DOW has developed Dowsil 3363 silicone insulating glass sealant, engineered to facilitate narrow sealant joints without compromising on performance.

Even on facades with large glass elements, or where resistance to high wind loads and even blast resistance is essential, Dowsil 3363 insulating glass sealant enables economical joint sizes, the company said.

“Smaller joint dimensions can be filled faster and therefore lead to productivity enhancements which ultimately offers increasing transparency and design freedom for architects.”

Dowsil 3363 has been engineered for use as a secondary seal in demanding double, triple and gas-filled insulating glass applications. Its high design strength means traditional silicone IGU sealant joint size can be reduced by up to 30% on a wide range of substrates including coated and reflective glasses, aluminium and steel spacers, and a variety of plastics.

It is a two-part silicone sealant with a structural capability as a secondary sealant for insulating glass in structural glazing applications. It is UV resistant, provides long-term durability and excellent adhesion to glass and IG spacers.
