Why would a dentist choose a polycarboxylate cement instead of zinc phosphate to permanently cement a crown?
A dentist may choose a polycarboxylate cement over zinc phosphate for cementing a crown if the tooth is sensitive to temperature changes since polycarboxylate cement has better thermal insulation properties. Additionally, polycarboxylate cement releases fluoride, which can help prevent decay around the tooth.
What are the ingredients in Jet Dry?
Jet Dry typically contains ingredients such as water, citric acid, sodium polycarboxylate, and surfactants. These ingredients help to reduce water spots and improve drying performance in dishwashers.
What are the ingredients used to manufacture skim coat and concrete admixtures retarders and superplasticisers?
Skim coat typically consists of a mixture of cement, fine aggregates (like sand), and water, often with additives to enhance workability and adhesion. Concrete admixture retarders usually include organic or inorganic compounds that slow down the setting time of concrete, such as sugars or certain types of acids. Superplasticizers, on the other hand, are made from synthetic polymers that improve the fluidity of concrete without adding extra water, often based on sulfonated naphthalene or polycarboxylate derivatives.
What types of superplasticizers are divided into?
Five main types of new water reducers: (1) Polycarboxylic acid water reducer (2) Naphthalene water reducing agent (3) Sulfamic acid series water reducer (4) Modified lignosulfonate to reduce water (5) Hybrid water reducer

What is the difference between made of and made from?
"Made of" and "Made from" can mean the same thing. "That can is made from aluminum." "That can is made of aluminum." However, they can't be used the same in every situation. You can say: "That house is made of wood and made from workers." But you can't say: "That house is made of workers and made from wood."
