GD-115 Polyisobutylene Insulated Glass Sealant
Black PIB primary sealant for insulated glass units, with very low argon and moisture vapor transmission. PDF spec sheet available.
GD-115 is a black polyisobutylene (PIB) based sealant intended for use as a primary sealant in insulated glass units. It exhibits excellent long-term stability and remains permanently flexible, even at low temperatures.
GD-115 is designed to run well on high-volume, fully automated application equipment as well as on manual butyl extruders, and may be used with most commercially available silicone, urethane, polysulfide, or butyl hot melt secondary sealants.
