Patent ID: 11708472

Abstract:
In a heat-shielding film formed of addition-curing silicone resin containing organopolysiloxane, organopolysiloxane includes the combination of a plurality of units including at least a R1SiO3/2 unit (a T unit), a R2R3SiO2/2 unit (a D unit), and a R4R5R6SiO1/2 unit (a M unit) (in each unit, R1 to R6 is aliphatic hydrocarbon or hydrogen), and the molar ratio of the T unit, the D unit, and the M unit among all structural units is T:33.3 mol % to 71.4 mol %, D:11.1 mol % to 42.9 mol %, and M:7.0 mol % to 42.9 mol %.
