Coating support strip in order to give it anti-adherent properties is carried out with the aid of a silicone composition containing at least one polyorganosiloxane (A) and at least one crosslinking agent (B), and which is crosslinked by hydrosilylation and/or dehydrogenation polycondensation, in presence of catalyst (C). Method comprises: 1) continuous mixing of compound(s) (A), which have reactive groups, compound(s) (B), which have reactive groups, and (C) to produce at least one pre-mixture (AB) and/or (AC) and/or (BC) whichever is easiest; 2) forwarding mixture to coating site; 3) coating strip; and 4) crosslinking product. Time spent in water bath is preferably 2 hours. Bath provides heating profile (Gaussian) with temperature T1 at start of peak, T2 at top of peak, and T3 at end of peak , such that T3 preferably = 80[deg]C, and T3-T1 = 15[deg]C and mid peak width is +- 4[deg]C. The rate of production of the mixture is such that the time spent in separating it and apply ing the coating is at most the time spent in bath. Also claimed are device for carrying out said method; and silicone composition produced by it. |
