Abstract: A device, e.g., an electrical or electromechanical assembly, comprising a housing with a mechanism disposed therein which is potted by a cured mass of a self-leveling liquid composition. The composition comprises an actinic radiation cured first resin component and a subsequently cured second resin component which is non-cured under the actinic radiation conditions effective for curing the first resin component. Also disclosed is an appertaining method of making such devices.Depending on the depth of the composition which is to be cured in the housing, it may be desirable to utilize the self-leveling liquid composition as either a single homogeneous mixture of the first and second resin components, or, where the depth of the housing is greater than the depth of UV penetration, as a cured mass wherein the first resin component is in a separate and discrete resin layer overlying a lower resin layer containing the second resin component but not the first resin component.

Upon heating, the adhesive crosslinks and the uncured rubber compound is preferably cured simultaneously. The adhesive is particularly useful in the fabrication of compositions by the bonding of cured polyurethane to an uncured rubber compound which becomes cured during the bonding process, such as in the construction of tires containing cured polyurethane reinforcements within uncured rubber carcasses, the retreading of tires containing polyurethane repairs, etc.

Abstract: Creped tissues having improved perceived softness and appearance are made from tissue webs having at least a machine direction broken line pattern of individual densified areas containing higher mass concentrations of fibers. The broken line pattern of densified areas creates a pleasing appearance and influences the creping to provide a more uniform crepe and hence improved tissue softness.
