Marker system
A marker system for applying to surfaces of items, articles, goods, vehicles and/or premises, said marker system comprising: a marker comprising a temperature resilient medium having a predefined carbonization temperature capable of securing the marker system onto a surface; wherein the medium contains an inorganic matrix having a predefined fusing point lower than the predefined carbonization temperature of the medium; such that when the marker system is subjected to temperatures above the predefined carbonization temperature of the medium, the inorganic matrix fuses to the marker to form an adhesive protective layer thereby securing the marker onto said surface. A composition comprising the marker system. An item, an article, a good, a vehicle and/or premises comprising a surface impregnated with the marker system.
1. A marker system for applying to surfaces of items, articles, goods, vehicles and/or premises, said marker system comprising:
a marker comprising a temperature resilient medium, the marker having i) an aqueous polymer emulsion capable of securing the marker system onto a surface, ii) a predefined carbonisation temperature, wherein the temperature resilient medium includes an inorganic matrix having a predefined fusing point lower than the predefined carbonisation temperature of the temperature resilient medium, and iii) a fingerprint configured to distinguish one marker system from another and to identify a source of an item to which the marker is applied;
the inorganic matrix configured to, in response to being subjected to temperatures above the predefined carbonisation temperature of the medium, fuse to the marker to form an adhesive protective layer thereby encapsulating the marker onto said surface.
2. The marker system of claim 1 , wherein the adhesive layer substantially preserves the integrity of the marker.
3. The marker system of claim 1 , wherein the inorganic matrix is a ground glass.
4. The marker system of claim 3 , wherein the glass is a finely ground glass.
5. The marker system of claim 3 , wherein the ground glass constitutes approximately 20% wt/wt of the marker.
6. The marker system of claim 1 , wherein the medium is an organic medium.
7. The marker system of any claim 6 , wherein the medium comprises an aqueous acrylate emulsion.
8. The marker system of claim 1 , wherein the medium comprises a material having a high inherent stability that is resistant to environmental conditions and/or removal through washing or abrasion.
9. A marker system of claim 1 , wherein the marker further comprises a fingerprint.
10. The marker system of claim 9 , wherein the fingerprint is an organometalic fingerprint.
11. The marker system of claim 9 , wherein the fingerprint comprises a unique identifying tracer.
12. The marker system of claim 1 , wherein the marker further comprises an indicator.
13. The marker system of claim 12 , wherein the indicator comprises an inorganic indicator.
14. The marker system of claim 12 , wherein the indicator comprises at least one material capable of phosphorescing when subjected to stimulus.
15. The marker system of claim 12 , wherein the indicator comprises at least one material capable of emitting visible or near infra red radiation at a specific frequency when subjected to infra-red stimulus.
16. The marker system of claim 12 , wherein the indicator comprises at least one material capable of emitting visible or near infra red radiation when subjected to ultra-violet stimulus.
17. The marker system of claim 1 , wherein the surfaces of items, articles, goods, vehicles and/or premises comprise metal surfaces.
18. The marker system of claim 1 , wherein the matrix is capable of preserving the integrity of the markers at high temperatures.
19. The marker system of claim 18 , wherein the high temperatures include temperatures in excess of 1000° C.
