GARDISPERSE® 820L – Calcium Naphthalene Sulfonate Formaldehyde Polymer

Calcium NSF Superplasticiser in liquid form. Used as water reducing agent to increase strength of concrete or reduce drying time for plaster board. Calcium neutralised for applications requiring low sodium content.


Calcium Naphthalene Sulfonate Formaldehyde Polymer is a liquid superplasticizer designed for the construction industry. This product serves as a water reducing agent to increase the strength of concrete and reduce the drying time for plasterboard.

Unlike other superplasticizers that use sodium as a neutralizing agent, Calcium NSF Superplasticiser uses calcium, making it ideal for applications that require low sodium content. This makes it an excellent choice for projects that require environmentally friendly and sustainable construction materials.

When added to concrete, Calcium NSF Superplasticiser improves workability, increases flow and reduces water content. The result is stronger, more durable concrete that is easier to handle and finish.

Similarly, when added to plasterboard, this product reduces the drying time, making it faster to install and finish. It also improves the workability of the plaster, resulting in a smoother, more consistent finish.

Calcium Naphthalene Sulfonate Formaldehyde Polymer is a versatile and reliable product that has been proven to enhance the performance of concrete and plasterboard. Its liquid form makes it easy to use and ensures that it can be easily incorporated into a wide range of construction applications. Its calcium neutralization also makes it an ideal choice for projects that require low sodium content.
