WATER REDUCER POWDER
Sodium Naphthalene Sulfonate Formaldehyde is made of naphthalene, sulfuric acid, formaldehyde and liquid alkali. After sulfonation, hydrolyzation, condensation, neutralization reactions, finally dry to a powder. Sodium Naphthalene Sulfonate Formaldehyde can be used in a variety of applications as a high efficient superplasticizer, which is widely applied in the cement, construction and gypsum industries. Visight provides Sodium Naphthalene Sulfonate Formaldehyde with excellent water-reducing and dispersing properties. It can markedly reduce the amount of water and significantly increase the strength of cement, concrete and gypsum at various ages. Not only save cement, improve concrete workability, but also speed the construction progress up.
