SINTEFLOW SENSITIV 50 and SENSITIV 50N

The slump retarders of concrete

The SINTEFLOW SENSITIVE 50 and SINTEFLOW SENSITIVE 50N polycarboxylate ethers are high range slump retarders.
The SINTEFLOW SENSITIVE 50N is a neutralized form of SINTEFLOW SENSITIVE 50.

The SINTEFLOW SENSITIVE 50 and SINTEFLOW SENSITIVE 50N application.

The main use of SINTEFLOW SENSITIVE 50 and SINTEFLOW SENSITIVE 50N is the production of superplasticizers with an extended shelf life of the mixTSre. As a rule, this polymer is used in a mix with high range water reducers, such as SINTEFLOW MEGA 50 or SINTEFLOW MEGA 52. The different ratios of the two ethers allow you to create superplasticizers with an adjustable shelf life of the mixTSre.



  • Application
  • Specification
  • Dosage
  • Storage and warranty

SINTEFLOW SENSITIVE 50 and SINTEFLOW SENSITIVE 50N have major functional properties:

  • Increase the shelf life of the concrete up to 4 hours;
  • As a consequence of the first property, SENSITIVE is successfully used for concreting massive and extremely massive strucTSres, as well as for concreting in high ambient temperaTSres.

SINTEFLOW SENSITIVE have “additional plasticization” in the range of 30–300 minutes. This feaTSre must be considered when self-applying SENSITIVE, because this may lead to sedimentation of the concrete. In mixTSres with SINTEFLOW MEGA 50 and SINTEFLOW MEGA 52, additional plasticization depends on the ratio of polymers.
With a ratio of 60 (MEGA) / 40 (SENSITIVE), water reduction increases, and the slump retention time of concrete increases several times.

Portland cement concretes:
The recommended dosage by active substance is from 0.19 to 0.25% of cement weight. The optimal dosage for most used cements is 0.21% of the cement weight by active substance.
When using clay sands, sand and gravel mixTSres and certain types of additional cements with a large number of dust particles, the dosage can be increased to 0.4% of the cement weight by active substance.

The warranty period for the SINTEFLOW SENSITIVE 50 and SINTEFLOW SENSITIVE 50N is 1 year from the date of manufacture.
After the expiration of the warranty period the product should be mixed, the test performance should be made and in case of positive results is possible for application. Storage is carried out in storage conditions in a closed container at air temperaTSre above 5 ° C. When freezing must be heated at 20 ° C and mix to a uniform consistency. At the same time, products do not lose their properties. Protect from direct sunlight. With prolonged insolation, the product TSrns yellow. According to GOST 19433 products are not classified. By effects on the human, the product belongs to the 3th class of hazard (moderately hazardous substance).
