Overview
RT-9500 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.
Features
Two part, 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.
Use Limitations
RT-9500 silicone sealant should not be applied in the following conditions:
To all surfaces that bleed oils, plasticizers or solvents, and some uncured or sulfurized rubber.
To the unventilated space or the surface which can touch the food or water directly.
Please read company 's technical files before application. Compatibleness test and bonding test must be done for construction
materials before application.
