Elastic adhesive allows instant handling

18 May 2013

Henkel Terostat silane modified polymers can be used in applications that require an elastic bond between medium to large bond surfaces.

They create friction-locked joints that are able to withstand dynamic loads, and as the stress is distributed evenly, material fatigue and failure is prevented. These adhesives are therefore useful for bonding structures subject to vibration.

Achieving a bond generally requires the elements to be held together in a clamping system or fixture until the adhesive has cured sufficiently for the structure to hold its own weight.  Whilst this is perfectly acceptable for many applications, others require a quicker fix and this is where the new Henkel Terostat MS 500 hot melt sealant really comes into its own.  

In a matter of seconds this 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.

It also saves on the overall weight of the structure, creates an effective seal and generally requires no substrate priming to optimise adhesion.
