Teroson PU 9100 GREY - 310 ml (adhesive and sealing mass, grey) / Terostat 9100

Product description:
TEROSON PU 9100 is a one component adhesive/sealant based on polyurethane, which cures by reaction with moisture to a soft elastic product. The skin formation and curing times are dependent on humidity and temperature. The cure through time also depends on joint depth. By increasing the temperature and moisture these times can be reduced. Low temperature as well as low moisture retards the process. Further information on the product can be obtained from the local technical department:

TEROSON PU 9100 exhibits the following properties:
- good adhesion to painted surfaces, many metals and plastics without primer
- can be overpainted
- sag resistant
- high curing speed
- excellent elasticity

Steps to achieve the best adhesive results:
The surfaces to be bonded or sealed must be dry, free of oil, dust, grease and other contaminants. For pretreatment we recommend the approved surface preparator of the TEROSON program (TEROSON VR 20), because other products for pretreatment may lead to incompatibilities.

TEROSON PU 9100 can be directly applied from cartridges employing standard air or hand operated guns. Low material temperature will lead to an increase of viscosity, resulting in a lower extrusion rate. This can be avoided by bringing the material up to room temperature prior to application. To avoid condensation it is necessary to bring the substrates up to room temperature. After application TEROSON PU 9100 can be smoothed with a spatula dipped in TEROSON VR 20.

After skin formation TEROSON PU 9100 can be painted over. The paint compatibility of the various paints has to be tested before use. Corrosion protection primer paints may only be applied on to cured TEROSON PU 9100, as these usually permit only very low water vapour transmission. In cases where accelerated paints drying in a drying oven or with IR radiation is required (max. 70°C), a pre-reaction/waiting period of minimum 30 minutes must be respected.
