Product description:
TEROSON MS 9220 is a one component adhesive with high sag resistance, based on MS-Polymer. The material cures by reaction with humidity to an elastic product. The skin formation and curing times are dependent on humidity and temperature, and the curing time also depends on joint depth. By increasing the temperature and humidity, the reaction time can be reduced; low temperatures as well as low humidity retard the process. TEROSON MS 9220 is free of solvents, isocyanates, silicones and PVC, and has only a weak odour (after curing it is odourless). It demonstrates good adhesion to many substrates.The material demonstrates good resistanceto UV-light and can therefore be used for exterior applications.

Application Areas:
TEROSON MS 9220 is used in the areas:
- vehicle body manufature
- bus manufacture
- vehicle body build-ups
- caravan
- ship and boat building

Steps to achieve the best adhesive results:
Pre-Treatment
The substrates must be clean, dry and grease free. For pretreatment TEROSON VR 20 and TEROSON D are suitable.

General remarks
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. If substrates are too cold temperature may fall below dew point causing condesnation. This can be avoided by bringing the substrates up to room temperature in time.

Application
TEROSON MS 9220 can directly be applied from cartridges employing standard air or hand operated guns. In case of compressed air application a pressure of 2-5 bar is required, depending on nozzle aperture and application speed. When applying TEROSON MS 9220 in closed rooms, it is important to ventilate well during the curing process.

Cleaning
For cleaning application equipment contaminated with uncured TEROSON MS 9220 we recommend the use of cleaner TEROSON D. Cured material can only be removed mechanically.
