1.3. Details of the supplier of the safety data sheet Henry Schein, Inc. … Polycarboxylate Superplasticizer. Polycarboxylate Superplasticizer is used as a high range water reducing admixture in high performance concrete, high strength concrete, high volume fly ash/slag concrete, cement grouting, and dry mortar. These polymers are used as dispersants, especially for early strength concrete, to avoid particle segregation. Related to polycarboxylate cement: zinc phosphate cement pol·y·car·box·y·late ce·ment a powder containing primarily zinc oxide mixed with a liquid containing polyacrylic acid that reacts to form a hard crystalline mass on standing; when used to lute metal castings to teeth, it has the potential of bonding to the calcium contained in tooth structure as well as to any base metals contained Polycarboxylate ether is a superplasticizer admixture. It can be used to prepare high-performance concrete and high strength concrete. Adding polycarboxylate ether-based superplasticizer in concrete or mortar can reduce the water-cement ratio.

Silicophosphate cements are a combination of silicate and zinc phosphate cement. They have been used as a filling material and for indirect restoration material as an alternative to amalgam. Polycarboxylate cements have good pulp compatibility; however, they may cause pain after their application. Polycarboxylate cement is considered the most biocompatible type due to having the most rapid pH rise. Provide a good marginal seal to prevent marginal leakage. Resistant to dissolution in saliva, or other oral fluid – a primary cause of cement failure is dissolution of the cement at the margins of a restoration. Polycarboxylate cement (sometimes called polyacrylate cement) is a permanent cement also used as an insulating base.
May also be used for cavity lining under all restorative materials, temporary fillings and fillings in deciduous teeth. Composition : Powder : Zinc Oxide, Magnesium Oxide, and Sodium Fluoride.

Their high chelating power, even at low concentrations, reduces deposits on the laundry and inhibits the crystal growth of calcite. Polycarboxylate ethers (PCE) are used as superplasticizers in concrete production. Safety. Polycarboxylates are poorly biodegradable but have a low ecotoxicity. Invented in 1968, zinc polycarboxylate cement was the first cement to exhibit a chemical bond to tooth structure.
