Abstract
A medium temperature conductive-resistive article employing graphite suspended in a high temperature polymer based activator and water is disclosed. The conductive-resistive substance can be applied to a fabric-like substrate in order to provide an electrical resistive temperature adjustable heating element which can alter the temperature of the fabric-like substrate when electrical current is permitted to flow through the conductive-resistive substance. A process of making the article is also disclosed.
Claims21
An electrical resistant temperature adjustable article, which comprises:
- a first substrate;
- and
- a medium temperature conductive-resistive coating applied to said substrate, said medium temperature conductive-resistive coating comprising 10-30 weight percent graphite having a particle size from about 150 to about 325 mesh, 20-65 weight percent polymer latex and 6 to 60 weight percent total water based on 100 weight percent total composition;
- wherein said article is capable of having its temperature adjusted between ambient temperature and 400.degree. F.
A method of providing temperature-adjustment capability to a substrate comprising applying a coating of a medium temperature conductive-resistive substance to said substrate, said medium-temperature conductive-resistive substance comprising 10-30 weight percent graphite having a particle size from about 150 to about 325 mesh, 20-65 weight percent polymer latex and 6 to 60 weight percent total water based on 100 weight percent total composition, wherein said article is capable of temperature adjustment between ambient temperature and 400.degree. F.
