Abstract

The invention described herein generally pertains to temperature-indicating foam gun nozzles and/or at least one temperature-indicating hose which employs at least one thermochromic material disposed within said foam gun nozzle and/or hoses.

Claims

1. A two-component spray gun comprising:

a housing having a pair of inlet openings positioned in a canted orientation on top of said housing for insertion of an “

A” and

a “

B”

flexible plastic hose from respective “

A” and

“

B”

cylinders containing chemicals therein;

said housing having a metering valve disposed within said housing;

said housing having a removable plastic spray nozzle affixed to a front of said housing, said plastic spray nozzle comprising at least one thermochromic material disposed within or affixed thereupon said plastic nozzle.

2. The spray gun of claim 1 wherein

said at least one thermochromic material is a liquid crystal or a leuco dye.

3. The spray gun of claim 1 wherein

said thermochromic material is affixed upon said plastic nozzle by a label containing said thermochromic material.

4. The spray gun of claim 1 wherein

said at least one thermochromic material is at least two thermochromic materials disposed within or thereupon said nozzle, each of said at least two thermochromic materials effecting a color change at a different temperature.

5. The spray gun of claim 4 wherein

said at least one thermochromic material is at least three thermochromic materials disposed within or thereupon said nozzle, each of said at least three thermochromic materials effecting a color change at a different temperature.

6. The spray gun of claim 1 wherein

at least one of said “

A” and

“

B”

plastic hoses affixed to said housing of said spray gun comprise at least one thermochromic material disposed within or affixed thereupon said at least one plastic hoses.

7. The spray gun of claim 6 wherein

said at least one thermochromic material is a liquid crystal or a leuco dye.

8. The spray gun of claim 6 wherein

said thermochromic material is affixed upon at least one of said plastic hoses by a label containing said at least one thermochromic material.

9. The spray gun of claim 6 wherein

said at least one thermochromic material is at least two thermochromic materials disposed within or thereupon said at least one plastic hose, each of said at least two thermochromic materials effecting a color change at a different temperature.

10. The spray gun of claim 4 wherein

said at least one thermochromic material is at least three thermochromic materials disposed within or thereupon said at least one plastic hose, each of said at least three thermochromic materials effecting a color change at a different temperature.

11. A process to determine if chemicals used to make a two-component foam are at or above an acceptable use temperature range, the process comprising:

using a spray gun having a nozzle comprising at least one thermochromic material contained therein or affixed thereupon.

12. The process of claim 11 which further comprises:

using at least one “

A”

or “

B”

side hose comprising at least one thermochromic material contained therein or affixed thereupon.
