EP
438/12 DV (XP)
Semi rigid/flexible adhesive, high chemical
resistance
DESCRIPTION
EP- 438/12 is a two component, semi rigid epoxy glue
displaying excellent adhesion
to metals, ceramics and sorts of plastics. EP
438/12 has high thermal shock resistance over a
range of temperatures and its flexibility avoids any
deformation between the glued articles. EP 438/12
perform excellent chemical resistance. The adhesive
can be cured with several curing agents in order to
achieve the desired properties.
