•
- Push the applicator head onto the bottle, and fit the felt pad.
- Wet out the felt pan by inverting the applicator bottle and gently squeezing the sides.
- Wipe the pad over the substrate surface using minimal pressure to wet the surface.
- Immediately wipe off the activated/cleaned surface using a clean fibre free cloth, and dis-
card.
Notes: - If the substrate is very dirty, first wipe off the surface with a clean fibre free cloth and discard.
- Do not leave the caps off Betawipe containers. A milky colour indicates moisture absorption,
and the material should be discarded.
- Only decant a sufficient quantity of Betawipe for the job concerned, and never pour material
back into the container from the applicator bottle.
- Change the felt pad at regular intervals to reduce surface contamination.
3900 (A100B6008V)
Degreaser and cleaning agent used for the removal of contamination from the substrate sur
face. Supplied in 1 litre aluminium container with a BLACK coloured cap.
- Wipe on/wipe off type.
- When substrate is very dirty, first wipe off the surface with a clean fibre-free cloth and dis-
card.
- Dampen a fibre-free cloth with Betaclean 3900, and immediately replace the black cap.
- Thoroughly clean the substrate surface with Betaclean and discard the cloth.
- Wipe off the substrate with a clean fibre-free cloth and discard.
BETAWIPE 4000 (A082B6355V)
Description: Cleaning agent which acitvates the old adhesive layer to accept new adhesive. Supplied in
250 ml aluminium containers with a BLUE cap.
Application: - The residual adhesive bead should be cut with a scalpal to leave an even thickness of
approximately 1 to 2 mm.
- Dampen a fibre-free cloth with Betawipe 4000 and immediately replace the blue cap.
- Thoroughly clean the substrate surface with Betawipe and discard the cloth. Do not wipe off.
- Allow 2 - 3 minutes flash off time before applying adhesive.
5001 (A100B6009V)
Adhesion promotor used to maximise the performance of the bonding between the cleaned
and/or activated surface and the adhesive compound. Supplied in 250 ml aluminium con-
tainer with GREEN coloured cap.
- Two steel balls inside the container are provided to assist mixing of the contents when
shaken. Prior to decanting Betaprime 5001, shake the container for at least 60 seconds to
disperse the solid content of the material into suspension.
- Pour the primer into the applicator bottle and immediately replace the green cap.
- Wet out the felt pan by inverting the applicator bottle and gently squeezing the sides.
- Wipe the pad over the activated/cleaned substrate surface to apply a continuous film of
primer.
- Allow to dry for a minimum of 15 minutes before applying adhesive. If adhesive is not
applied with 72 hours, wipe on/wipe off with Betawipe VP 04604.
- The appearance of the primed areas should be deep black in colour with no streaks or voids.
To achieve this appearance, apply in smooth continuous uni-directional movement, not short
backward and forward movements. The latter technique results in inconsistent film build.
Rework any poor areas after 5 minutes (tack time), applying in the same direction.
- Replace the felt pad if moisture absorption results in hardening.
- Never return unused Betaprime back into the aluminium container.
BETAPRIME 5404 (A082B6337V)
Description: Adhesion promotor used to maximise the performance of the bonding between the cleaned
and/or activated surface and the adhesive compound. Supplied in 250 ml aluminium con-
tainer with RED coloured cap.
Application: - Two steel balls inside the container are provided to assist mixing of the contents when
shaken. Prior to decanting Betaprime 5001, shake the container for at least 60 seconds to
