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.
