Patent ID: 7547369

Claim:
A method for applying a ceramic coating to a substrate comprising: a. applying a tackifying resin to at least one of a green ceramic tape and a rigid substrate, i. wherein the green ceramic tape comprises a solids portion and an organics portion, ii. wherein the solids portion comprises a glass component, iii. wherein the organics portion comprises a polymer resin, iv. wherein the tackifying resin is selected from the group consisting of rosin resins, terpene resins, hydrocarbon resins and combinations thereof, and v. wherein the thermal degradation initiation temperature of the tackifying resin is lower than the thermal degradation initiation temperature of the polymer resin, vi. wherein the thermal degradation completion temperature of the tackifying resin is no greater than that of the resin used in the green ceramic tape, b. laminating together at a lamination pressure of less than about 100 psi, the green ceramic tape and the substrate to form a monolith, and c. firing the monolith at a temperature and a time sufficient to flow and densify the glass component, d. wherein the green ceramic tape exhibits less than 5% area shrinkage during firing.
