Product Description
RUNTAI WEATHERPROOF NEUTRAL SILICONE SEALANT 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.
Key Features -One part, neutral, room temperature curing.-High flexibility, high modulus with excellent performance.-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 inthe factory or building site.-Assembly of curtain walls .-Assembly of glass construction project.Application Restrictions-RT-8500 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.-When the surface's temperature is below 4ºC or above 40ºC .-To materials contained copper or copper alloy, painted surface, which may cause paint cracking or paint stripping.-To the surfaces with lime power, concrete or sand again.-Please read company's technical files before application. Compatibleness test and bonding test must be done for construction materials before application. PRODUCT PARAMETERS | | ITEM | SPECIFICATION | TEST RESULT |
