Abstract
A cold process for laying a textured or polished coat of bronze, copper, brass, pewter or other metallic substance over a mineral or organic surface comprises the step of mixing a sintering metal powder with a polyester resin and a ketonic catalyst for forming a spreadable, moldable or sprayable paste that hardens to a coat having essentially the mechanical and chemical characteristics of the selected metallic substance, but exhibiting no electrical conductivity.
Claims16
A process for coating a surface with a metal-and-resin composition, said process comprising:
- forming at room temperature, a mixture of spreadable paste of up to 91% per weight of an atomized sintering metal powder having particle sizes from 2 to 150 microns with a thermosetting synthetic resin which cures to hardness when heated;
- admixing a catalyst;
- applying said mixture in an unliquified, malleable state over polished and non-polished areas of said surface;
- curing said mixture to hardness at ambient temperature up to 150.degree. C.;
- and
- finishing said applied and hardened mixture.
A process for coating a surface with a metal-and-resin composition said process comprising:
- forming at room temperature, a spreadable paste with a first volume of sintering metal power and a second volume of thermosetting isophthalic, acid-based polyester resin;
- admixing a catalyst;
- applying said paste in an unliquified, malleable state over said surface;
- and
- curing said paste to hardness at a temperature of up to 150.degree. C.
A process for coating a surface with an electrically non-conductive metallic substance which comprises:
- forming, at room temperature, a viscous mixture of up to 91% per volume of a sintering metal powder and an isophthalic acid-based polyester resin wherein said sintering metal powder is selected from a group consisting of oxidized copper granules, oxidized copper alloy granules, gold granules and oxidized silver granules;
- admixing a catalyst;
- applying said mixture to said surface;
- and
- curing said mixture at ambient temperature of up to 150.degree. C.
