Using the product:
1.Surface preparation:
Rubber: The bonding
surfaces must be completely clean, dry, and free from grease and oil. Buff
surface by using abrasive disc (grit 16-24) or similar, remove all shiny areas.
Completely remove all dust particles. In case of rubber with CN backing buffing
is not necessary, but clean CN backing in any case using fast evaporating
solvent.
Metal: The metal
surfaces must be totally clean, dry, and free from grease and oil. Sand- or
shotblast the metal surface to a roughness of Rz 90 - 140, remove dust and wash
with fast evaporating solvent (ELASTOSAL Lösit H6). For maximum adhesion use
imperatively ELASTOSAL Metallprimer, apply one thin coat on pretreated metal
surface and let dry completely (appr. 30 min).
2.Mixing the components: Mixing ratio: Adhesive
ELASTOSAL H6 : Hardener ELASTOSAL Härter RE / RFE = 100:7 by volume. Mix
thoroughly (2-3 min). Max. handling time of mixed product is up to 2 hours in
covered/closed buckets.
3.Applying the product: 2 coats are necessary. Apply the first thin and even
coat to both bonding surfaces using a paint roller or brush, and allow to dry
completely (min. 30 min). Apply second thin and even coat on both surfaces, and
allow to dry until slightly tacky (appr. 10 - 20 min), check with back of
finger nail. If too dry by false timing, apply third coat.
4.Joining: Join bonding surfaces together by applying strong and
short contact pressure (eg.using hammer, manual or pneumatic, with rubber head,
rollers etc.). Adhesion surfaces must have 100% contact with each other. Most favourable
bonding conditions are at 15-25°C and at 30-65% relative humidity of air.
Caution: Compensate for extreme conditions such as cold weather, spells, rain etc. through precautionary measures i.e. additional roofing and warm air supply etc.
