S925
Silicone sealant
S925 is a high-performance silicone sealant for industrial applications. It cures from the outside in by absorbing moisture from the air under natural conditions, forming an elastic rubber after curing. It has high elasticity and excellent adhesion, and is suitable for sealing applications in aqueous environments.
Advantage
Neutral curing, non-corrosive to base materials
Acid and alkali resistant (pH 1-13)
Resistant to organic chlorine disinfectants (≤500ppm)
Extreme temperature tolerance (-40°C to 120°C)
