ETONIS® 5150 P

• Concrete Protection
• Concrete Repair

ETONIS® 5150 P is particularly suitable for modifying concrete, especially for shotcrete applications in underground construction, tunneling and mining.

Processing

ETONIS® 5150 P is suitable for both wet and dry spraying. It can be added either to the ready-mixed concrete or to the gaging water. ETONIS® 5150 P allows low water/cement ratios to be used. The modified concrete can be efficiently processed, with low dust and no separation. It can be adjusted to technical requirements on-site. When calculating the water/cement ratio, the water content of ETONIS® 5150 P should be added to the water content of the concrete.

Consumption

Using ETONIS® 5150 P cuts system costs by reducing material consumption (e.g. rebound), time and labor. Overall, energy costs are reduced.

• ETONIS® 5150 P optimizes the adhesion and cohesion of the entire system.
• It significantly reduces spray rebound while greatly improving adhesion to all substrates, particularly wet surfaces.
• Concrete modified with ETONIS® 5150 P seals against pressing water and optimizes flow and compaction properties, while improving ultimate strength and CO₂ resistance.

Non-returnable PE drums of 150 kg capacity (standard dispatch quantity: only fully-loaded pallets à 750 kg), non-returnable containers of 1 t capacity and road tankers.

• When the dispersion is stored in tanks, proper storage conditions must be maintained. The product has a shelf life of 6 months starting from the date of receipt if stored in the original, unopened containers at temperatures between 5 and 30 °C.
•  Iron or galvanized iron containers and equipment are not recommended. Corrosion could result in discoloration of the dispersion or blends made from it in further processing.
• We therefore recommend the use of containers and equipment made of ceramic, rubberized or enameled materials, appropriately finished stainless steel, or plastic (rigid PVC, polyethylene or polyester resin).
• As polymer dispersions may tend to superficial film formation, skins or lumps may be formed during storage or transportation. A filtration process is thus recommended prior to utilization of the product.

Preservation for Transport, Storage and further Processing

• The product is adequately preserved during transportation and storage if kept in the original, unopened containers. However, if it is transferred to storage tanks, the dispersion should be protected against microbial attack by adding a suitable preservative package.
• Measures should also be taken to ensure cleanliness of the tanks and pipes. In unstirred tanks, a layer of preservative-containing water should be sprayed onto the surface of the dispersion to prevent the formation of unwanted skin and possible attack by microorganisms.
• The thickness of this water layer should be < 5 mm for low viscosity dispersions and up to 10–20 mm for high viscosity products. Proper procedures – periodic tank cleaning and sanitization – must be set up in order to prevent microbial attack.
• Measures should be taken to ensure that only clean air enters the tank when the dispersion is removed. Finished products manufactured from polymer dispersions usually also require preservation.
• The type and scope of preservation will depend on the raw materials used and the anticipated sources of contamination. The compatibility with other components and the efficacy of the preservative should always be tested in the respective formulation.
