Curtain Wall Caulk Construction Glass Weatherproof Neutral Cure Silicone Sealant

Product Description

RT-8500 STRUCTURAL SILICONE SEALANT FOR CURTAIN WALL

Overview

RT-8500  is  a  ready  to  use,  one  component,  neutral  fast  curing  silicone  sealant  for structural  applications.  It cures  at  room temperature  by  the  action  with  atmosphere moisture to become a permanently flexible silicone sealant. It has good adhesion with wide range of surfaces without the need of priming and professional quality.

PRODUCT FEATURES

·  Single Component,neutral curing,high adhesion,medium and high modulus,with strong displacement capacity;
·  It can obtain excellent bonding and sealing performance without primer with most building materials,and has good extensibility,water tightness and other functions;
·  After curing,the product forms a cold resistant,heat-resistant and corrosion-free elastomer,which has excellent weather resistance,aging resistance,ultraviolet resistance,ozone resistance and high and low temperature resistance,and has no pollution to the environment;
·  It has good compatibility with other silicone adhesives of Runtai.

APPLICATION AREA

·  Structural bonding,assembly and sealing of glass curtain wall,stone(marble,granite) curtain wall,aluminum curtain wall and metal structure engineering;
·  It is applicable to the staggered connection or butt joint between glasses,the second bonding and sealing of lighting roof and hollow glass;
·  Sealing and bonding in high-rise buildings and industrial applications;
·  It is applicable to curtain wall design of semi concealed frame or fully concealed frame projects and other types of building and industrial sealing.
