Situation:

A truck body manufacturer in the U.S. was dissatisfied with the performance of a competitive adhesive to bond door panels to frames in an attempt to replace a skip welding process.

Substrates: Aluminium – Alloy

Challenges:

The client was facing the following challenges with the existing solution:

• Skip welding damages the surface of the door panel and leaves an open seam in the truck body
• Competitive adhesive could not pass impact or field testing resulting in warranty claim increases
• Overall adhesive process and material cost must be lower than current welding expenses

Product used:

LOCTITE H8000, BONDERITE M-NT 5700 Wipes

Solution:

The client required an adhesive that bonds well to aluminum and passes impact testing. Henkel recommended LOCTITE H8000 as a solution. LOCTITE H8000 seals the door panels to prevent corrosion and improves the truck body aesthetic appearance.

Results:

• LOCTITE H8000 resolves the previous skip weld surface blemishes highlighted by the paint coating
• LOCTITE H8000 bonding method eliminates panel warpage and seals seams to prevent corrosion
• LOCTITE truck panel bonding processes lower previous assembly time, labor costs and warranty claims

Benefits:

• Elimination of panel warpage
• Prevention of corrosion
• Decrease in assembly time
• Decrease in labor costs
• Decrease in warranty claims
