Construction Chemicals

Main applications include concrete admixtures as water reducing additive. It has low dosage, low air content, high water reducing rate and applicable to most types of cement.

 It is used as cement grinding aid, to improve grinding efficiency, reduce energy consumption without compromising the performance of the cement. It is used as curing additives in cement admixtures.

Application:

• Triethanolamine is used as organic additive (0.1 wt%) in the grinding of cement clinker. It facilitates the grinding process by preventing agglomeration and coating of the powder at the surface of balls and mill wall.

• Triethanolamine is also used primarily as an emulsifier and surfactant. It is a common ingredient in formulations used for both industrial and consumer products. The triethanolamine neutralizes fatty acids, adjusts and buffers the pH, and solubilizes oils and other ingredients that are not completely soluble in water 

Natrosol™ hydroxyethylcellulose (HEC), a nonionic, water-soluble polymer, is a white, free-flowing granular powder. It is made by reacting ethylene oxide with alkali-cellulose under rigidly controlled conditions. Purified HEC for personal care and cosmetic applications is typically sold at 95.0 percent minimum purity (dry basis). 

Solutions of Natrosol HEC are pseudoplastic or shear-thinning. As a result, personal care products formulated with Natrosol HEC dispense rich and thick from the container, but spread easily on hair and skin. 

Natrosol HEC is easily dissolved in cold or hot water to give crystal-clear solutions of varying viscosities. Furthermore, low to medium molecular weight types are fully soluble in glycerol and have good solubility in hydro-alcoholic systems containing up to 60 percent ethanol. Natrosol HEC is generally insoluble in organic solvents.

Natrosol HEC is used as a binder, bond strengthener, cement extender, coating and optical brightener aid, coating polymer, filtration control additive, green strength enhancer, protective colloid, rebound or slumping reducer, rheology controller and modifier, lubricity and workability enhancer, suspension and stabilization agent, shape retention enhancer and thickener.

Natrosol HEC has applications in multiple markets including adhesives and sealants, advanced ceramics, building and construction, ceramics, pottery and porcelain, commercial and institutional, oil and gas technologies, metal castings and foundry, paint and coatings, personal care, pharmaceutical and pulp and paper.
