Diethanol Isopropanolamine 85% (DEIPA 85%) – High-Performance Cement Grinding Aid
Diethanol Isopropanolamine 85% (DEIPA 85%) is a highly efficient organic compound widely used as a cement grinding aid and performance enhancer in the construction and chemical industries. Known for its ability to increase cement fineness, improve strength development, and reduce clinker consumption, DEIPA 85% has become a preferred additive among manufacturers seeking cost efficiency and sustainability.
At City Chemicals EU, we supply high-purity DEIPA 85% to clients worldwide, ensuring consistent quality, safety, and compliance with international standards.
What is DEIPA 85%?
DEIPA (Diethanol Isopropanolamine) is an alkanolamine compound used primarily as a cement additive. It belongs to the family of amine-based chemicals designed to enhance cement grinding efficiency and improve the mechanical properties of concrete.
At 85% concentration, DEIPA offers optimal balance between performance and stability, making it a reliable choice for large-scale cement production.
How DEIPA Works in Cement Production
When introduced during the cement grinding process, DEIPA 85% reduces the surface energy of clinker particles, preventing agglomeration and improving mill efficiency. This leads to:
-
Faster grinding cycles
-
Higher cement fineness
-
Reduced energy consumption
-
Improved early and late strength of cement
DEIPA also works as a substitute for Triethanolamine (TEA) and Triisopropanolamine (TIPA), providing superior performance in terms of compressive strength gain at both early and later stages.
Benefits of Using DEIPA 85%
-
Improved Grinding Efficiency – Enhances cement mill performance.
-
Strength Development – Promotes early and long-term compressive strength in cement.
-
Reduced Clinker Usage – Lowers raw material cost and carbon footprint.
-
Energy Savings – Optimizes grinding process, lowering electricity demand.
-
Sustainable Solution – Supports green cement production with reduced emissions.
-
Versatile Application – Suitable for Portland cement, blended cements, and slag cements.
Safety & Handling
DEIPA 85% is generally safe when handled according to industrial chemical guidelines. Users should wear protective equipment (gloves, goggles, masks) and follow standard chemical handling procedures. Avoid direct skin contact and prolonged inhalation.
Longevity & Shelf Life
When stored properly in sealed containers at room temperature, DEIPA 85% has a shelf life of 12–24 months without loss of performance.
