.
