Worbla's® KobraCast Art (WKA) – the most versatile Worbla's® ever!
Worbla's® KobraCast Art: You can simply call it the Jack of all trades from Cast4Art and just like all the products of the Worbla’s® Art Series it is produced solvent-free produced and to proceed and contains no hazardous substances.
It is activated by heat (best approx. 80-90°C/175-195°F) and can be shaped easily by hand or even thermoformed. WKA can be re-activated as often as you like and all leftovers can be re-used so there is almost no waste. It contains strong heat activated glue which means it sticks very well to itself and to other materials if treated properly.
What makes WKA so unique is the very stretchable, but tear-resistant mesh inside. This makes it possible to cast organic shapes (e.g. antlers). WKA stays a little flexible even after cooling down hence it is no problem separating it even from negative moulds including undercuts.
Worbla's® KobraCast Art's surface provides good adherence for glass colors & spray paint. It can also sew through it quite easily for attaching (faux)-leather & -furs, fabrics and more. Because the WKA is light-weight, it is ideal as a stabilising substructure to use for bags, corsets and much more!
