Naphthalene Superplasticizer

 Formaldehyde is commonly referred to as a concrete superplasticizer. It is particularly well-suited for the production of high-strength concrete, steam-cured concrete, flowing concrete, impermeable concrete, waterproof concrete, plasticized concrete, as well as reinforced steel bars and prestressed concrete structures. Furthermore, sodium naphthalenesulfonate formaldehyde can also serve as a dispersant in industries such as leather, textiles, dyes, and others. As a leading in China, Kingsun consistently delivers top-notch products to meet the needs of our customers.

Application Method And Precautions of Naphthalene-based Superplasticizer

The range of blending dosage is 0.5-1.2%. When using, the appropriate blending amount can be selected according to the engineering object and the materials used.

FDN powder is recommended to be used in the form of solution. It can be used in dry form, but make sure to mix it well with the concrete.

If the product is used by static water blending method or post-blending method, the water-reducing dispersion effect will be better.

This naphthalene sulfonate superplasticizer product can be compounded with other types of concrete admixtures. It can be "double blended" with fly ash, ground slag and other admixtures, but the amount should be calculated according to the total amount of cementitious materials.

When using this product for the first time or changing the cement type, concrete trial preparation should be carried out according to the materials used and site construction requirements. Adjust the construction mix ratio according to the test results as a guide for construction coordination.
