Structural bonding in the body construction for automotive

In body-in-white, the spot welding process is increasingly being replaced or supplemented by structural bonding. The advantages here are optimized crash behavior and improved corrosion protection. As a rule, adhesives are applied to the raw part and spot-welded to each other through the adhesive seam. The adhesive then hardens in the KTL furnace.

BETAMATE™ 1-component epoxy resin adhesives

Specially developed for use in automotive shell construction to increase crash stability and stiffness. They adhere excellently to the oiled steel and aluminium grades used.

BETAMATE™ 2-component epoxy resin adhesives

For crash-resistant structural bonding of repair sheets and metals in general as well as fiber-reinforced plastics. Achieves approximately the strength of 1K epoxy resin adhesives.

L&L Core Splice Adhesives

Expanding adhesive mats used in composite sandwich structures. For bonding honeycomb joints and edge formation on GRP/CFRP pressed parts. Mats can be cut to size and expand thermally in ovens, presses or autoclaves. Low density.

L&L Heat activated sealants

L&L Heat activated sealants are applied as self-adhesive inflatable tapes into body cavities (A/B/C columns, roof frames etc.), expand these by heat activation, e.g. in the KTL process, and seal these completely against the penetration of moisture, air and dust.

L&L Room temperature curing sealant/adhesives

Elastic 1K sealants based on MS polymer and elastic 2K adhesives with various mechanical properties. Direct adhesion to a variety of materials without pre-treatment.

L&L structural adhesive films

Self-adhesive EP adhesive strips, activated by heat, typically used in body-in-white construction. Different expansion rates enable bridging of gaps, compensation of thermal expansion and galvanic separation of substrates. Reinforcement of flat components.
