"Weight reduction is required to improve the fuel efficiency of automobiles.
We have installed foam hot melt coating equipment.
By filling with nitrogen gas, it is possible to apply coating while foaming hot melt.
Compared to conventional butyl-based sealing materials, the weight can be reduced approximately 40% and workability can be improved.

[Hot butyl (current product)]
Material: butyl rubber base
Sealing: possible
Required crimping power: high
Assembly workability: Re-peel (re-work) is not possible
Weight (specific gravity): 1.1

↓ Weight reduction to improve fuel efficiency ↓

[Foam hot melt]
Material: hot melt + nitrogen gas
Sealing: possible
Required crimping power: low
Assembling workability: Re-peelable (reworkable)
Weight (specific gravity): 0.62 ->Succeeded in weight reduction approximately 40%

In addition, we posted our technology in the field of adhesive coating on our website!
