Abstract: A curable organosilicon composition comprises a component having silicon-bonded hydrogen atoms, a component having silicon-bonded radicals reactive therewith, a curing catalyst, a catalyst-inhibitor and a bath life extender. The use of certain compounds, which are ineffective as a bath life extender in the absence of a catalyst inhibitor, effectively extend the room temperature bath life of a silicone coating composition containing a catalyst inhibitor. Being a substantial non-inhibitor for the catalyst the bath life extender component does not effect the cure time and/or cure temperature of the composition.This discovery has permitted the preparation of curable coating compositions which have a long bath life at room temperature and a rapid cure time at elevated temperatures which does not drift to longer intervals as the coating compositions ages over a typical production run.

Abstract: The start-up of a free-falling liquid curtain (12) in the coating of objects or a moving web (18) using curtain coaters is considerably improved by the controlled retraction of a catch pan device (30) positioned in close proximity to the moving web (18). The catch pan device which includes a primary lip (32), and a secondary lip (44), is positioned so that it can be retracted through the falling curtain at a predetermined speed and direction relative to the moving web (18). The device (30) is retracted at the start of a coating process so that the falling curtain is interrupted first by primary lip (32) and then secondary lip (44). Primary lip (32) prevents the coating liquids from flowing onto the moving web (18) during the start-up process and secondary lip (44) retains the coating liquids of an extended falling curtain resulting from contact between the curtain and primary lip (32).
