Contact SupplierDubond Ultraflex is two-component solvent and water free adhesives which are flexible and waterproof. They are made up of a polyurethane base (component A) and a special hardener (component B). Dubond Ultrflex is an improved (2) reaction resin adhesive (R) and slip resistant (T) classfied as R2T
Features & Benefits
High deformability.
In the case of Ultraex, highly thixotropic: it can be applied vertically without slump and without le tting even heavy or large tiles slip
Area of Application
Preparation of Substrate
The substrate must be cured, mechanically strong, free o f loose particles, grease, oil, paint , wax and be sufficiently dry. Cement substrate must not be subject to shrinkage after the installation of the tiles. During spring and summer renders must be cured for at least one week for every centimeter of thickness and cementitious screeds must be cured for at least 28days , unless they have been made with DUBOND special binders for screeds such as DUCEM, DU GO SL. Where this not observed, the adhesion of Ultraflex to the substrate will be greatly compromised. Rust on iron surfaces must be removed by sandblasting. It is recommended to reinforce gypsum, gypsum board and anhydrite substrates with a coat of Primer.
Application
Tiles must be absolutely dry. Apply firm pressure to the ?les to ensure good contact and covering of the back. If the layer of fr esh Ultraflex is also to act as a waterproofing membrane, make sure that any ribs and lugs do not go through the layer. If Ultraflex is used for installing on particularly deformable substrates, all coverings larger than 5x5 cm must be installed with wide joints. The open time of Ultrafex under normal temperature an d moisture conditions is approximately 50 minutes. Any adjustment must be carried out within 90 minutes of installation.
Precautions & Limitation
Shelf life & Storage
Ultraex are stable for at least 24 months when stored in sealed drums. Component B (hardener) must be stored in warm place to avoid crystallization during cold weather (at least at +10°C). Should crystallization occur, re -dissolve by warming before use. Stir the product before use.
