Welcome to our factory.

Shanghai Huihong Industrial Co., Ltd has been manufacturing wetting & dispersing agents, naphthalene sulphonate formaldehyde condensates since 1997. Production of wetting & dispersing agents are used for textile, dyestuff, pigments, construction superplasticisers, cement concrete admixtures, and water based pesticide formulation. Wetting agents series is specially Alkyl Naphthalene Sulfonates (ANS) based with excellent and unique properties to give very low foam during application with water. Dispersing agents seriers is Methyl and Napthalene sulfonic based products improve very well the separation of particles and prevent settling or clumping.    The surfactant are suitable for WP, WDG, SE, SC and are available in both liquid and solid form.
