In electrical equipment that generates heat, cable bundles must be durably protected against high temperatures. With Terostat 3631 FR, Henkel has developed a flame retardant and easily applied butyl sealant which is especially suitable for applications where low flammability is essential.

Unlike conventional butyl-based sealants, Terostat 3631 FR easily withstands continuous exposure to temperatures up to 105°C and also has self-extinguishing properties in the event of a fire. As a result, Terostat 3631 FR is suited for use as a longitudinal water-repellent sealant for cable bundles in electric ovens, microwaves, heating systems or tumble dryers.

In addition to high-grade thermal protection, a further advantage offered by the sealant is its easy handling and excellent resistance to water and moisture. As a soft-moldable compound, Terostat 3631 FR is simply applied manually to seal off the cable bundle. This eliminates the fiddly work required in many cases to thread cables through grommets. Moreover, when applied hot, the sealant can also be processed automatically.
