RTV 133

An excellent candidate to consider for use 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 stratospheric moisture cure system, which releases an alcohol vapour from the sealant surface during cure.

RTV133 sealant offers generally low odour cure with virtually no unpleasant smell or pungent cure by-products. It is, however, somewhat slower curing both in tack-free time and cure-through time than many atmospheric moisture cure silicone adhesive sealants that 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 may be considered for use on horizontal, vertical and overhead surfaces in thicknesses to 6mm in.). It has sufficient uncured body to typically adhere to small objects while cure is taking place.

For applications requiring sealant thickness greater than 6mm in.), Momentive Performance Materials one-component, addition cure or two-component silicone rubber compounds with similar properties are available for consideration.
