Product:
DOWSIL™ 3540 Silicone Sealant has been designed to provide a secondary seal in a dual sealed insulating glazing unit. The primary seal is typically made of polyisobutylene. It has a high green strength making it possible to handle the unit quickly and a high cure rate (4.0mm in 24 hours) as a one-component sealant. When cured it has a high modulus for a good mechanical assembly of insulating glazing. Available in black and light gray in drums, in black in all other container sizes.
DOWSIL 3540 Silicone Sealant is a neutral cure sealant, offering several advantages over acetoxy silicone formulations:
– Consistent adhesion to both aluminum spacers and glass
– No corrosion of the coating on glass, the metallic spacer or the PVB foil of laminated glass
– Reduced Vapor Transmission Rate (low Penetration Rate Index ‘I’)
– Compatibility with butyl used as primary seal
– High strength of bond due to its high modulus of elasticity.

Features & benefits:
– Excellent adhesion to coated or reflective glass, aluminum or galvanized steel spacers
– Fast cure one-component technology, ideal for use at low temperature and/or low humidity in workshops
– Minimum waste and downtime by eliminating base purging and static mixer maintenance
– Packaged for both manual and robot applications
– Outstanding aging properties
– Silicone technology providing outstanding UV resistance
– Service temperature range -40°C (-40°F) to up to 100°C (212°F)
– Non-slumping, permitting ease of both manual and automated glazing
– Non-corrosive cure
– Solvent-free
– Low water absorption
– High level of mechanical properties
– Does not contain organic plasticizer that can cause fogging in the IG air space
– Resistant to ozone

Applications:
– Insulated glazing for residential and commercial glazing.
– Insulated glazing incorporating specialty glass (pyrolithic of soft coated, laminated, tinted, enameled) types, stepped glass or with free edges.
– Insulated glazing for applications under extreme conditions of humidity and temperatures, high or low.
– Insulated glazing used in greenhouses and skylights under high sun exposure.
– Adhering and jointing of glass elements.

– 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
– 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

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.
