Abstract
Disclosed are coating compositions which include a preceramic silicon-containing material dissolved in short chain linear siloxanes. The compositions have a long shelf life and are useful for forming coatings which are thick and of good quality.
Claims25
A coating composition comprising:
- about 1 and about 50 weight percent preceramic silicon-containing material and about 50 to about 99 weight percent of a mixture of hexamethyldisiloxane and octamethyltrisiloxane in a ratio of 10:90 to 90:10.
A coating composition comprising:
- about 1 and about 50 weight percent hydrogen silsesquioxane resin and about 50 to about 99 weight percent of a mixture of hexamethyldisiloxane and octamethyltrisiloxane in a ratio of 10:90 to 90:10.
A method of coating an electronic substrate comprising:
- applying a coating composition comprising about 1 and about 50 weight percent preceramic silicon-containing material and about 50 to about 99 weight percent of a mixture of hexamethyldisiloxane and octamethyltrisiloxane in a ratio of 10:90 to 90:10 onto an electronic substrate.
A method of coating an electronic substrate comprising:
- applying a coating composition comprising about 1 and about 50 weight percent hydrogen silsesquioxane resin and about 50 to about 99 weight percent of a mixture of hexamethyldisiloxane and octamethyltrisiloxane in a ratio of 10:90 to 90:10 onto an electronic substrate.
A coating composition comprising about 1 to about 50 weight percent preceramic silicon-containing material and about 50 to about 99 weight percent octamethyltrisiloxane.
A coating composition comprising about 1 and about 50 weight percent preceramic silicon-containing material and about 50 to about 99 weight percent decamethyltetrasiloxane.
A method of coating an electronic substrate comprising:
- applying a coating composition comprising about 1 to about 50 weight percent preceramic silicon-containing material and about 50 to about 99 weight percent of a linear siloxane selected from the group consisting of octamethyltrisiloxane and decamethyltetrasiloxane onto an electronic substrate;
- and
- heating the coated electronic substrate to a temperature in the range of about 50.degree. C. to about 800.degree. C. to convert the coating composition into a ceramic coating.
