LEAD SULFAMATE Resistant O-Rings and Seals

Lead sulfamate, also known as lead (II) sulfamate, is a white crystalline powder commonly used in the production of lead-based compounds, such as lead chromate, lead oxide and lead chromate molybdate. It is also used as a curing agent in rubber production and as an inhibitor in the production of paints and coatings.

When rubber is exposed to lead sulfamate, it can cause adverse reactions such as swelling, softening, and cracking. This is due to the lead sulfamate's corrosive nature, which can break down the rubber's molecular structure and cause the rubber material to become brittle and weak over time. Additionally, the lead sulfamate can cause discoloration and staining on the rubber, which can make it difficult to maintain an aesthetically pleasing appearance.
