Reactive adhesives

Everad proposes a wide range of one- and two-component polyurethane- and silane-based reactive adhesives as well as others based on new raw materials developed by the chemical industry.

1-C adhesives harden in the presence of humidity in the material or in the air whereas, in 2-C adhesives, the two components react with each other. An increase in temperature can accelerate setting.

REACTIVE ADHESIVES HAVE A WIDE VARIETY OF APPLICATIONS:

• Sandwich panels and panels for partitions, ceilings and insulation
• Panels for refrigerating elements and metallic containers
• Panels for door and gate construction, tunnel doors
• Special doors (protection against radiation, fire, noise)
• Front panels
• Panels for the transport industry (HGV bodies and floors, wagon doors and ceilings)
• Wooden structures, staircase construction
• Casting resins for electrical components, industrial filters
• Sundry mounting jobs
• Bonding of soft foam (sponge manufacturing or temperature- or humidity-resistant complexes)

Mechanical properties (strength and elongation)
