Product Description of Aluminium potassium sulfate dodecahydrate CAS#7784-24-9
Aluminum potassium sulfate dodecahydrate is an industrial-grade product with a purity of ≥99.5%. It occurs as colorless crystals or white odorless powder. It has a melting point of 92.5 °C and decomposes when heated to boiling. Its vapor pressure is negligible at 25 °C, with a relative density of 1.757 at 20 °C. It is freely soluble in water, yet insoluble in ethanol. The product remains stable under conventional conditions, but is incompatible with strong bases and should be stored separately from them.
Product Application of Aluminium potassium sulfate dodecahydrate CAS#7784-24-9
Aluminum potassium sulfate dodecahydrate is a white, water-soluble crystal. It is prepared by roasting alunite in a furnace followed by crystallization purification. In traditional photography, it is used to harden gelatin emulsions. It can be applied by adding into the emulsion, bathing exposed photographic plates prior to development, or incorporating into the fixing bath. Furthermore, when compounded with citric acid or other acids, it can be formulated as a clearing bath to remove developer stains from photographic negatives.

Dispersed PVC Resin
White fine powder
Polyvinyl chloride paste resin, also called dispersed PVC resin, is a fine white powder designed to disperse in plasticizers. Its small primary particles produce homogeneous plastisols for coating, impregnation, and casting. Applications include artificial leather, wallpaper, vinyl toys, gloves, automotive interiors, adhesives, and coatings requiring a workable paste-based processing route.![Xylene]( "Xylene")
XyleneXylene
Colorless liquid
Xylene is a clear, colorless aromatic hydrocarbon liquid with a characteristic odor. Insoluble in water but compatible with many organic solvents, it dissolves resins, oils, and rubber while providing useful evaporation behavior. It serves as a coating thinner, ink solvent, resin-processing medium, adhesive ingredient, and industrial cleaning solvent.![Ethyl acetate]( "Ethyl acetate")
Ethyl acetateEthyl acetate
Colorless liquid
Ethyl acetate is a clear, colorless ester solvent distinguished by its fruity odor and rapid evaporation. It mixes with ethanol, ether, and other organic solvents while having limited water solubility. Its solvency for oils, resins, and organic materials supports coatings, printing inks, adhesives, extraction, leather processing, and industrial cleaning.![Sodium Lauryl Ether Sulfate(SLES)]( "Sodium Lauryl Ether Sulfate(SLES)")
