JB8800 Two Component Structural Silicone Sealant
Overview:Junbond® JB8800 is a two component, neutral curing
silicone sealant for structural applications. It has good adhesion
with wide range of surfaces without the need of priming and
professional quality. 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 or coated aluminum and stainless steel.--High level of
mechanical properties with joint movement capacity of
±12.5%.--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:--Structural glazing
applications such as: used for structural adhesion and seal the
joints of the structural glass and metal in the factory or building
site.--Assembly of curtain walls glass material or stone
material.--Assembly of glass construction project.--Assembly of
windshield of car and ship.NO.ITEMSPECIFICATIONTEST RESULT 1
