APPLICATION NOTES:
- MC-PowerFlow 2290 is a new generation of a superplasticizer based on modified polymer polycacboxylate ether with high water reduction causing highly workability with low water content.
- Allows the production of high quality concrete, concrete requiring long slump retention and very high early age strengthening concrete for DUL items.
- Longlasting slump retention ensures long-distance transport.
- It can be mixed directly into measured water before adding to dry concrete mix or added to wet mixed concrete, should be mixed for at least 1 minute.
- Trial mixes are recommended to establish exact dosage rates required to suit individual requirements. When accidental overdosing occurs, the set retarding effect increases. However, the final strength will not be affected if this period has right curring.
- We can provide accurate dispensing equipment upon request.
- Use an appropriate mixer and do not mix by hand. If assistance is required, please contact our Technical Service Department.
- Can be combined with all MC-BIFI products but must be mixed separately.
- Can be used with all standard cement types as well as sulfate resistant cement.
- Does not contain any hazardous substances. It is safe to use with standard precautions followed in the construction industry, such as use of hand gloves, safety goggles, etc.
- Avoid contact with foodstuffs and utensils. Avoid prolonged skin contact. In case of contamination, it should be thoroughly rinsed with water. When splashed into eyes or mouth, wash thoroughly with clean water and obtain medical attention immediately.
