Product Overview
Sodium salt of polynaphthalene sulphonic acid is a brownish liquid or Light yellow powder. It is an anionic surfactant and can be used concurrently with both anionic and nonionic surfactants. It is resistant to acids, alkalis, hard water and salt. It has good diffusion and protective colloidal properties, and no paint penetration or foaming. It has affinity for proteins and nylon fibers, but no affinity for cotton and linen fibers. It can be mixed with other surfactants alone and is used as a dispersant for color dyes and a softener for reactive dyes in the manufacturing of color dyes. It can also be used as a uniform dyeing agent in textile dyeing. In the leather industry, it is used as a softening agent. It can also be used as a water reducer for cement concrete, significantly enhancing the early strength and drying time of cement. Our company's products are mainly used as stabilizers for latex in the synthetic rubber industry.
