Sika TD150 is a casting epoxy resin formulated with highly translucent components with very good UV stability. It was developed for the production of foundry and decorative objects requiring a meticulous finish, prototypes of bottles, jewelry, river table, furniture, etc.
working thickness 0.1 to 10cm
This coating resin is preferably used as a casting resin without reinforcements because of its very light color and its hardening without cracks. Unlike polyester casting resins, epoxy resin hardens without shrinking (<2%), providing a shiny surface that does not stick. Organic and inorganic preparations and metals are suitable for coating. Objects must be dry and non-porous (risk of bubbles if air is trapped in the objects).
The very low reactivity allows casting a high layer thickness without color change.
The resin has high clarity and does not create yellowing.
Dries at room temperature.
Very easy mixing and excellent degassing.
Very good UV resistance
Almost odorless.
Excellent resistance to physical shock and thermal shock .
Mix Ratio :
100: 45 by weight. (100gr of resin for 45gr of hardener)
100: 50 by volume. (100ml of resin for 50ml of hardener)
Implementation:
- The ambient temperature is the essential parameter for a successful casting of SikaBiresin® TD150 / TD165. There is a causal relationship between the ambient temperature (AT), the volume of resin poured and the cure time. A fast hardening due to high ambient temperatures create high exothermic reaction and the hardened resin may become yellow with marks on top.
- In surface casting on endCoats (1 to 5 mm), an ambient temperature (25 - 30 ° C) is recommended to accelerate the hardening and obtain the best properties.
- Mixing must be done manually or with a mixer. Be careful not to incorporate too much air when mixing. An emulsion should be avoided.
- After a first mixing in a bucket, pour the product into a second bucket to complete the mixing. Thoroughly scrape the sides of the mixing bucket. Allow the mixture to auto-debull for at least 10 minutes before pouring, otherwise, make
vacuum casting.
- Due to the long pot life and the low viscosity of the product, the casting frame must be completely waterproof. Cured resin will not adhere to brown packing tape and it can be used for corners and other places where resin should not stick to the backing.
- Liquid or paste wax can also be used to prevent sticking on models or supports. Wood or porous surfaces of models must be1px; font-size: 15px; font-family: sans-serif; transform: scaleX (0.954158); "role =" presentation "dir =" ltr "> treated with a suitable pore sealer. Quick-setting epoxy or varnish can be used before casting to protect porous surfaces Let them harden well before pouring the resin.
- After pouring and a suitable waiting time, the remaining bubbles can easily be removed with a heat gun (sweep the surface from a distance of 15-20 cm).
- Light sanding and varnishing is almost always necessary to achieve the desired glossy and flat effect. Use the proper tools to avoid heating the resin when sanding. Wet sanding is recommended.
- Polishing paste on a pad gives the best finish. Do not overheat the casting layer to avoid marks.
Calculate the quantity needed:
Width x Height x Length divided by 1000.
Ex: 10cm x 5cm x 100cm = 5000/1000 = 5 Liters
The mistakes not to make.
