cafo Calcium Formate, is an additive for improving the performance and quality of construction chemicals and compounds. When it is used in construction industry, you can;

  • increase the open time
  • accelerate setting & hardening

cafo Calcium Formate, increases water stability which means that your application can be more durable in humid conditions such as pools, bathrooms, etc.

Increasing open time

Applying cafo Calcium Formate in construction industry (especially in adhesives) extends considerably open time property of applications. By this improvement, craftsman can enlarge application area and have a significantly more productive working method.


  • Tile adhesives
  • Concrete cure accelerator
  • Leather tanning
  • Feeding industry

*By using cafo Calcium Formate, open time value is more than double in comparison with the usual property.

Key features

  • Increases water stability, this property ensures more stability even under tough conditions like high humid environments.
  • With its optimal particle size, it can be dissolved very easily and efficiently.
  • Chloride-free, odorless, environmental and health friendly.

Improving adhesion

Applying cafo Calcium Formate in construction industry improves adhesion of application, especially adhesion from material to surface of application area. Adhesion property is directly in relation with longer open time, the longer open time, the better adhesion results.
