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 24 hours, re-activate by applying a further coat of Betaprime 5404.
Notes: - 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.
VP 01706 A+B (A100B6070V)
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-
tainers of component A and component B.
- Thoroughly shake component A container to disperse solid material. Remove the lid from
the component A container and scrape any sediment from the botton of the container. Re-
place the container lid and thoroughly shake again to disperse the solid content.
- Pour the required amount of component A into a clean container, and add the same volume
of component B. Replace lids immediately. Thoroughly mix the two components for 45
seconds minimum.
- Leave the mixed components to stand for 30 MINUTES. (Discard if unused after 8 hours)
- Pour the primer into the applicator bottle and wet out the felt pan by inverting the bottle and
gently squeezing the sides.
- Wipe the pad over the cleaned substrate surface to apply a continuous THIN film of primer:
A thin, almost transparent film is all that is required. No attempt should be made to attain a
completely opaque covering.
- Allow to dry for a minimum of 4 HOURS, before applying adhesive.
- To achieve a continuous thin film of VP 01706, apply in a smooth continuous uni-directional
movement, not short backward and forward movements. The latter technique results in in
consistent film build.
- Replace the felt pad if moisture absorption results in hardening.
- Never return unused Betaprime back into the aluminium container.
BETAPRIME
Description:
Application:
Notes:
BETASEAL 1701 (A082B6281F)
Description: One component moisture curing adhesive, providing high strength, permanently elastic bonds
between various substrates. Supplied in 300 ml aluminium cartridge.
Application: - Remove the cartridge end ensuring there is no damage to the reinforcing sleeve.
- Pierce the neck of the cartridge and screw on the applicator nozzle. Cut the nozzle end to the
required diameter and shape.
- Fit the cartridge into an air assisted gun, and extrude a smooth, even and continuous bead
of Betaseal to the previously prepared substrate.
- Assemble the joint within 5 MINUTES.
Notes: - If the adhesive has to be touched or manipulated for any reason, use only wetted fingers.
BETAMATE E2400 (A082B8415V)
Description: Two component chemically curing adhesive, providing high strength, permanently elastic bonds
between various substrates. Supplied in 220 and 450 ml aluminium cartridges.
Application: - An electrically driven Betagun Mk 11 is required to mix and extrude Betamate E2400. Refer
to the operating instructions supplied with the gun.
- Extrude a smooth, even and continuous bead of Betamate to the previously prepared substrate.
- Assemble the joint within 5 MINUTES.
Notes: - If the adhesive has to be touched or manipulated for any reason, use only wetted fingers.
