good luck, being that this one website you listed is the only one on the entire
internet that seems to know what Dacon/Dakon is, its going to be your one and only source.
Another option would be to sample other readily available self
adhesive materials and see see if those materials can do what the dacon/dakon does for you.
good luck....
Polycaprolactone (
PCL) also has many applications in the hobbyist market where it is known as Re-Form, Polydoh, Plastimake, NiftyFix, Protoplastic, InstaMorph, Polymorph, Shapelock, ReMoldables, Plastdude or TechTack. It has
physical properties of a very tough, nylon-like plastic that softens to a putty-like consistency at only 60 °C, easily achieved by immersing in hot
water.
[8] PCL's specific heat and conductivity are low enough that it is not hard to handle by hand at this temperature. This makes it ideal for small-scale modeling, part fabrication,
repair of plastic objects, and
rapid prototyping where heat resistance is not needed. Though softened PCL readily sticks to many other plastics when at higher temperature, if the surface is cooled, the stickiness can be minimized while still leaving the mass pliable.
