Flex+bond®
elastically
strong adhesion
WEICON Flex+bond is strong, permanently elastic, temperature
resistant from -40°C to +90°C (-40°F to +194°F), weather resistant,
resistant to UV rays, overpaintable (wet in wet), sandable, and resistant
to ageing and salt water. It is free of silicone, isocyanate, halogens and
solvents. WEICON Flex+bond has an ISEGA certifi cate and can be
used as an adhesive in foodstuff technology.
WEICON Flex+bond can be used to bond nearly all materials to
themselves and among each other such as metal, wood, plastic, glass,
and ceramics.

Pretreatment of the surface
The surfaces must be clean and grease-free. Many surface
contaminants, e.g. oil, dust and dirt, can be removed with WEICON
Surface Cleaner. For heavily soiled metal surfaces, we recommend
WEICON Cleaner Spray S; WEICON Sealant and Adhesive Remover
is suitable for removing old paint or adhesive residues.
Most materials can be bonded well to themselves and among each
other. For certain materials or extreme requirements, we recommend
the use of an adhesion agent (primer). Detailed information on this
subject is contained in the Primer selection table. A mechanical surface
pretreatment, e.g. sanding or
sand-blasting, can considerably improve the adhesion.
Processing
Processing tube
Squeeze out by hand, close tube again immediately after use, opened
tubes should be used up as quickly as possible.
Processing press pack
Remove original closure. Regulate discharge by smooth turning of the
cap from min. to max. Press the lever and process the medium. After
having turned the cap into the “min.” position the valve closes
automatically and the product flow is stopped.
Joining the parts to be bonded
To ensure optimum wetting, the parts must be joined before the first
skin has been formed on the adhesive (skin-over time).
Storage
When unopened and stored in a normal climate (+23°C and 50 % rel.
humidity), WEICON elastic one-component adhesives and sealants
have a shelf life of 12 months.
