Momentive RTV-133 Sealant - 10.1 oz | RTV133-10-10Z
RTV 133 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 utilizes a moisture vapor cure system, which releases an alcohol vapor from the sealant surface during cure. RTV133 sealant offers low odor 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 moisture vapor cure silicone adhesive sealants which give off acetic acid vapors as a cure by-product.
Because RTV 133 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.
