Product Details

As shown in this video Heat-Shielding Gel is a heat-shielding product that is available as a spray-on gel or as a more effective paste. It can temporarily shield virtually any solid material from temperatures up to an incredible 7500 ºF (4100 ºC). Once applied to a material, it acts both as a heat shield and as a heat sink, absorbing heat from the material. This material can make red-hot metals cool enough to touch in seconds and can keep fires from reigniting. Heat-Shielding Gel is non-toxic and environmentally safe.

Heat quickly causes the water content in Heat-Shielding Gel to evaporate, leaving a white crystalline material, which reflects heat away. The paste consists of about 2½ times more of this crystalline material than the gel has, making it suitable for applications where users need the most heat protection possible. When wet, the gel and paste can be cleaned up with a cloth or even wiped away by hand. After heating, it takes 24 to 36 hours to completely dry out and then can be cleaned up with a damp cloth.

Heat-Shielding Gel is mostly used during welding or soldering. Adjacent materials can be treated to reduce their exposure to heat and prevent damages. The work piece itself can also be coated, using it as a heat sink and preventing the heat from traveling inside the material and causing damage to fittings and fixtures. Main areas of application include plumbing, HVAC, automotive, auto body and jewelry design.

What is unique about this item for product developers?

It is a non-toxic, environmentally safe heat-shielding and heat-absorbing gel. It can be applied to any surface and will completely protect the surface adjacent to the welding, soldering, or brazing area.

What are the primary disadvantages of the existing technologies that this is an alternative for?

The current technologies are 35 years old and only absorb heat. They are not as effective at absorbing the heat as Heat-Shielding Gel—and they do not shield the heat.

What industries is this item typically used in?

Heating, air conditioning and refrigeration, plumbing, welding, jewelry repair, industrial maintenance, automotive repair and auto body, film special effects, ship building and repair, and electric motor repair.

Any other points you feel strongly should be included:

We have applied the Heat-Shielding Gel to a plastic water bottle and taken a torch to the bottle for about 60 seconds and then wiped the gel off. There was no damage to the bottle or the film label, which is often damaged by the heat of a hair dryer. No other product offers this kind of shielding.

Is this product skin safe?


Is this product harmful for the environment?


What is the melting point of this material?

Greater than 7500 ºF

What other materials, aside from plastic and metal, can this product be used on?

Any solid material.
