STS5900 RTV2 Neutral Two Parts Silicone Structural Sealant

STS5900 Two Parts Silicone Structural Sealant

DESCRIPTION

STS5900 Two Parts Silicone Structural Sealantisa two component,neutral curing silicone sealant with high modulus and high strength, purposely designed for structural glazing forstructurally glazed curtain wall applications.Both component of STS5900 are thixotropic pastes and, while mixed, cure quickly to an extremely tough elastomeric silicone rubber and sealant at room temperature. It can bond to most substrates withou primer and also ensure a durable, flexible, watertight bond.

APPLICATIONS

Silicone structural glazing in curtain wall

Structural attachment of many panel systems

Protective glazing applications

Pane stiffener applications
