2.Application

●Electroplating & metal surface treatment

Alkaline galvanizing bath solution: Disperses zinc ion impurities, serves as a carrier for brighteners, has low sulfate content that does not interfere with the passivation film,and remains stable in high-temperature baths at 50-75 ℃ for a long time with low foam

High-temperature alkaline spray degreaser (50-80℃) : Suspends oil stains and metal dust, prevents secondary contamination of workpieces, and ensures no excessive foam accumulation on the spray line.

Alkaline faded film, alkaline cleaning liquid medicine: PCB alkaline process cleaning agent (not used for brown liquid, alkaline damage brown membrane) alloy alkaline, imitation gold plating alkaline paste: scattered toner, high temperature without precipitation, without spots

 

●textile printing and dyeing

Disperse dyes/VAT dyes sanding and commercial filling: Strong grinding efficiency, refined dye particles, and reduced caking

Alkaline soaping agents,discharge/anti-whitening printing pastes, alkaline printing systems

Silk and wool blended blocking dyeing,VAT dye suspension pad dyeing (alkaline process)
 

●Paints, water-based inks,adhesives

Alkaline water-based industrial paint, anti-rust coating, alkaline color paste for electrophoresis: dispersed carbon black/inorganic pigment, no stratification after long-term storage

Water-based ink grinding, polyurethane water-based adhesive additive, reducing slurry viscosity and facilitating feeding

 

●pesticide formulation

Resistant to high-salt electrolytes, no caking or sedimentation during long-term storage

 

●other fields

Leather dyeing and tanning aid,papermaking filler dispersion, latex rubber stabilizer
