Structural Silicone Sealant, Brand Name : starsealant

Description
sts5900 two parts silicone structural sealant is a two component, neutral curing silicone sealant with high modulus and high strength, purposely designed for structural glazing for structurally 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
packageing
sts5900 is available as a “kit” consisting of a 47.6 us gallon drum of base and a 5 us gallon pail of curing agent (catalyst). Both the drum and pail are straightsided for use in commercially available pumping equipment.
