DOWSIL™ 3363 Insulating Glass Sealant

A high strength secondary two-part silicone sealant specifically designed for high strength applications, where conventional sealants with lower strength would lead to increased joint sizes. It enables economical joint sizes in highly demanding insulating glass applications such as: high wind in tall buildings, hurricane loads, cold-bent glass or high impact loads such as bomb blast. Smaller joint dimensions can be filled faster and therefore lead to productivity enhancements.

Uses:

  • High strength applications, where conventional sealants with lower strength would lead to increased joint sizes
  • Enables economical joint sizes in highly demanding insulating glass (IG) applications:
    • High wind in tall buildings
    • Hurricane loads
    • Cold-bent glass or high impact loads such as bomb blast

Benefits:

  • Economical joint sizes in high strength IG applications
  • High design strength (0.21 MPa) allowing joint size reduction up to 30%
  • Low water absorption
  • Excellent temperature stability
  • Non-corrosive cure
  • Fast curing time

Benefits and Capabilities of DOWSIL™ 3363 Insulating Glass Sealant

How is this possible?

DOWSIL™ 3363 Insulating Glass Sealant has been engineered specifically for use as a secondary seal in demanding double, triple and gas-filled insulating glass applications.

With a 50% higher design strength (0.21 MPa with European approval)*, DOWSIL™ 3363 Insulating Glass Sealant enables more economical, yet stronger, jointing in demanding tall building design and construction, thereby increasing transparency and design freedom.

Stress on the primary sealant is limited thanks to the high strength of DOWSIL™ 3363 Insulating Glass Sealant, thus adding to the façade durability and longevity.

The high strength of DOWSIL™ 3363 Insulating Glass Sealant ensures:

  • Suitability for demanding applications such as the retention of large glass elements, resistance to high wind and hurricane loads and blast resistance 
  • Productivity enhancement as larger joints can be reduced by up to 30%, hence joints can be filled faster

*50% higher than conventional structural silicones with a design strength of 0.14 MPa
