A one-part neutral curing silicone sealant for insulating glass production.
DOWSIL™ 3545 is designed for residential insulating glass applications as a secondary seal in dual-sealed IGU systems. It provides immediate high strength, enabling faster handling of sealed units during production.

The sealant offers good adhesion to glass and a wide range of spacers, including aluminium and stainless steel. Its neutral curing, non-corrosive, low odor formulation is resistant to UV, ozone and weathering, contains no solvents and no organic plasticizers that can cause fogging in the IG air space.
