STS590 High Performance Structural Glazing Silicone Sealant

DESCRIPTION

STS590 is a one-component, neutral curing silicone sealant designed and tested for structurally glazed curtain wall applications. The material is supplied as a paste, which cures into an extremely tough elastomeric silicone rubber ensuring a durable, flexible, watertight bond upon exposure to atmospheric moisture.

CHARACTERISTICS

100% silicone, no sag;

RTV-1. Good extrusion and thixotropy between 4℃~+40℃. Easy to use;

Neutral cure, high tensile strength, fast curing；

Excellent resistance to weather & water;

Remains flexible over a temperature range of -58°F(-50°C) to 302°F(150°C)

Successfully tested for use in protective glazing applications;

Excellent adhesion to glass and ceramics;

Good compatibility with other neutral silicone sealants;

25% movement capability.
