Application

Surface preparation

For products with long pot life and low viscosity the casting frame must be perfectly tight.
In case of simple and flat surfaces, a tape could be used as casting frame. Apply the tape around the border with the desired offset and make sure it is tight. The resin usually does not adhere to the tape.
A liquid or pasty wax release agent could be used to prevent adhesion on models and supports.
Wood or other porous surfaces of models must be sealed before casting process. The product itself, quick setting epoxy or a varnish could be used. These sealers must be cured prior to the casting process.

Application

An adequate ambient temperature is the most important parameter to successfully cast SikaBiresin® TD150 TD165. There is a link between ambient temperature, volume and layer thickness. Excessive thickness or higher ambient temperature may induce high exothermic reaction leading to yellowing, cracks or uneven surface once cured. If increased casting thicknesses are required, it is recommended to ensure a low ambient temperature and to cast the material immediately after mixing and degassing.
In thin layers coating (1 to 5 mm) a warm room (25 – 30 °C) is advised to speed up curing and get best properties. Prior to the next casting step, allow the material to reach its tack-free time, typically after 8 – 9 hours.
After casting and some relaxation time the bubbles close to the surface can easily be removed with a hot airstream. Use a hot air gun and sweep the surface at 15 – 20 cm distance avoiding to treat single spots (always sweeping).
To get on flat surfaces best transparent and shiny results, a sanding and polishing process may be necessary. Water sandpaper is recommended. Use appropriate tools to avoid heat on the SikaBiresin® TD150 TD165 while polishing.
Polishing paste on a buffer is giving the best finishing. Do not heat up too much the casting layer when polishing in order to avoid marks.

STORAGE CONDITIONS

Both components must be stored at temperature between 15 °C and 25 °C in original unopened containers.
