Product Data Sheet

DOWSIL™ 3363 Insulating Glass Sealant is a two-part, neutral curing silicone formulation for insulating glass applications.

Uses/Applications

• DOWSIL™ 3363 Insulating Glass Sealant is 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 (IG) 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.
• DOWSIL™ 3363 Insulating Glass Sealant is ideal as a secondary sealant for triple and double glazed units and meets EN 1279 requirements for gas-filled IG.
• DOWSIL™ 3363 Insulating Glass Sealant can be used in IG applications for structurally glazed facades. It is UV resistant, provides long-term durability and excellent adhesion to glass and IG spacers

Benefits

• Economical joint sizes in high strength IG applications
• High design strength (0.21 MPa) allowing joint size reduction up to 30%
• Enhanced productivity with reduced joint dimensions
• European Technical Approval (ETA13/0359)
• Suitable for gas-filled triple glazed units and gas-filled double glazed units
• Structural capability as secondary sealant for insulating glass in structural glazing applications
• Outstanding adhesion to a wide range of substrates including coated and reflective glasses, aluminum and steel spacers, and a variety of plastics
• Meets EN 1279 part 4 and 6 and EN 13022
• Tested according to EN 15434
• Meets the requirements of CEKAL
• Low water absorption
• Excellent temperature stability: -50°C to 150°C
• Non-corrosive cure
• Fast curing time
• Outstanding resistance to ozone and ultraviolet (UV) radiation
• High modulus which limits the stress on the primary sealant and makes it particularly suited for gas-filled insulating glass units
