Description

SEALANT-FC-295SG is a two-part silicone sealant for unitized curtain wall systems.  It is a fast-cure material with excellent adhesion to most glass and painted aluminum surfaces.  Once cured, this sealant becomes a high modulus and flexible silicone rubber suitable for structural and weatherseal applications.  This sealant contributes to the superior productivity and high reliability.

Features

  • Two-part and neutral-cure RTV* silicone sealant
  • Used with an airless mixing system, when mixed the material exhibits very high workability, even in low temperature environments
  • Mixing ratio: Adjusted to 10 (BASE): 1 (CAT) by volume
  • Cures very fast and features excellent adhesion to most common materials
  • Superior weather resistance to temperature change, moisture, ozone and ultraviolet rays

*RTV stands for ‘room temperature vulcanizing’ which means that this material can be cured at room temperature

SURFACE PREPARATION

All surfaces must be clean, dry, sound, and free from dust, oil, rust, or any other contamination.

Metals should be cleaned with a non-oily solvent soaked clean cloth, such as PROSIL CLEANER 1. Excess solvent should be wiped from the surface with a clean dry cloth. When used on remedial work all existing sealant must be removed. In some instances further cleaning or etching maybe required.
