Abstract: An improved method for embedding one or more sensors in SiC is provided. The method includes depositing a binder onto successive layers of a SiC powder feedstock to produce a dimensionally stable green body have a true-sized cavity. A sensor component is then press-fit into the true-sized cavity. Alternatively, the green body is printed around the sensor component. The assembly (the green body and the sensor component) is heated within a chemical vapor infiltration (CVI) chamber for debinding, and a precursor gas is introduced for densifying the SiC matrix material. During infiltration, the sensor component becomes bonded to the densified SiC matrix, the sensor component being selected to be thermodynamically compatible with CVI byproducts at elevated temperatures, including temperatures in excess of 1000° C.

Abstract: Isocyanate functional polymers useful as crosslinking agents or as moisture curing polymers, which comprise the addition polymerization reaction product of:(a) 1 to 100% by weight of at least one isocyanate functional ethylenically unsaturated monomer which comprises the reaction product obtained by the gradual addition of an ethylenically unsaturated monomer having a single active hydrogen to a diisocyanate selected from the group consisting of isophorone diisocyanate and 2,4 toluene diisocyanate wherein the final molar ratio of active hydrogen containing monomer to diisocyanate is essentially 1 to 1; and(b) 0 to 99% by weight of at least one ethylenically unsaturated monomer which is free of active hydrogen functionality and which is copolymerizable with the ethylenically unsaturated isocyanate functional monomer.
