Bonding Materials, Building Lighter Structures

Adhesives join dissimilar materials into a single structure, spreading loads evenly across the entire bonded area for greater stability.
Since no drilling is needed, components stay intact and lightweight designs become possible.
The adhesive layer also absorbs shock and vibration, reducing noise and ensuring more consistent product performance.
With core technologies in polyurethane, epoxy and acrylic adhesives, KCC offers structural adhesives as well as potting materials that
protect electronic components, motors, batteries and more. From automotive, industrial machinery and rail to aerospace and defense,
KCC delivers the right bonding solution for every industry.

For Vehicles

Automotive Adhesives

Automotive adhesives bond dissimilar materials in car bodies and
components. Working alongside welding and mechanical fasteners,
they help make vehicles lighter and more durable.
Automotive potting materials protect vehicle electronics and extend
their service life by shielding them from vibration, shock, heat,
moisture and other external stresses, improving overall product
reliability.
