Specialty Polyolefin
Adhesives
 The
wide use of polyethylene
and polypropylene plastics as well as their
copolymers and alloys has increased interest in adhesive bonding
of these materials. Polyolefins are very difficult to bond
on account of their non-polar, non-porous and chemically inert
surfaces. Their high degree of chemical inertness to solvents
generally limits the usefulness of solvent bonding as a viable
assembly technique. One successful approach to adhesive bonding
of these materials involved proper surface pretreatment prior to bonding.
The pretreatments which are widely accepted include chemical etching, flame
treatments, corona discharge and gas plasma. Recently, specially
formulated primers have been used as a pretreatment procedure.
A second approach is the use of specialty adhesives such as
hot melts (e.g. Master Bond MB514), high tack pressure sensitive adhesives
(e.g. Master Bond LTX164) and Master Bond's solvent based specialty adhesives
(e.g. Master Bond X17).
Where structural integrity is not of primary importance, and depending
on the size and geometry of the parts to be bonded, Master
Bond X17 may also be a viable primer option.
