RTV Silicone Rubber T-442 |
 |
RTV Silicone Rubber T-442 is a one-component, thixotropic sealant intended for use where a soft, high elongation material is desired. T-442 is particularly effective as an adhesive in applications where the bonded joint is subjected to relatively large movements in service. * Tenacious adhesion to most metals, plastics, synthetic rubbers, glass and concrete * Low modulus of elasticity for superior sealant joint movement capability * Low compressive modulus, ideal for forming compression gaskets on covers and closures where low clamping pressures are essential * Stays flexible between -65'F and 400'F * Impervious to weathering and ultraviolet degradation * Resistant to hot lubricating oils * Causes little or no foam in lubricating oils * Non-corrosive to ferrous metals |
