Henkel MS939 MS Polymer Adhesive Sealant

TEROSON MS 939 is a gun-grade, one-component adhesive/sealant based on silane modified polymers, which cures by reaction with moisture to an elastic product.

Our expert says...

Henkel MS939 demonstrates good adhesion to many substrates and is compatible with suitable paint systems.


  • Demonstrates the strength necessary for elastic bonding.
  • Demonstrates good UV resistance and can therefore be used for interior and exterior applications.

Refer to Technical Data Sheet for full details.  Application from 290 mL cartridges is made with the TEROSON Hand or Air Pressure Pistols, and from plastic wallets (310 and 570 mL) with the corresponding FK-Hand or FK-Air Pressure Pistols. In the case of compressed air application a pressure of 2 to 5 bar is required.  Low material temperatures of the sealant will lead to an increase of viscosity, resulting in a lower extrusion rate. This can be avoided by bringing the sealant up to room temperature prior to application.  TEROSON MS 939 can also be applied from hobbocks or drums with high pressure pumps with follower plates.  See separate application directions of Teroson MS products in hobbocks and drums.
