Modern architectural glazing requirements are extremely demanding regarding durability, energy efficiency and weatherproofing. successful long-term performance of a high-performance insulating glass unit (IGU) is greatly determined by the strength and durability of the sealing system.
IG-998 Insulating Glass Silicone Sealant provides reliable secondary sealing for double-glazed IGUs, offering good adhesion and high levels of long-term performance.
What is IG-998 Insulating Glass Silicone Sealant?
IG-998 is a Two-part neutral cure silicone sealant that has been developed as a secondary sealant for use in Insulating Glass Units. IG-998 has very strong adhesion to glass and aluminium surfaces without the use of a primer; therefore, it provides a faster, more efficient application process.
In both commercial and residential glazing applications, this sealant's remarkable resistance to UV rays, moisture, and temperature has been demonstrated, exhibiting good performance under demanding environmental conditions.
Additionally, it is packaged in 250 kg of base and 19 kg of catalyst, with black catalyst and white base colours. High-quality sealant like IG-998 ensures the insulating glass unit performs efficiently for years while reducing maintenance and replacement costs.
