Claim 1

THE METHOD WHICH COMPRISES (A) MIXING (1) AN ORGANOSILICON POLYMER HAVING AN AVERAGE OF FROM ONE TO THREE GROUPS PER SILICA ATOM SELECTED FROM THE GROUP CONSISTING OF MONOVALENT HYMONOVALENT HALOHYDROCARBON RADICALS, AND CYANOALKYL RADICALS, THERE BEING AN AVERAGE PER ANOLKYL RADICALS, THERE BEING AN AVERAGE PER MOLECULE OF (1) AT LEAST TWO MONOVALENT HYDROCARBON RADICALS CONTAINING ALIPHATIC UNSATURATION, THE REMAINING VALENCES OF THE SILICON ATOMS OF THE SAID ORGANOSILICON POLYMER BEING SATISFIED BY SELECTION FROM THE GROUP CONSISTING OF DIVALENT OXYGEN ATOMS, DIVALENT HYDROCARBON RADICALS DIVALENT HYDROCARBON ETHER RADICALS AND DIVALENT HALOARYLENE RADICALS, SAID DIVALNET RADICALS LINKING SILICON ATOMS, (2) AN ORGANOSILICON COMPOUND CONTAINING SILICONBONDED HYDROGEN ATOMS, THERE BEING IN ADDITION AN AVERAGE OF UP TO TWO GROUPS PER SILICON ATOM SELECTED FROM THE GROUP CONSISTING OF MONOVALENT HYDROCARBON RADICALS FREE OF ALIPHATIC UNSATURATION, MONOVALENT HALOHYDROCARBON RADICALS FREE OF ALIPHATIC UNSATURATED AND CYANOALKYL RADICALS, THE REMAINING VALENCES OF THE SILICON ATOMS BEING SATISFIED BY GROUPS SELECTED FROM THE GROUP CONSISTING OF DIVALENT OXYGEN ATOMS, DIVALENT HYDROCARBON RADICAL FREE OF ALIPHATIC UNSATURATION, DIVALENTS HYDROCARBONS ETHER RADICALS FREE OF ALIPHATIC UNSATURATED AND DIVALENT HALOARYLENE RADICALS, SAID DIVALENT RADICALS LINKING SILICON ATOMS, THERE BEING AN AVERAGE AT LEAST TWO SILICON-BONDED HYDROGEN ATOMS PER MOLECULE OF (2), THE SUM OF THE AVERAGE NUMBER OF ALIPHATIC UNSATURATED MONOVALENT RADICALS PER MOLECEULE OF (1) AND THE AVERAGE NUMBER OF SILICON-BONDED HYDROGEN ATOMS PER MOLECULE OF (2) BEING GREATER THAN 4, (3) A PLATINUM CATALYSTA IN AN AMOUNT OF AT LEAST 0.1 PART PER MILLION PT BASED ON THE COMBINED WEIGHTS OF (1) AND (2), AND (4) SUFFICIENT BENZOTRIAZOLE TO REDUCE THE ACTIVITY TOWARD CURING, (B) AND HEATING THE MIXTURE TO CURE THE PRODUCT TO A COHERENT SOLID.
