Usage:
The largest use for inorganic tin compounds is in electrolytes for plating tin and tin alloys. The more important plating chemicals are chlorides, sulfates, and fluoroborates in acidic electrolytes and stannates in alkaline solutions. Inorganic-tin compounds are divided into two series: stannous, or tin(II), compounds and stannic, or tin(IV), compounds.Chemically, tin exhibits valencies of 2 and 4. It resists attack by water but is dissolved by strong acids and alkalis.
Storage: Store in shady, cool, low temperature and well ventilated warehouse of incompatible materials. Keep away from fire, static electricity, sparkle, hot source (such as vapor tube flue equipment). Out of direct sunlight, avoid contacting strong acid, strong base, sulfides, deoxidizer, catalyst promoter for polymerization and accelerates when be stored and delivered. Protect from impact, blow, shake, or friction. Hold water content.
