Page 3 of 23 – European Technical Approval Saba Sealer MB(T) ETA-07/0124 – 30 October 2012II SPECIFIC CONDITIONS OF THE EUROPEAN TECHNICAL APPROVAL1 Definition of productThe Saba Sealer MB(T) joint sealing system, to be put in horizontal and vertical joints, is made of:1. Primer(s), see section below,2. Backfill material, not water absorbing and compatible with the joint sealing compound, “SabaBackfoam” or “Saba Rolyfoam PU”,3. Self-leveling joint sealing compound “Saba Sealer MB” (for horizontal application) or thethixotropic sealing compound “Saba Sealer MBT” (for mainly vertical application)”.Both sealer qualities are available in two shades: black and grey.The products will be designated in this document as Sealer MB, Sealer MBT and Sealer MB(T), thelatter when both types are included.The following primers are especially given by the manufacturer of the joint sealing system for therespective contact materials:1. “Saba primer 9102” for sealing constructions made of coated (only with a zinc rich primer) anduncoated metal, polymer materials such as hard PVC and polymer concrete.2. “Saba primer H17” for sealing constructions made of concrete (pre-cast or in situ) and for partsmade of semi-rigid pavements as well as the next contact materials:- Repair mortar “Betopox 012 WHG” (Epoxy based PC-mortar);- “StoCrete TG 203” (PCC)..3. "Saba primer 9911" for sealing constructions made of asphalt.The primers have to be applied to the joint sidewalls before the joint sealing compound is applied.The approved joint geometry (defined ratio of thickness and width) is presented in Annex 1. Thejoint sealing compound is suitable to be directly applied on already hardened, dry and clean SealerMB(T) joints. The joint sealing compound is applied in a plastic state and reacts to form a sealantwith predominantly elastic properties.
