Stannous chloride dihydrate

CAS: 10025-69-1

Overview

Stannous chloride dihydrate (CAS 10025-69-1 ), also known as tin dichloride, is a tin(II) salt used across industrial manufacturing as a reducing agent, catalyst, and surface treatment chemical.

Its ability to donate electrons in controlled reactions makes it a practical choice for processes requiring metal deposition, dye fixation, or polymer stabilization in various sectors.

In textile and leather processing, it acts as a mordant to fix dyes onto fiber substrates, improving color fastness and uniformity in finished goods during the manufacturing cycle.

Printed circuit board and electroplating operations use it as a tin source and reducing agent for sensitizing non-conductive surfaces prior to the critical metallization phase.

In plastics and polymer production, it functions as a catalyst precursor for polymerization reactions and as a stabilizer component in PVC formulations for industrial applications.

Paper and packaging manufacturers apply it in flame-retardant treatments, where it contributes to reduced combustibility in coated substrates and specialized paper products.

Stannous chloride dihydrate is supplied as white crystalline powder or granules. Standard commercial grades include technical grade and reagent grade, with purity levels ranging from 98% to 99%+.

Some suppliers offer it to ACS or BP specifications depending on the end-use requirement. This ensures the material meets the necessary chemical standards for your specific facility.
