Easy-Mix PE-PP
WEICON Easy-Mix PE-PP is a two-component
construction adhesive on the basis of methyl acrylate.
It is in particular suitable for structural, high-strength
bonding of Iow energy plastics like PE, PP and TPE.
A pre-treatment of the surfaces to be bonded is not
required.
In addition, WEICON Easy-Mix PE-PP can be used as
"universal adhesive" for plastics like:
• Rigid PVC (polyvinyl chloride)
• PA (polyamide)
• PC (polycarbonate)
• ABS (acrylonitrile-butadiene styrene)
• PMMA (polymethyl methacrylate)
• Fibre reinforced materials (GRP, CRP, fibre glass etc.)
and many others.
WEICON Easy-Mix PE-PP features the following
characteristics:
• No pre-treatment of the parts to be bonded
("integrated primer")
• Short pot life and processing time
• Fast development of strength
• High final strength
• Curing with residual elasticity
• Aging resistant
• Chemical resistant
• Controlled bonding gap of min. 0.15-0.20 mm
through special additives (glass beads)
• Pasty, stable

Thanks to the modern mixing and dosing system WEICON
Easy-Mix, the adhesive can be cleanly and accurately
automatically dosed, mixed and applied in only one
working operation.

Plastics like PE and PP are increasingly used in almost
all industrial areas nowadays due to their specific
properties, like plasticity, elasticity, breaking strength,
and temperature, thermoforming, and chemical
resistance.
Product advantages:
• ready for use
• dosing, mixing and application in just one working
operation
• tedious mixing by hand is no longer necessary, so
that no mixing and dosing mistakes are possible
• speedy in application, thus faster cycle times in series
production are possible
• economical in use, due to minimal material wastage
For the adhesion of these plastics, the surfaces have had
to be extensively pretreated until now, for example:
• Mechanically (grinding, sandblasting, etc.)
• Chemically (fluorination)
• Physically (flame treatment, corona, plasma)
With the new adhesive WEICON Easy-Mix PE-PP,
these pretreatments are no longer required. The "primer
integrated" into the adhesive activates the surfaces and
makes high-strength bonds possible.
WEICON Easy-Mix PE-PP can be used for individual
applications as well as for small-lot fabrication or
industrial series production, e.g. bonding and repair
of small appliances, signs and displays, loudspeaker
parts, battery housings, plastic tanks and many other
plastic parts.

WEICON Easy-Mix PE-PP
Difficulties in the adhesion of plastics arise from a low
surface tension (low-energy) and the resulting incomplete
wetting of the adhesive surface.

Processing:
The prerequisite for perfect adhesion are clean and dry surfaces (e.g.
cleaning and degreasing with Cleaner S or Plastic Cleaner). Smooth
surfaces can be roughened mechanically, for example with grinding
paper grain size P 120.
WEICON Easy-Mix PE-PP can only be processed with the WEICON
Dispenser Pistol with special piston (10:1) and the special mixing
nozzles for this system. It is absolutely essential that the mixing nozzle
is put on correctly (details hereof can be found in the instructions for
use attached to each packing unit).
Optimum processing is at room temperature (+20°C to +25°C / +68°F
to +77°F).
WEICON Easy-Mix PE-PP has a pot life and a processing time of
approx. 2-3 minutes. Immediately after the application of the adhesive,
the parts to be bonded should be joined, then positioned and fixed
for curing.
The integrated additives (glass beads) provide a minimum thickness of
the adhesive layer of 0.15 mm to 0.20 mm. This thickness is required
for the chemical reaction between the adhesive and the plastic to be
bonded.
Best strength values are achieved with adhesive layers of 0.20 mm
to 0.30 mm.
Physiological properties / health and safety at work
WEICON Easy-Mix PE-PP, when properly handled and completely
cured, is toxicologically essentially harmless. When using the adhesive,
the physical, safety technical, toxicological and ecological data and
regulations in our EC safety data sheets (www.weicon.de) must be
observed.
