Section BQ 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 5404, 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 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. BETAPRIME VP 01706 A+B (A100B6070V) 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 tainers of component A and component B. Application: - 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 pnmer 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. Notes: - 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 incon- sistent film build.
- Replace the felt pad if moisture absorption results in hardening.
- Never return unused Betaprime back into the aluminium container. 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. |
