Henkel has introduced Terostat MS 500 hot-melt sealant to provide the quick fix demanded by some applications. The company’s silane modified polymers are suitable for use where an elastic bond is required between medium and large bond surfaces and are used to bond any structures that need to withstand vibration such as washing machines, buses and trains. Terostat MS 500 has been designed specifically for bonding and sealing crystalline solar modules.

In seconds, the Terostat MS 500 thixotropic adhesive ‘grabs’ the marrying substrate, creating high initial bond strength that allows immediate handling. As it dries, it cross-links through moisture absorption, curing in as little as 20 or 30 minutes.

Terostat MS 500 effectively compensates for the differing thermal expansion characteristics of dissimilar materials and remains flexible over a wide temperature range.

From a manufacturing standpoint, the product has the ability to reduce production time and costs while improving performance and aesthetics. It also saves on the overall weight of the structure, creates an effective seal and generally requires no substrate priming to optimise adhesion.

Application example

  • Terostat MS 500 was developed to meet the needs of a specific application: the bonding and sealing of crystalline solar modules.
  • However, one of the first UK applications for which Terostat MS 500 proved suitable was bonding and sealing caravan panels.
  • The manufacturer was already using flexible structural bonding technology but needed to screw panels to struts as a support mechanism during the curing process.
  • Thanks to Terostat MS 500 and its ability to provide an instant bond, the screws are no longer needed.
  • This has eliminated a process, saving costs, and greatly improved the quality of the end product as there are no screw holes to create leak paths.
