27206-35-5 Usage
Description
Bis-(sodium sulfopropyl)-disulfide, also known as SPS, is a white to light yellow powder that is widely utilized in the electroplating industry. It is known for its ability to enhance the quality of copper coatings, making it a valuable additive in various applications.
Uses
Used in Copper Electroplating Industry:
Bis-(sodium sulfopropyl)-disulfide is used as a brightener for refining the crystal of the copper coating. It improves the current density in copper electroplating baths at a concentration of 10-50mg/L, resulting in a higher quality finish.
Used in Acid Copper Baths:
In the production of decorative and functional deposits, Bis-(sodium sulfopropyl)-disulfide serves as a brightening agent for acid copper baths. It is functionally compatible with most components of typical copper bath formulations, such as non-ionic surfactants, polymeric amines, and other mercapto compounds.
Used in Acid Copper Plating for Decorative and Functional Availability Coating:
Bis-(sodium sulfopropyl)-disulfide is also used in acid copper plating for applications like printed circuit boards. It can be combined with typical copper formulations, such as non-ionic surfactants, polyamines, and other thiol compounds, to enhance the quality of the coating.
Used in Combination with Dyes and Other Additives:
When combined with other additives like DPS and EXP2887, Bis-(sodium sulfopropyl)-disulfide can provide even better results in the electroplating process, making it a versatile component in the industry.
Flammability and Explosibility
Nonflammable
Check Digit Verification of cas no
The CAS Registry Mumber 27206-35-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,7,2,0 and 6 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 27206-35:
(7*2)+(6*7)+(5*2)+(4*0)+(3*6)+(2*3)+(1*5)=95
95 % 10 = 5
So 27206-35-5 is a valid CAS Registry Number.
