Areas of Application

SikaBiresin® TD160 TD165 is used in art and decoration applications to make transparent coatings or sealing surfaces in thin layers from 1 to 3 mm (wood, paper, ceramic, etc).
It is well suited for art and decoration applications to make small objects up to 10 mm thick in silicone molds such jewellery, giftware, key chains or souvenirs.
This product is suitable for experienced professional users only. Tests under actual processing conditions and with additional materials such as coatings and release agents must be performed to proof material compatibility.

Application

Surface preparation

A liquid or pasty wax 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® TD160 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.
In thin layers coating (1 to 3 mm) a warm room (23 – 25 °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 7 hours.

 

For small cast parts produced using silicone molds, it is recommended not to exceed a thickness of 10 mm in order to prevent excessive exothermic reaction, which may adversely affect the cured surface quality. Alternatively and when possible lower resin and room temperatures to 18 – 20 °C or switch to slower system.
When casting 3 mm and above it will flow and self-level. For thinner and large surface it is possible to spread it out with a flexible spatula or a brush. 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® TD160 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.
