What is Calcium Formate CAS 544-17-2?

Calcium Formate, also called calcium diformate, is an organic calcium salt with molecular formula Ca(HCOO)2. It is supplied as a white crystalline powder for cement-based dry-mix mortar and concrete formulations, not as a finished construction product.

Why is Calcium Formate used in cement-based systems?

Calcium Formate acts as a setting accelerator in cement-based mortars, tile adhesives and concrete. It can promote early strength development and help control setting behaviour, especially in colder conditions or where faster handling is required.

What is the water solubility and pH of Calcium Formate?

Calcium Formate is soluble in water at roughly 16 g per 100 g water near 0 deg C and about 18.4 g per 100 g near 100 deg C. Its dilute aqueous solution is generally near neutral to slightly alkaline, typically in the pH range of about 6-8.5 depending concentration.

How much calcium does Calcium Formate contain?

Commercial construction-grade Calcium Formate has a calcium content of approximately 36% by mass. This contributes to both the calcium supply and formate chemistry in the cement system, so dosage should be calculated for the specific dry-mix formulation.

Is Calcium Formate the same as Calcium Chloride?

No. Calcium Formate is an organic salt of formic acid, while Calcium Chloride is an inorganic chloride salt. They differ in setting behaviour, corrosion risk and formulation effects, so they are not interchangeable in mortar or concrete without testing.

Product Description

Calcium Formate CAS 544-17-2 is calcium diformate, with EC 208-863-7 and molecular formula Ca(HCOO)₂.

Synonyms: Calcium Diformate; Formic Acid Calcium Salt.

CAS: 544-17-2.

Molecular formula: Ca(HCOO)₂.

It is supplied as a white crystalline powder.

It is positioned as a construction additive for cement-based dry-mix mortar and concrete products.

It is a formulation raw material and is not a ready-mixed mortar, tile adhesive or finished concrete product.

It is used in cement-based dry-mix mortars and tile-adhesive systems.

It is used in renders, plasters and self-leveling construction materials.

It is used in concrete and precast-product formulations requiring a calcium-formate component.

It is used in specialty industrial formulations where calcium formate identity is specified.

It acts as a setting accelerator, promoting early strength development and helping control setting behaviour.

It is soluble in water, with dilute aqueous solutions generally near neutral to slightly alkaline, typically around pH 6-8.5.

Commercial construction-grade calcium formate has a calcium content of approximately 36% by mass.

Confirm assay, moisture, chloride and particle-size controls for the required construction-material route.

Store in tightly closed containers in a cool, dry, well-ventilated area.

Use suitable PPE when handling to prevent dust inhalation and skin or eye contact, and follow the current SDS.
