Cement grinding aid & concrete admixture:
DEIPA is primarily used as a cement grinding aid as it prevents cement particles
from re-agglomerating during and after the grinding process, resulting in process increasing process time efficiency, material uniformity and decreasing energy cost. DEIPA can be used as an admixture in cement to significantly increase the early and final strength of concrete. It is preferred as a grinding aid more than TIPA and TEA.
Concrete modification: Improving workability, reducing slump loss, suitable for high-strength / ready-mixed concrete.
Metalworking fluid: Acts as corrosion inhibitor and pH buffering agent.
Coatings & inks: Used as curing agent and pigment dispersant.
Gas treatment: Absorbs acid gases such as H鈧係 and CO鈧.
Drilling fluids: Inhibits shale hydration and stabilizes wellbores.
Balanced performance in grinding aid, early strength and strength enhancement
Low toxicity, biodegradable and environmentally friendly
Good compatibility with various cementitious materials and additives
Low dosage, high cost-effectiveness
Avoid contact with skin and eyes; wear protective goggles and gloves during operation.
Product should be stored in a dry place in sealed, original packaging away from direct sunlight and strong acids and oxidizers.
Transport as general chemical cargo.
