MAGNESIUM FORMATE

A water-soluble magnesium salt of formic acid for specialty chemical synthesis, materials development, research and evaluated industrial formulations.

Mg(HCOO)₂ CAS 557-39-1 · Anhydrous Specialty Formate Salt

A versatile bridge between magnesium and formate chemistry.

Magnesium Formate combines a divalent magnesium cation with formate anions. It is offered for customers developing specialised chemical, analytical and material systems where a defined magnesium source and formate functionality are required.

Magnesium Formate is chemically distinct from Calcium Formate. Construction acceleration, strength development and dosage claims should not be transferred from Calcium Fo

Product FAQ

Frequently Asked
Questions

Key questions regarding Magnesium Formate identity, hydration state and formulation-specific performance.

Is Magnesium Formate the same as Calcium Formate?
No. They contain different divalent metal ions and must not be assumed to give the same formulation or cement performance.
Why does the hydration state matter?
Dihydrate contains two waters of crystallisation and has a higher molecular weight, changing active salt content and process stoichiometry by weight.
Can it be promoted as a construction accelerator?
Only after Geocon generates formulation-specific set-time and strength data demonstrating that performance in the target cement system.
