HEAT STOP is a gel which  protects surfaces and components from heat damage during soldering, brazing and welding. It acts like a "protective shield" and prevents e.g. a release of seals, parts stretch significantly less, sensitive components are protected.
HEAT STOP protects painted and finished surfaces from discoloration due to the use of torch systems. The specially gelled formula sticks to any surface without dripping or running off.
HEAT STOP reduces the deformation of surfaces and materials such as plastic, rubber, sealants and gaskets.
