Polysilazane coating method and device

A polysilazane coating method for limiting fragmentation of polysilazane, the method comprising the steps of

• i) preparing a coating composition, wherein the preparation of the coating composition comprises the sub-steps of
• a. introducing a component A into a coating composition vessel;
• b. introducing a component B into the coating composition vessel and mixing component B with component A, and
• c. introducing a component C into the coating composition vessel and mixing component C with components A and B;
• wherein the components A, B, and C each are chosen from a group of polysilazanes, a group of catalysts, or a group of reactive nanomaterials and/or reactive molecules that can react spontaneously with a polysilazane polymer backbone to cause fragmentation;
• wherein the components A, B, and C are all chosen from different groups;
• wherein the choice of group for each of the components A, B and C are predetermined based on the known reactivity of the components towards each other;
• ii) applying the coating composition to a substrate;
• wherein step ii) is initiated at a predetermined time period tii based on the known reactivity of the components towards each other;
• wherein the predetermined time period tii is chosen so that 1≤tii≤1200 seconds;
• wherein the introduction of component C in sub-step ic) is initiated a predetermined time period to tc after the introduction of component B in sub-step ib);
• and wherein tc is chosen so that 0<tc<900 seconds.
