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.
