Reinforced non-stick coating system

A coating system, comprising:

• a basecoat composition, comprising at least one of:
• (i) at least one siloxane of formula (I)
• RxSi(OR′)4-x (I)
• wherein:
• R is one or more moieties chosen independently from linear, branched, or cyclic alkyl and aryl;
• R′ is methyl, ethyl, propyl or alkyl;
• and
• x is 0, 1, 2, or 3;
• and
• (ii) an organic polymer having at least one of
• a melt point of 200° C. or greater as determined by differential scanning calorimetry (DSC);
• a glass transition temperature of 90° C. or greater as determined by differential scanning calorimetry (DSC);
• and
• a heat deflection/distortion temperature of 100° C. or greater as determined by ASTM D648;
• and
• (iii) a silicone resin;
• and
• reinforcing particles having a Knoop hardness of 160 kg/m2 as determined by ASTM C1326;
• and an average particle size (D50) of 5 microns to 100 microns, as determined by dynamic light scattering;
• and
• an overcoat composition, comprising at least one organosiloxane, and
• at least one catalyst.

A coated article, comprising:

• a substrate having a surface;
• and
• a coating disposed on the surface, comprising:
• a basecoat having at least one of:
• a Martens hardness of 0.2 GPa or higher, as determined by nano-indentation according to DIN ISO 14577 1-3;
• and
• an elastic modulus of 5 GPa or higher, as determined by DIN ISO 14577 1-3;
• and
• the basecoat comprising at least one of a sol-gel matrix, an organic polymer, and a silicone resin, the basecoat including reinforcing particles having a Knoop hardness of at least 160 kg/m2 as determined by ASTM C1326;
• and
• an overcoat disposed on the basecoat and comprising a siloxane matrix, the overcoat having a Martens hardness less than the Martens hardness of the basecoat, and further comprising:
• a vinyl-terminated polydimethylsiloxane;
• a polydimethylsiloxane including hydride groups;
• a co-binder comprising a vinyl Q resin;
• and
• filler particles having an aspect ratio of length to width of at least 3:1.
