Momentive RTV133 black, one-component, ready-to-use, silicone rubber adhesive sealant is recommended for evaluation in applications in the electronic, aerospace, appliance, transportation and other industries where resistance to burning of the finished product is a significant design consideration. On exposure to moisture in the air at room temperature, this adhesive sealant cures to a tough, durable, resilient silicone rubber. It utilises an atmospheric moisture cure system, which releases an alcohol vapour from the sealant surface during cure. RTV 133 sealant offers low odour cure with no unpleasant smell or pungent cure by-products. It is, however, somewhat slower curing both in tack-free time and cure-through time than atmospheric moisture cure silicone adhesive sealants which give off acetic acid vapours as a cure by-product. Because RTV133 sealant has a paste-like consistency and will flow only with external pressure, it is suitable for use on horizontal, vertical and overhead surfaces in thicknesses to 6mm (¼ in.). It has sufficient uncured body to adhere to small objects while cure is taking place. For applications requiring sealant thickness greater than 6mm (¼ in.), Momentive Performance Materials one-component, addition cure or two-component silicone rubber compounds with similar properties are available. As Momentive RTV133 is a one-component product, there is no mixing required, which aids its ease of use. RTV133 had a thixotropic paste consistency and offers a low flammability-has a UL rating of V-0 or V-1 using UL-94 test. RTV133 has the capability to cure at room temperature and ambient humidity conditions and offers self adhesion properties & resistance to high temperatures whilst maintaining low temperature flexibility. Momentive RTV133 has excellent weatherability and ozone and chemical resistance and offers excellent electrical insulation properties.
