Situation:

A manufacturer of water-tight telescopic covers was incurring increased warranty repair costs due to leaks from between the spot welds of the stepped steel panels of the cover.

Substrates: Mild Steel

Challenge:

Currently the manufacturer was using local sealants with which they faced the following challenges:

• Competitive sealants fail to provide a complete seal between welds on telescoping panels
• Poor adhesion leads to costly production rework and warranty repairs at their customers
• Rework expenses of travel, labor, and additional materials drive up manufacturing costs

Solution:

To provide water tight sealing, Henkel solutions expert recommended Teroson MS 930 modified silate sealant. Post cleaning the panels, Teroson MS 930 was pneumatically dispensed into the gaps between the spot welds to seal the section.

Results:

Sealing with Teroson MS 930:

• Provided 100% sealing
• Eliminated rework in manufacturing and warranty repairs at the end user
• Reduced cost per application
