Henkel Launches Heat-conductive Butyl Sealant for Refrigeration Appliances

Published on 2011-05-11. Author : SpecialChem

Sealants with new properties offer advantageous design possibilities in numerous industrial manufacturing processes. One such sealant that is especially suitable for use in refrigeration equipment is Terostat 301. In these applications the first heat-conductive butyl sealant from Henkel replaces classic heat-conductive pastes to improve heat exchange between the inner housing and the heat exchanger.

The product has a heat conductivity rating of approx. 0.8 W/mK. At the same time it also provides durable fixing of the coils to the refrigerator housing - unlike heat-conductive pasts which require an extra step to fix the coils using adhesive tapes or screw-fasteners. Terostat 301 is highly tacky and adheres to nearly all materials. For processing, the product is heated to 120 to 140°C and can then be applied automatically at high speed. The sealant develops its full performance characteristics directly after application. In other words, no curing time is required. In addition to its use in refrigerators, Terostat 301 can also be employed in sanitary applications or heating systems, where it can improve the heat transfer to thermostats or sensors.
