Cool Blue Heat Paste - Welding Paste



These pics come from a new aerospace test facility that they are constructing at the University of Notre Dame. The SSF-6 is working great.

I am attempting to make all of these fittings air tight as they are used for pressure measurements. We can¹t have any leaks. I had very little warpage of my base metal and I think this is really going to work out very well.

Cool Blue Heat Absorbent Paste

Cool Blue heat paste is an all natural, cellulose-based product that prevents warping and damage by protecting heat-sensitive areas around the welding site. With this heat-resistant paste, you can make weld repairs without having to disassemble parts.  


Cool Blue paste can be used in any position and applied on a variety of surfaces, including wood, glass, chrome, plastic, vinyl, rubber, metal, and painted-on areas. It can even be used as a jig in jewelry applications and used in auto body jobs to prevent warping. The paste is reusable for life, protects up to 3000 degrees, wipes off easily, and will not dry on to the surface you've applied it to.


Although the paste is non-toxic and will not hurt your skin, it's best to wear gloves when handling the product. Before applying it on any surface, mix it up with an old spoon, scoop out enough paste, and spread a liberal amount of product on the surface you wish to protect.


After use, make sure to keep the Cool Blue heat paste moist by and replacing the lid. If it becomes dry, you may add water to rehydrate the product.
