IGS3723 Sealant
Outstanding adhesion and strength offer IGS3723 sealant as an ideal choice for edge seals in structural and non-structural insulating glass units. With first-rate flow characteristics, fast curing, and an adjustable work life, this two-part system can be considered for both automated and manual production lines.
IGS3723 sealant has a high-modulus, 100% silicone formula that meets American and European industry specifications and standards. You can depend on consistent resistance to UV rays, strong winds, and temperature extremes for decades of service life.
IGS3723 sealant is backed by world-class technical support and application-specific laboratory testing.
