|Category WINWET:||3. Repair & construction admixtures|
Admixture self-polymerizing homo-polymeric water soluble acrylic resin that withstands the constant contact with water and is designed to achieve hydraulic cement for use either as a cast self-leveling cement mortar or as repair cement with high waterproofness and flexibility without cracking.
|Materials together with which it is applied:||Cement, fine white sand, sea sand, water|
It contains no carcinogenic solvents, is water based. For more details, please read the Safety Data Sheet of the product.
|2. Data on the operation of the product|
|Which problems are solved by the product and in which ways:||
The problem of construction of hydraulic concrete in the form of fluid cast self-leveling cement mortar or repairing cement blocks with high waterproofness, elasticity and mechanical resistances, which will not crack as it dries remained until the summer of 2004 unsolved. Then it was released in the market, after a long investigation, the totally innovative product Betoplex, to substitute other resins which have had very reduced resistance to alkalinity and the expansions and contractions of the concrete, and a small to minimal weather resistance.
|Operating principle and way of action:||
The resin, as polymerized (“laminated”) due to contact with air, is creating a waterproof elastic mass which attaches great consistency and adhesiveness in mud and reduces the creation of pores during its drying. The result is a waterproof construction with high mechanical resistance, cohesion, elasticity and high waterproofness.
1. As a self-leveling cement mortar admixture (with water) for horizontal surfaces it offers to mud waterproofness, adhesiveness, elasticity, cohesion and resistance to expansions and contractions and vibrations and microseismic or other causes and prevents cracking of the cement mortar drying and after that detachment.
|Advantages over other methods:||
Compared with other additives in the market it has the following advantages:
|Comparison with other materials of Winwet family:||
Betoplex is of higher elasticity than the admixture Betostal SLN, which is used in other applications where resistance to mechanical stresses due to load and shocks is desired rather than high elasticity (e.g. mud to masonry construction).
|Experiment control of the efficacy of the product:||Text under construction.|

|3. Application of the product|
|Necessary equipment for the application:||
For the application of the resin you should have at your disposal what is indicated in the Winwet Application Equipment List.
|Protection of adjacent surfaces:||
Because when it is dried on marble, tiles, metals, etc. surfaces, it is hardly cleaned protect such surfaces with nylon or newspapers.
None. Pour the product in barrels, once you shed the cement, water and the other materials.
|Weather conditions during the application:||
On cloudy or sunny weather, cold or heat the end result will be exactly the same. The sun and the heat just accelerate the polymerization and waterproofing. If there is a forecast for rain by the National Meteorological Service, the application should be deferred.
|Lower polymerization temperature:||
3οC. If the temperature falls below 3οC before the polymerization is complete, the water begins to freeze and the same happens to the special penetrators containing the resin, thus losing its coherence and waterproofness. Therefore, you should avoid the application of the resin when it is very cold.
Although cement needs several days to dry thoroughly, the resin which is an admixture in it is fully waterproofed when polymerized, so it dries up.
|Completion time of polymerization:||
4 days or less. During the hot and dry days of summer the polymerization lasts 24 hours.
|Paintability after the application:||
The surface can be painted immediately after drying of the resin.
|Paintability with paints admixture:||
There is the possibility for the cement mortar or the cement to be painted with a paint admixture. For more information, please click here.

|4. Resistance of the applied product|
|Resistance to expansions and contractions, vibrations and earthquakes:||
Very good. The polymerized resin within the mass does not lose its shape nor is torn due to the movement and the internal frictions caused by such phenomena.
|Resistance to shocks and frictions:||Very good.|
|Behavior in acid and alkaline environment:||
The polymerized resin is not attacked by the alkaline environment which create for example the aggregates nor by the acid environment caused by the weather conditions, the plant roots etc.
|Resistance to temperature changes:||
Thanks to its elasticity the polymerized resin withstands sudden temperature changes.
|Resistance to extreme temperatures:||
Excellent, even at high heat and freezing cold conditions as those that occur only in certain areas of Northern Greece as far as Greece is concerned.
|Resistance to solar ultraviolet radiation:||Very good.|
|Resistance to constant contact with water or moist soil or other form of moisture:||After its polymerization the resin is not dissolved in water, however if left in continuous contact with water or humidity for several weeks it is likely to begin to emulsify. In practice, however, this possibility does not exist, because in all applications the mass within which participates this resin, after dried up, is covered by another resin of products family WINWET, which is not emulsified.|
|Tolerance to positive pressure:||High.|
|Tolerance to negative pressure:||Very high, thanks to the high adhesion of the cement mortar or the repairing cement contained in the resin. For this reason Betoplex is widely used both in construction of cement mortar for waterproofing of foundations, undergrounds, outer surfaces of tanks and other surfaces on which water exerts negative pressure, and in the manufacture of repair cement for the repair of broken parts or cracks on such surfaces, in combination with either common cement or fast setting cement, if there is continuous leakage.|
|Lifetime:||Unlimited. The polymerized resin does not lose its properties over the time, firstly because the material does not practically age (is not dried nor decomposed) and has high elasticity (does not lose its shape nor is torn with expansions and contractions) and secondly because in the mass is completely protected against the sun, the weather conditions and mechanical damages.|
|5. Natural properties of the product|
|Product form before its application:||Milky thin liquid.|
|Product form after its application and polymerization:||Single transparent, colorless, waterproof cohesive elastic mass diffused into concrete and other materials.|
|Air permeability and vapor permeability:||Yes, it allows transpiration, because the polymerized resin has such a molecular structure that does not allow the passage of water but allows the passage of air and water vapor between its molecules. This ensures the following key benefits:
1. The building is well ventilated and living in it is healthy and pleasant, because there is no smell (“musty”) or oxygen deficiency causing headaches, sleepiness, decreased performance, etc.
2. The tendency to form vapor condensation (droplets) and mold on the ceilings and walls is not deteriorated.
3. Thanks to adequate ventilation is avoided the gradual carbonization and weakening of the concrete that can occur when there is an increased concentration of CO2 in the building because of poor ventilation.
|Filling capacity of cavities and cracks:||Excellent, without leaving any gaps. Especially cast cement mortar fills itself all cavities without any effort by the technician.|
|Solubility in water:||The resin is dissolved in water, but this is unnecessary, it may be added to the blend as it is. Especially in repair concrete the water should be completely avoided.|
|Waterproofness:||Very good. No additive material may provide itself perfect waterproofness in the mass in which participates also water, as during drying of water is prevented cracking of the mass, however inevitably are created very small pores. To ensure absolute waterproofness of the mass, after drying, there should be a coating with a roller or a brush or spraying, to seal these pores, with one of the Betostal resins, depending on the type of the application.
The reduction in water permeability of the mass is proportional to the amount of resin to be added to the mixture of cement and sand and inversely proportional to the amount of water.
|Hydrophocity and oleophobicity:||No. To be achieved hydrophobic and oleophobic surface of the mass further of waterproofness, it is required a coating with Contraqua 7/50. For better adhesion of Contraqua 7/50 it can optionally be preceded by a coating with a resin of high adhesion (Betostal F/18) or high adhesiveness (Sovaplex DS), which functions as a primer, although the additive Betoplex generates by itself very good conditions for the adhesion of Contraqua 7/50.|
