WEB SPRAY AEROSOL

Description

Description & Uses
AlphaChem Web Spray aerosol is a fast drying, high tack spray adhesive, suitable
for permanently bonding a wide variety of substrates including wood, metals,
rubber, most plastics, cardboard, polythene and concrete, as well as decorative
laminates. It provides a permanent bond with good temperature resistance.
Directions
 Use in a well ventilated area.
 Ensure all surfaces are clean, sound, dry and free from dust, grease or other
contaminants.
 Substrates should be conditioned before assembly, this is particularly
important with laminates. Condition for 48 hours at 20°C with a relative
humidity of 45‐55% ‐ air should be able to circulate freely around all
components.
 Hold the aerosol at approximately 70° to the surface and apply a generous
and even coat of adhesive, ensuring 80‐100% coverage, moving the aerosol
parallel to the surface, pay particular attention to the edges.
 On porous surfaces a second coat might be necessary – always apply to
laminate first and spray one surface horizontally and the other vertically.
 When the adhesive is dry to the touch, and does not transfer, it is ready for
bonding.
 Bring the two surfaces together and apply a uniform pressure, starting in
the middle and working out, pay particular attention to the edges.
 Drying time is 2 minutes under normal conditions, but this will vary with
differing temperatures and humidity’s. High humidity & low temperatures
will slow drying time, and it the temperature gets very low it can produce
bloom. Full cure takes 24 hours.
 Avoid over spraying and pooling of the adhesive as this will increase the
drying time and may cause adhesive to show through the laminate. If the
surfaces are bonded without allowing the adhesive to become dry, solvent
entrapment will occur and this will lead to bond failure.
 It is the user’s responsibility to dispose of all packaging correctly.

Cleaning
Web Spray Aerosol can be removed with most solvent cleaners.

Storage
Store between 5 and 25 in clean dry shaded conditions in original unopened containers. Do not
allow the product to freeze.
Shelf Life
12 months when stored as directed.
Limitations
 Always test a small sample of the materials first to ensure the suitability of the product for the
application. For instance, some vinyl’s contain large amounts of plasticiser which, over time, can
migrate and soften the bond. When in doubt, test first.
 Do not use on flexible PVC or expanded polystyrene.
 It is the user’s responsibility to ensure suitability for use. It is advisable to read the SDS prior to
use.
 Read the label carefully for essential health and safety information prior to use.
