1-Part Silicone

GD-823N is a neutral curing one-part silicone sealant that reacts with atmospheric moisture to form a durable and flexible secondary seal. GD-823N is particularly suitable for sealing insulated glass units that have exposed edges such as windows in commercial buildings, greenhouses and conservatories. Like any silicone sealant, GD-823N cannot be used in the manufacture of gas-filled units without a PIB primary sealant. GD-823N is particularly suitable as a secondary edge seal in multipane insulating glass units.

GD-823N is supplied as a one-part, ready to use material. The product is available in pails or drums. Application is possible by using standard industrial dispensing equipment.

GD-823N is solvent-free and offers the following features and benefits:
  • Excellent adhesion to float, tinted or coated glasses as well as to many plastic and metal spacers
  • Remains flexible at both high and low temperatures for good gunnablity
  • Excellent resistance to weathering and UV effects
  • High extrusion rate allow for use on high-speed automated assembly lines
GD-823N can be processed on high speed automated lines.

As a secondary edge sealant, silicone offers the best UV and weathering protection on the market, making it ideal for greenhouse or other structures with exposed edge seals.
