GE SSG4600 UltraGlaze*

GE SSG4600 UltraGlaze* is a high-strength, 2-part silicone elastomeric adhesive/sealant for use in structural glazing applications, specifically in the fabrication and shop glazing of curtainwall systems. GE SSG4600 UltraGlaze* is a two-component product (part A + part B) that provides fast adhesion and strength build; when mixed, GE SSG4600 UltraGlaze* cures quickly to a very high strength, tear-resistant durable silicone rubber.

  • Silicone durability – cured silicone rubber exhibits excellent long term resistance to natural weathering
  • Primerless adhesion – attains strong bonds to many conventional substrates and finishes without the need of a primer
  • Low pumping viscosity – provides for long longer pump life and reduced maintenance on equipment
  • Fast adhesion build – enhances early stability of assembled parts
  • Protective glazing – SSG4600 offers an excellent combination of strength, flexibility, and tear resistance to aid in countering the higher forces from hurricane, impact, and blast loads
  • Adjustable work life – variable ratio of parts A+B to accommodate assembly and application under varying conditions
  • High application rate – faster and more thorough joint filling capability with easier tooling effort
  • Catalyst options – non-flammable catalyst available in black or grey
  • Materials – compatible with many types of coated glass, metal finishes, glazing gaskets, setting blocks, and spacers
  • Packaging – 55 gallon drum base and 5 gallon pail catalyst

Basic Uses

  • SSG4600 is suitable for use in structural glazing applications such as factory glazing of curtainwall units and modules for unitized and panelized systems
  • SSG4600 is suitable for use as a weatherseal product, when movement expected in the joint does not exceed its movement capability (±25%)
  • SSG4600 is an excellent candidate for use in protective glazing applications
