JB9980 Two Component Silicone Sealant For Insulating Glass
Overview:Junbond® JB9980 is a two- component neutral cured
silicone sealant specifically developed for the manufacturing of
insulating glass units used for window and door, vehicles and can
be used for edge frame curtain wall system. Feature:--Two
parts, neutral, high flexibility, high modulus with excellent
performance silicone sealant.--Excellent adhesion to a wide range
of curtain wall materials such as coated, enameled and reflective
glass, anodized oxidation orcoated aluminum and stainless
steel.--Neutral cured, no corrosion, non poisonous.--Excellent
stability in a wide range temperature at -50ºC~+150ºC.--Excellent
weatherproof feature and a high resistance to UV radiation, high
temperature and humidity. Application:--Cannot be used for
structural curtain wall glazing--It is formulated for making the
secondary seal in a dual sealed insulating glass unit.--The high
performance features incorporated into this product make it
especially suitable for the following applications:a) Insulated
glass unit for commercial buildings.b) Insulated glass unit
incorporating specialty glass types, or with free edges (solar
architecture)c) Insulated glass unit where high heat or humidity
maybe encountered.JB9980 sealant has excellent unprimed adhesion to
most coated or not coated glass. It is compatible to neutral serial
